Serious question:

How could I make money with a quadcopter? I've heard real estate photography is pretty good, but I don't have a car (though I do have a bike and legs) so it would be a bit difficult.

I just got a chinese CC3D kit in the mail. The power distribution board didn't really work out sandwiched between the frame so I went with wires.

I think I need to resolder everything because it doesn't seem to power things smoothly. I tried to fire it up and it nearly flipped itself because the motors were jumping from idle to high power.

I'll have some wire and heat shrink next week to redo it.

>>888323
Depends on the grade of camera you've got on your quad. On something like a Syma X5C? Forget it. On a Phantom? We may be getting somewhere.

If you're in the US, though, it's illegal to fly multirotors commercially without a Section 333 exemption (you have to have at least a sport pilot's license).

FED GET OUT REEEEE

gotta love cheap chinese quadcopters, 33041 and FQ777-124 are great

7km out and back with a Twinstar. I actually wanted to go up a mountain but I did not know the mountain line was at an angle. So the right side was much further back then the left side...

First run with the stabilizer. (needs some tuning)

>>890042
probably incase a crash and a leg broke off. then they would have some travel.

>>888314
Is it your first build? If so don't worry, I've crashed my ZMR250 plenty of times and it's still okay.

>>890042
>>890189

I was lazy and didn't trim the motor wires so it was easier to solder.

Not worried about crashing and breaking stuff, it's a necessary part of progression. Unfortunately it's been super windy in NZ for the last few weeks so haven't been out for a proper fly yet

I have a naze32-based quad right now.
After doing some research I get this feeling that if I want to add a few more motors and features (say, for normal land-based wheeled motion and staff like that) and I don't have extra PWM ports it's actually a better idea to get a second FC board with separate Rx and just switch to it when landed — as opposed to trying to shove more features onto the first FC board and it's six control channels, that is.
Thoughts? (Let's assume that I will be able to get all these things within the weight limit of parent setup.)

Realistically how much would I expect to pay making a quad or plane with a camera to.fly by wire with? Not literally fly by wire, just a HUD display like a remote a cockpit.

I want to make out for /out/ivities.

>>890297
The simpliest quad with real-time video feed costs about 100-150$.
It only works up to about 100 meters or something like that and has about 5-10 minutes of battery life.
All-in-all DIY projects start at about the same price tag — but can have better (or worse, lol) parameters.
So the question is — how far do you want to go and how long to you want to stay in the air?

Are drones a Reddit meme like vaping and atheism?

Because RC aircraft have been around for decades in hobby circles.

I don't understand what the fucking deal is, honestly.

>>890335
It's the ease of use. RC-Flight takes skill.
Multirotor platforms became possible with stabilisation systems. But they didn't just became stable, they became easy enogh to be flown by an unskilled person. In contrast to usual modell aircraft you can take your hands of the remote for several seconds and don't end up crashing.

>>890340

Thanks for the thoughtful reply.

>>890340
As a side note — better stability and lower prices also resulted in much smoother and more forgiving learning curve, where you can learn to fly an inexpensive, safe (50g of weight are just NOT going to have enough momentum to do any serious damage) and virtually indestructable micro-sized stuff.

>>890347
Yea, good call. IIRC Single axis gyros were available for quite a while but they used to be rather expensive.

>>890303
Hmm. I wanted to take it camping and skim above the trees, or scout out some cliffs for caves.

Distance would be minimal, but maybe 1/hr flight between charges? Assuming a solar charger would be capable of charging it.

>>890576
1 hours flight time (or 30 minutes even) and being able to actually see caves (or what-not) from above the trees (I assume you don't magically have great FPV piloting skill to be able to pilot it by FPV among the trees) actually means we are looking at something that will most likely costs you 1000$ or more.

>>890335
ive wondered what the big deal is about RC drones too. I'm a real pilot and I hear about it nonstop.

I think Its really because its a platform you can do stuff on, instead of purely an entertainment thing like an RC 172 is. And anyone can do it, nearly right off the bat.

I just saw at target today they have a parrot bebop you can just buy off the shelf and have fly-to gps locations, fpv to remote and other stuff. the really expensive ones you have to actually try to crash them. also you dont need a rc airfield where the regulars are utter and complete cockmunchers most of the time.

i think they are a little fad-y right now but i dunno, they get cheaper and better but no less practical so more people want them. whats really gonna make them blow up is when amazon gets their faa rules pushed through.breace yourselves when that goes down

>>890724
>I think Its really because its a platform you can do stuff on, instead of purely an entertainment thing like an RC 172 is. And anyone can do it, nearly right off the bat.

This is it.

RC flight is hard, especially if you start talking about something like 3D helis (your first few hours are just trying to hover, then not break it when you land).

Multicoptors are stupidly stable, even if you're talking about full acro mode (3D is more complicated, but few will be dumb enough to jump in there with no experience), you can be up and doing crazy shit both because of the inherent stability and the onboard electronics.

Multis are a massive shortcut in the learning curve.

Add into that that doing shit like video/photos which are cool just because it's a view you don't often see...

Just started hand drawing up plans for a gas powered airplane. Construction will be balsa wood skeleton with monokote skin, wingspan is 48" chord of 9.5" and Fuselage length will be 36".

Any tips for balancing center of lift and gravity? I haven't bought a motor or servos/radio. What brands do I look for?

Also I don't expect this to p.fly first time. Tweaking the model is what I'm excited for.

I got a 250 racing quad, and have been loving it. I am getting a good bit better at it but I cant fly in acro mode well enough to actually fly around with it unless I am high up.

Still it was a great buy and I am overall really happy for it.

How do I get into this kinda stuff?
I'm more interested in the plane style over the quad copter.

Hello guys! My name is Mike and I have a question for you all.

The question is below this sentence:

What is a good drone that has an included camera and a remote (with screen! or I can use smartphone as screen but preferably with screen) that has a DECENT range?

Most drones I find are 30meters which is not far at all. I have now some beginner experience with a small nano drone for inside, but I want to learn to fly a drone with camera for outside too. One with a camera on board so I can fly in first person. I have hard time orientating when I turn 180 degrees (when the controls are reversed) and i hoped flying in 1st person would make stuff easier. Since I am already very good at flying games on the computer, I think first person drone flying is gonna be good for me.

But 30 meters does not seem far at all. I rather have 100 or even 300 meters.

So is there anything like in the 100 dollar range that does this?
Thanks for your reading and replies! cya around

>>890335
its very easy to fly, i bought a small nano one for 30 bucks when i was drunk and mastered it within the same night

This seems to be the only way the esc fits, I'm afraid the capacitor might break off. Wat do?

Is there something in the tube preventing you from putting the cap into the tube? Aka rotate it 180°, route cables below esc into the tube.

Sup anon, I want to send flight commands from my application on iPhone to quadcopter. What should I use as flight controller? I've evaluated two ways:

Use Arduino + MPU-6050 + Arduino-Quadcopter. Send commands from iPhone via minijack and FSK-Arduino-iOS or via bluetooth/wi-fi.
Use some flight controller(idk which one) and some bluetooth/wi-fi board connected to it? Not sure if there is any protocol which I can use here.
Any suggestions?

>>893936
>So is there anything like in the 100 dollar range that does this?
No. 50-100m of range AT BEST is as far as you are going with 100-200$ pre-build quads with FPV.

>>894195
That looks like a bad idea. Can you put the ESCs anywhere else, like zip tied to the arm?

Where can I learn more about theory? I am interested if there's a book or other comprehensive material that explains it.

Also would like to get into GPS integration and devices that can be programmed and have memory.

So far I've got my eye on: Drone University by John M. Glover and Build Your Own Quadcopter by Donald Norris.

I like to challenge myself with random concepts, then I have to work out a solution.

This time I'm going to make my own pop pop boat but I thought I could give it a little remote controlled rudder (possibly solar powered with a small battery)

I have the servos and things to make the rudder but I've never really worked with RC stuff. Is there a universal remote I can buy to control my own things? And what sort of receiver would I use?

Just finished putting my first build together. I bought some carbon fiber props for it and they're slightly larger than all of my other props but I want to try to use them. Is this clearance going to be a problem? I imagine they'll give each other turbulence with the tips so near. Can I fly it like this? I have a whole bunch of smaller plastic props, I just want to try out the CF ones.

>>894664
I know you can do this with pixhawk/arducopter and mission planner using a telemetry antenna that hooks into your usb, but a pixhawk is $200 and not sure if there are cheaper alternatives

>>895446
can you explain your position more? I don't see how multirotors are actively infringing on fixed wings, if anything the general interest in multirotors will only improve fundamental tech like batteries and transmitters that will also help fixed wings

>>895518
The apm 2.5 is cheaper. You can get it on eBay.

>>895504
That won't be a problem. As long as they are not touching each other. There might be some turbulence, but it would be minor.

>>887776
Maybe the image is flipped?

>>895519
I'm not the guy you're responding to, but most old geezers are angry because multis bring attention to the hobby, from the media as well as politics. With that comes the danger of being collateral damage when regulating this Scary New Thing™, e.g. compulsory registration.

The funny thing is that all of this has happened before and all of this will happen again: When RC helis became popular, they were also discussed as being too dangerous (opposed to quads they actually have a kill count of 1) and shunned by some AMA clubs. If you visted multiple AMA clubs you'll sometimes notice that the heli pilots keep to themselves, it's a leftover from that era.

Umm, I guess you guys probably hate me but I'm new to all this so give me a break.

I just got done glueing a mount to the camera on my X5C-1 that allows me to quickly swap through a handful of different lenses.

Tomorrow I'm going to open the transmitter and install a "real" 2.4ghz antenna for more range.

Here's a short snippet of the first flight with a wide-angle lens fitted, I know the quality is shite but that's fine, it's only for fucking about.

>>895675
Have you actually gone out of range on it. Where i live I don't have enough room to fly line of sight and breaking the connection.

>>895688
A few times yes, it just drops out of the air beyond a certain range. If I'm going straight up that's not an issue, it just reconnects and flies again but if I'm moving horizontally it just plops down into a field

In this clip you see it climbing higher and higher then right at the end it cuts out. Signal was lost at that point and the little dude fell a good distance then reconnected and stabilised. The video itself didn't cut out but I had to trim it there to keep below filesize yet keep the cool flip.

This is beyond awesome, what was used for the frame?

I have a few helis and quads, this is my latest build

>>895857
Looks like they used steel rod and a TIG welder to build the frame, I don't have access to a TIG even though I know how to use them so I'm going to make it out of brass rod and solder.

I have a problem.

I have a CC3D Atom and I can't get it working. I can hook it up to my computer with USB and configure it, set the ESCs and everything then upload to the flight controller, but as soon as I do that it becomes an unrecognizable device and I can't connect to it again.

If I reload firmware by starting the rewrite thing and plugging in the USB cable while it's running, it'll find it and reset everything, but then I have to reconfigure and as soon as I save it again it stops working.

I tried using an older version of GCS and I used another computer to no avail.

This is frustrating... so close but I can't use my new quadcopter

Okay, I sorted the issue out... I spent 2 hours on it last night and an hour on it tonight, and the USB cable wasn't fully seated in the port. It's very snug and I pressed hard and it managed to click in a bit further and it corrected all of my issues there..

Now that I can fire the thing up I have a new problem. One of my motors is much faster than the others. I calibrated my ESCs at the same time and they're all the same model. I don't know what the problem is. Any suggestions? I've re-re-recalibrated it and nothing seems to do it. What am I missing? Is it because I'm using shitty chinese ESCs? I do have some new ones coming in the mail but I want to make sure I'm not the problem.

Anyone here ever made an RC scramjet (or at least anything RC & supersonic)? It's a grand project I'd like to do someday.

>>895957
>supersonic
How much money do you have?

>>896001
I know that, I didn't make a video of it and that was the only thing that shows how different one of the motors is. It engages at a much lower setting, and it runs much faster than all of the others. It even does it when I'm just testing things with openpilot.

Even at low throttle it runs faster than the others and it sounds like it goes faster than the others at max throttle. It's as if it's a different motor than the others, but my motors came in a set as well as the ESCs.

>>895982
I don't think it would be all that expensive as long as they were willing to strap a rocket motor to it and build a lot of it by hand.

Any of you guys have your radio license? I just realized I need to get one if I want to do FPV. There are no tests anywhere near me but there's one where my parents live in a few weeks so I think I'll drive out there to take it.

Now I just need to study. Anyone know of any good study guides online? I went looking and found many dead links to old websites and links to books for sale. I just want to study online.

it's definitely a scale rally car, so no massive jumps and super rough terrain. I like that about it, you have to think more than i did with my last RC car (point and shoot, bounce over anything more or less). I plan to mark out a scale-ish rallycross circuit somewhere on the farm i work at and have some fun.

Stupid question ahead.
I've got myself a cheap quad for a first 'serious' flying thing. After some time I've managed to kill one of the engines. Being noon I've started wondering if I could exchange all for motors for brushless equivalents, as a learning experience. Question is, will it be as simple as soldering engines to old cables? Or should I let dead drone and just go on and buy 250 chassis?

Fuck yes Group B.

>>899647
I swear, writing posts on smartphone without physical keyboard is a recipe for disaster.

And yeah, as far as I understand engines are cheapish brushed ones. One that failed did it after circa four hours of flight time. Already ordered spares.
So this leads to the main question - is link related good product to buy and build on? I, as glasses user, will rather stick with screen for for but is the flying platform worth its price?

More or less finished the XV01... Stickers all finished last night, just got to sort out the body mounting proper. It sure isn't perfect but from 6 foot up in the air when it's sat on the floor it's easily good enough.

I really enjoyed it, it's been such a long time since I did model stuff but daam it's satisfying. Took me a week of evenings more or less to do this one, got my moneys worth already, I don't even need to drive it and it's been worth the money.

heh, that wide wallpaper

Can someone help me find the best FPV set on banggood? Excluding monitor.

I am kinda doubting between 200mhz and 600mhz. 200mhz might not be powerful enough and 600mhz seems a lot of overkill. Shame they dont have anything in between. Also I keep hearing about transmitters overheating, so what is the best FPV set for around 50 bucks? Preferably lightweight camera and transmitter ofc.

like this set for example:

http://www.banggood.com/Eachine-700tvl-13-Cmos-FPV-110148-Degree-Camera-w32CH-Transmission-p-974874.html
http://www.banggood.com/Eachine-FPV-5_8G-32CH-Wireless-AV-Receiver-RC832-p-975426.html

but it seems to get really hot and then cut out after a few minutes, also the cam doesnt seem to be really good and it probably needs better antennas but hey what do you expect at that price

so anyone got an alternative?

>>900623

oh gearbest or something is fine too, i rather buy everything at once though since i also wanna buy a Cheerson CX 20

I have been looking into wifi spy tanks (little tanks with cameras that connect to your wifi so you can drive through your house from everywhere) but for 60 bucks i think its kinda expensive.Is there any way to make one yourself? And then im mostly interested in the controlling parts, electronics and app, not the driving and mechanics

>>900639
I found this one for 30 bucks

http://www.banggood.com/RC-Car-Tank-777-270-Mini-Wi-Fi-Camera-Support-iPhone-iPad-iPod-Controller-p-977225.html

but i am a bit unsure of it since i cant find it but is it only available for iphone? i have android myself, and i would like to use a windows pc for it too.

and does it only work when im on the same wifi network? or can I drive this thing in my house from everywhere in the world where I have internet connection?

>>900976
oh it does support android

but my other question still stands, can i control it from anywhere or do I have to be on my home wiif network?

Nigga how the fuck do you think you're controlling 4 separate engines with a single throttle and joystick?
That's right, you're not. You're sending "I wanna go left lol" to the computer and it does the maneuvering for you.
"Acro" or whatever just eases up the tolerances a bit. It's like when your mom puts her brand new TCS/STC/ABS/ESC/WTF Volkswagen in "sport mode" to "be a little crazy" when grocery shopping. All that happens is that some values in the car's computer change from 1.0 to 0.4

>You're sending "I wanna go left lol" to the computer and it does the maneuvering for you.
The first hobbyist multicopter was controlled by 4 heli gyros.
http://rcexplorer.se/projects/2010/03/the-tricopter-v1-and-v1-5/
Tell me then, how does it do more computing if it is made of the same components a heli uses?

>"Acro" or whatever just eases up the tolerances a bit. It's like when your mom puts her brand new TCS/STC/ABS/ESC/WTF Volkswagen in "sport mode" to "be a little crazy" when grocery shopping. All that happens is that some values in the car's computer change from 1.0 to 0.4
If the are only software changes, why can I fly in acro mode with only a gyro - I can litterally unsolder the other sensors and it works - While other modes like leveling, altitude hold or position hold need an accelerometer , barometer, and GPS respectively?

>>905320
i saw a fun rc heli with an gyro at a toy store, is it worth getting into?

>>905626
>The first hobbyist multicopter
>I think internet = real life
People have been building these since like the 80s, maybe they didn't write blogs about them, maybe because they were pretty shit until modern micro controllers and gyros. Notice how nobody gives a shit about his "first" in the videos.
>how does it do more computing if it is made of the same components a heli uses?
Obviously because there's 3 rotors all stabilizing each other you retard, also notice how an experienced RC pilot is limited to slow and basic maneuvers, nothing like the fancy pre-programmed flips you see everyone and their dog do with the store bought ones.
>why can I fly in acro mode with only a gyro
You can't. You've got 4 gyros connected to 4 micro controllers. Again how the fuck do you think you're controlling 4 separate engines with a single throttle and joystick? That's right, you're not. Meanwhile you can buy purely mechanical Helicopters

>>905632
The helis sold in toy stores instead of dedicated hobby/RC stores are almost universally shit. You're looking at at least 300$, also, gas powered is really the way to go. The reason you can buy "decent" quads in toy stores is because, as mentioned they're 90% self flying with all the software on them. Even if the weight distribution is off and the blades are misaligned the software will simply take care of it.

What is the lowest safe voltage per cell on a 4s lipo? More specifically a 4s, 10c, 10,000 mah multistar lipo.

I built a fixed wing fpv but I'm unsure about the safe voltage limits on these batteries, I usually don't go below 3.8v per cell but I heard that you can push batteries lower if they have low discharge rates, like the 10c.

>>905778
While I'm arguing about how they behave, you seem to be arguing about the fact that there is a computer in it and how that's a bad thing, because it can't be understood and leads to unpredictable behavior.

But the "compute what to do with motors from stick inputs" part actually not very complex for flight modes that don't hold level, height or position. It's not like a desktop OS with millions of lines of code and thousands of states the system can be in.
It can be understood by a hobbyist and I don't think it requires more time than getting a mechnical heli to fly correctly if you start from scratch with both.
For cleanflight for example:
The stick positions you are so enamored wit go in at line 115/116: https://github.com/cleanflight/cleanflight/blob/master/src/main/flight/pid.c#L115
And by line 208 we know how we want the motor outputs to change or not (axisPID), which is in the same 1000-2000us format you use too. The only thing left to do is to multiply it with how the motors are currently set and add the throttle to it, which happens here at lines 749-759: https://github.com/cleanflight/cleanflight/blob/8402f4512a913abde32ccec704704fc466516997/src/main/flight/mixer.c#L753

Tada, magic! Hell we're multiplying, addding and substracting shit here. Even if you don't know the programming language it makes sense because it looks like math - because it fucking is.
Of course a computer does it more quickly that I ever could. But it only does what it is programmed to do. It is a tool. I wouldn't be able to switch power on and off as quickly as you need to to run a brushless motor either.

And the time used to understand it is offset by the time saved because I don't have to repair swashplates, as the device is much simpler mechanically.

[cont...]

[...cont]

And yes, I agree it becomes more of a clusterfuck if you add behaviors mechanical helis can't do, which depend on other sensors like a GPS.

That being said, the bullshit an ESC of a brushless motor has to go through to sense the current position of a sensorless rotor and commutate it is also complicated. Read this for example: http://www.st.com/st-web-ui/static/active/cn/resource/technical/document/user_manual/CD00236524.pdf
So I sure hope you're not using those - but judging from the pic you posted you do...

I know but I am looking to get back into flying but I just can't come up with a way of beating their price on shit. It seems economics of scale is really starting to go with them (like a simple pre built cheap computer vs building your own).

$499 right now for the standard model on sale now (slickdeals.net)
2.7k video that is a sony sensor (seems better than current gopro).
1 km 720p FPV, follow me.
Was wondering how they are doing Waypoints though (have to fly first then repeat, guess this is how they comply with rules).

I am trying to come up with something better and cheaper but with all that stuff I really can't off the top of my head (especially that nice FPV video).

>no servicability
How so?
>With the P3 the ESC's are built into the main board.
Oh....so this?

Anyone have any other ideas?

If a quadcopter is flying a waypoint is there a way to hijack it through radio signal and control it manually?

There is a set of waypoints W, where each distance between them is at least 200 meters.
A quadcopter is programmed with set W and as manual input it takes its position W1, and destination W2. It is capable of calculating/approximating the angle and distance between W1 and W2, and when ready to fly, it will hover till programmed height H, side to appropriate angle and fly to destination and land on W2.

That's my idea and I'd like to build that system. I think that this set up doesn't need radio components but I am unsure how consuming are programmable boards? I don't have experience with embed systems, any tips for building a programmable quadcopter?

>>890350

Off the top of my head but you don't even need to program it that way, software and GPS will handle the rest.
>>907212
Fake a gps signal in theory but you would have to figure out where it is going (coords) or observe the movement of the multi and adjust your fake coords to compensate.

Anyone got any personal recommendations for directional receiver antennas working on 1.2GHz? I need something with stupid high gain and not really that wide of a beamwidth.

What's a realistic max flight distance from point A to point B for a really stripped down quadcopter?

Tell me 60 miles is virtually impossible without dumping thousands on batteries made of fetus bone dust.

>>886340
been trying to decide.. plane or copter. i have done copter before but i think planes might be more fun. only thing is i have zero experience with planes... whereas quads are easy to do

>>906959
is this 3.3V for planes too?

>>908202
The lighter you are, the more you are going to be buffeted by the wind. Efficiency scales with propeller size, but your top speed will likely suffer with larger props. Assuming you aren't likely to break 70mph, and with a generous flight time of 30 mins, you are looking at less than 30 mi. But, you also need to be able to broadcast your signal that far, unless you are giving it a routine to execute. Realistically, 10 miles is a good target. Do you need to go that far? 10 miles in a straight line is quite far.

Well, I bought it. It's only 3 hours drive away. Almost tempted to drive there myself. Should be here in a couple of days if I'm lucky.

Say's it's 4WD how does that affect drifting? Traditional drift cars are RWD, right? Or is it adjustable or is necessary when you scale a car down?

>>912114
NICE.

>>912114
i'm not the anon you quoted and keep in mind i've only ever rc drifted round the corner of my bed a couple times, but the impression i get is that there's 50:50 4wd drifting at the easiest end, then as the drive ratio is shifted more to the rear (with gearing so rear turns more per rpm than the front) it gets more skilled and requires more countersteering (more like a drift car) until eventually yep there's full RWD cars.

Opinion of Stingray 500? Mine's a piece of shit and while I'd love to learn to fly it (more than just hovering in place), it keeps fucking crashing because CY's retarded hardware malfunctions a good 30% of the time.

There's a fuck load in whatever scale model trains and slot cars use but it's all way small for RC cars.

I saw one dude made some armco out of thin sheet steel he bent into shape which looked awesome but was time consuming and needed a good way of folding sheet steel.

I planned to make some out of pipe cut lengthways and opened out on itself but when it came down to it the short days and amount that would have needed doing fucked that idea off.

For road markings and signs I think you gotta make 'em yourself, but they're easy.

Quad fly because of software, so what? Your helis are only flying because people spent hours and hours getting that design to work.

>>910505

Yes, they are faster.

You got him there, RC helis are ridiculously expensive

>more maneuverable
RC helis, hands down.

>you actually control it
Acro mode /feels/ different, and a vast majority of commercial quads don't have it.

>more fun
To each their own. Fun fact: You can also FPV on a heli.


>>914034
>$100 to repair it
Only if you're a shit pilot who didn't learn to fly on a sim before doing the real thing. You really think that every outing ends in a crash?
Toy store helis are pretty shit, I agree. You're looking at products that were shit out as cheaply as possible to ride on the hype instead of redesigns of redesigns of redesigns to make the thing /work/.

>>914044
>Yes, they are faster.
Doesn't really make sense anyway, quads are fast enough for any purpose, and the fastest quads are going ridiculously fast.

>RC helis, hands down.
3D CP helis yeah, any basic quad will outmanoeuvre basic helis.

>Acro mode /feels/ different, and a vast majority of commercial quads don't have it.
Currently flashing my micro to get the acro mode. Anyone serious about multirotors will end with acro mode (except if he's dealing with 5000$+ rigs)

>To each their own. Fun fact: You can also FPV on a heli.
How comes I've never seen a cool FPV video of an heli? There's a plenty of quads and fixed wings
But yeah, to each their own indeed. I was arguing against the guy that thought quad shouldn't even exist because nobody can fly them without a gyro. And cost is very important, I've read a lot about cheap helis but in the ends it cost way more than buying good quads.

>>914051
>quads are fast enough for any purpose
Moving goalposts.

>basic quad will outmaneuver helis
I'd say that this is not much of an argument on the grounds that you can't really compare two cheapshit products of any kind with any real results.

>never seen a cool FPV video of a heli
Very simple reason: Most RC heli guys are older or last generation, so they just take joy in flying the thing and watching from where they stand. Quads are a relatively new thing, especially in the hobbyist category, so you're going to see a lot of younger people say "that looks cool, I want it" and those are generally the same people who want to document everything they do with cameras. There are some (well, a lot) of younger heli pilots and some older quad pilots.

It also boils down to "it's for a different purpose". Often, FPV quads will have autolevel and other features to make it more user-friendly so the pilot can just fly around and record. Helis are generally, from what I've seen, more "show-off" things; flying FPV while trying to do the tricks that are usually done would get you dizzy fast, not to mention losing orientation unless you had a shitton of telemetry telling you your direction and such.

>cheap helis are more expensive than good quads
Yeah, seems like it. I'd say it's because it's a hobby market, and like any hobby market they can charge out the ass and people will still pay. Helis also tend to have more moving parts.

>>914056
The majority of FPV footage on youtube is from custom quads in acro mode. (I'm not sure anyone's doing FPV in autolevel)

As you said people have to be flying helis differently than quads. For example I really love doing exploration with my quad, going in some remote place and flying the quad around trees.. It's really fun and watching the video afterward is too.

I think warp-quads (very high power:weight ratio, no camera or anything) are the closer to helis, just doing tricks and awesome things in the air.

So yeah, not sure I'll go with helis one day. I'll probably try rc cars and fixed wings though.

>Yeah, seems like it. I'd say it's because it's a hobby market, and like any hobby market they can charge out the ass and people will still pay. Helis also tend to have more moving parts.

They're great because of how simple they are mechanically.

>>914051
>How comes I've never seen a cool FPV video of an heli?
https://vimeo.com/38322747
Now you have.

But really, a major reason is that it's a lot harder to get the rotor disc out of view with a heli than a quad, and vibrations are often a problem with helis.

Helis perform much better from an aerodynamic standpoint, but it's hard to beat the adaptability, robustness, and overall grab-and-go appeal of a quad.

And for the record, I enjoy flying both, as well as all manner of fixed-wing models.

>>914305
>https://vimeo.com/38322747
Ah saved, can't watch it now. I never really searched before, I'm a dumbass.

When I'll be rich I'll get a badass heli.. or four badass quads.. argh.

Anyway, show us a pic of your heli!

>If you're in the US, though, it's illegal to fly multirotors commercially without a Section 333 exemption (you have to have at least a sport pilot's license).

You must have a sport pilot's license to operate a UAV? If my company gets a Section 333 exemption, do the employees need pilot's licenses?

>>914580
>You must have a sport pilot's license to operate a UAV?
For now, yes. Technically a sponsored RC pilot can't even win prize money for an aerobatic contest legally unless he has a pilot's license (for manned aircraft) and a 333 exemption. It's fucking ridiculous, but the FAA seems to think doing something ridiculous in the mean time is better than doing nothing at all.

I'm hoping the final rules for commercial sUAS operation are much more reasonable.

>>914580
>If my company gets a Section 333 exemption, do the employees need pilot's licenses?
Yep.

>>914595
As someone that lived in California and watch a fire hinge on 'contained, not at all threatening' to 'we're fucked' because some ass hat was flying in controlled airspace without communications... And this has happened over and over again... Fuck drone 'pilots' in the ass with a BBC in pound me in the ass jail.

>>914627
Surely piling restrictions on law-abiding drone pilots will help bring these irresponsible yahoos in line, right?

Yeah, no. Fuck you. And fuck Cal-fire too, for letting California burn over a few fucking knuckleheads with drones. Even if it IS flying where it shouldn't be, it still only poses about the same threat as a large bird, and pilots have tolerated that risk since the fucking dawn of aviation.
>Inb4 bias accusations
I'm a private pilot too. Their rampant abuse of TFRs over the last decade pisses me off just as much. Goddamn firefighters are too damn full of themselves these days.

The FAA just made a move on UAS registration.

http://www.theverge.com/2015/12/14/10104996/faa-drone-registration-register-february-19th

Looks like the registry is going to be opened on Dec 21 for individuals and sometime in the spring for a commercial registration.

>the website said registration is free
>the transaction authenticates the user
This sounds like one of those "Input your CC# so we know you're over 18, we totally won't do anything bad with it, promise!" scams.
And if it's just to "authenticate" the user, why charge every 3 years? Did the user suddenly turn into a new person?

Fuck this.

>>915019
Are you really complaining about a $5 registration fee that comes up every few years?

You need a new hobby if that kind of money is going to break you.

We all knew it was bound to happen. It doesn't appear to be as restrictive as many said it would be, more so for the purposes of identification. I have no trouble with it.

>>915022
Yeah, I was thinking the worst that would happen is we would have to start building transponders onto drones along with registration.

I wonder if this has any impact on FPV or commercial applications. Will I still need a pilot's license to operate one? Will FPV ever be legal in the US? It's my understanding that you still need line of sight, right?

>>915022
>It doesn't appear to be as restrictive as many said it would be, more so for the purposes of identification. I have no trouble with it.
Yeah, it's a hell of a lot more reasonable than what I was expecting.
I still find it ironic that they require registration for a half-pound model airplane, but not a 250-pound manned ultralight, though.

>>915036
>but not a 250-pound manned ultralight

That's probably because the pilot will be around to answer for it if they fuck up, and the pilot already has to be registered themselves. With RC, the pilot could take off and no one would know who caused the accident.

>>915022
>The registration rules also require that they be part of an "unmanned aircraft system." An "unmanned aircraft system" includes the communication links and components that control the small unmanned aircraft along with all of the other elements needed to safely operate the drone.
So free-flight is exempt, regardless of weight?
What about an F1E model with a heading-hold autopilot?
Or by extension, a more advanced, fully-autonomous UAV with no communications systems whatsoever?

To me, it seems like "communications links and components that control the unmanned aircraft" would serve to reduce risk, not increase it.

>>915051
You can't have any control systems on it whatsoever. If it's anything similar to the rules around amateur rocketry, you can't even have computer aided stabilization onboard without it being considered a different type of aircraft.

>>915054
>If it's anything similar to the rules around amateur rocketry, you can't even have computer aided stabilization onboard without it being considered a different type of aircraft.
Huh? I never saw anything of the sort in Part 101.

>>915066
Maybe you should look under Part 121.

http://fas.org/spp/starwars/offdocs/itar/p121.htm

>>915075
Also, reading into it more I think if the rocket has a built in recovery system it doesn't count. And active stabilization doesn't make it count either, only active guidance.

I figured active stabilization would be enough, because older missiles had nothing but that.

>>915075
>ITAR
ITAR is export controls. It has nothing to do with how a model rocket is regulated within the national airspace.

Now, if you launch it across an international border, that's another story...

Personally I can't wait to hear stories about dumbass bros getting fucked by the FAA because they didn't register their DJI Phantom or whatever.

>>915818
they're marketing it to the military so they can afford expensive components. Also, the battery times may be exaggerated.

Why are small helis much more expensive than quadricopter (for example)?

There's only two motors etc..?

>>915818

Parts are probably expensive as fuck, and the battery life is almost certainly under optimal conditions (likely just hovering in still air).

>>916069

Quadcopters hit "fad" status, hardcore. Competition drove down prices to previously unbelievable lows.

Helicopters didn't enjoy the same surge in popularity, remaining a hobby item. And, like all hobby items, a fairly inflated price.

>>916071
Indeed, even rc cars are expensive compared to what you get for 20$ in a quad.

They're the size of my 250, I was thinking about something smaller, something that could fly indoor.

>>916907
I only have the quanum 2, but a few people who had fatshark said the quanum are better for immersion than some fatsharks (and there's no such thing as cheap fatshark)

how would you rank these motors in terms of quality and price to performance? What would be the best option if i just want to fly around doing fpv (no expensive equipment) with my 470 size quad?

quanum
multistar
sunnysky (x series)
tiger motor
avrotor

are there some other brands worth looking into?

>>917125
You could shorten the arms on David's tricopter, but otherwise there aren't really any kits. If you want something smaller, you would have to design it yourself.
and on a small build, you won't have a lot room for the tricopter mechanism. Weight might also be a problem.

>>917230
As far as quality goes, avroto and Tiger motors are top tier. Quanum and multistar being bottom tier, and sunnysky being in the middle.
For a 450 build, that doesn't need to carry expensive stuff, they will all work equally.
As for the sunnysky motors, most of the listings on banggood and ebay are fake, just so you know. I flew some fake sunnysky motors on my quadcopter, but there are no thust data on them. So I'll probably build a thrust stand to test them out.

If you are going to build one yourself, you can make it y6.
And if you still want a traditional tricopter, you can look at the picture for inspiration.
The mechanism is from a nonacopter (9 motors), which a guy built, it looks pretty good.
Here is the video about the yaw mechanism

And here is the nonacopter flying.

>>917313
Well that's cool.
>even with 9 motors it's not that reliable
Ha

maybe in the future I'll build small Y6.. or maybe a v-tail with brushed motors, that'd look cool if I knew how to make a frame.

>>917323
Frames for brushed motors, are a bit more simple, since they are a lot less stressed when flying, that is why you see frames 3d printed or made out of acrylic.
I might try to build a tricopter with brushed motors. It sounds fun :)

>>917332
Brushed are fun, they're just a bit frustrating when they get broken too fast, and you see it comming. First the motor's a bit stiff, then it's weak, can't start without help then doesn't respond. I'm sure it's easy to fix them but I don't see how. At least they're cheap (if you don't buy the mmw ones)

>>917323

Supersonic model rockets are a thing, that's probably a better way to go. The fastest RC models I'm aware of are large slope gliders reaching the upper 400 MPH range. There are also some very fast turbines that aren't far behind, but the vast majority top out at 200 MPH in accordance with AMA and field restrictions. Going faster is playing with fire - not even full-size aircraft are permitted to go faster than 250 knots below 10,000'.

I recently finished my quadcopter. Running 5 inch on 2633kv motors. I only flew it for 1 min, because I broke a prop when I tried to land it, and I had to go to work. It was really stable for the 1 min i flew it. Which is surprising since it has a 1:7.5 weight to thrust ratio.
It is running betaflight, and so far I really like it.

>>918336
are those temporary landing legs?..

>>918624
Yeah. The battery isn't really protected in any way, so I am using these. I will 3d print something, after Christmas, when I have access to a 3d printer.

>>886341
I shop GensAceUSA for the most part, especially for high-discharge applications. Gens-Ace, Hyperion and Thunder Power all seem to have batteries with exceptionally low internal resistance, and Gens-Ace is the most reasonably priced of the three. Haven't had very good experience with Turnigy batts, so I don't usually order batteries from HK.

Recently I've been considering making my own pack out of li-ion round cells (e.g. Samsung 25R) for low-discharge usage. Some of these newer ones designed for E-cigs actually achieve respectable burst discharge rates, and they've got about 50% more energy density than Li-pos.

>>893936
Hello guy! My name is Anon and I have an answer for you.

The answer is below this sentence:

No.

Thanks for the question! bye bye.

spent 3 hours searching for my quad that flew away (not even far) because the video feed cut off, because the stupid connector disconnected.
Found the quad, lost my 200$ fucking glasses while searching the quad.
Came home to my charger not starting up..

Fuck.

>>919356
>lost my 200$ fucking glasses while searching the quad.
How does that even happen.

>>919430
running at night through vines with fucking branches, one must have hit my glasses, didn't notice I lost them, because well it was fucking dark.

glasses are stupidly expensive too, lost the one adjusted to my sight, so everything's blurry. What a day (just spent 2 more hours searching for them this morning)

I've been doing a bit of research and I want to get into building my own Quadcopter. Money isn't exactly an issue - I just want something that's relatively simple so I can gain some experience. Any ideas? I don't have any experience in soldering (I know how to use a solder, but never applied it to anything) or making electronics

>>919934
what size quad do you want to build?

>>919940
250, most likely. I don't want a tiny drone desu - are the bigger ones more expensive? I'm looking to build something with a camera if possible

>>919943
i personally like around 450 size, easy to work with and they can carry some cargo. also 450 is about the biggest at a reasonable price, building a 600+ sized one would begin to cost quite a bit.
a 250 sized quad could carry a camera and fpv equipment but it can get quite tight in there, thats why i like 450 sized more, you can use bigger recievers, flight control boards, cameras and that kind of stuff.

>>919945
What size drone is that? It looks pretty small. I have big hands, so I think it would be impossible to build small quads.

What supplies/software do I need, parts aside? i.e. Solder, soldering wire, quad calibration software, remote control itself, etc. ?

that is a 250 sized quad, pretty tiny isnt it?
the main things you need:
Transmitter (turnigy 9x)
Receiver (turnigy 9x compatible)
Motors
Propellers
ESC's
Battery
flight control board (such as a kk2, naze32 or something like that)
I have been behind in the multirotor scene, so i wont give any advice on what parts to buy (except the turnigy 9x), but there are a lot of little things to consider like connectors, locknuts for propellers, power distribution board (or a bundle of wires soldered together), servo wire extensions, heatshrink, BEC (if esc does not have a built in ESC).

>>919952
Here's what I have so far in my cart.

>Frame
Turnigy Talon Carbon Fiber quadcopter (498mm)

>CW props
GWS style slowfly propeller 8x4.5 (4 pack) x2 (spares in case I break any)

>CCW props
GWS style slowfly propeller 8x4.5 (4 pack) x2 (ditto for CW props)

>Motors

>>919988
>>919952
Forgot to add; is there anything I still need or I'm missing? I have nothing else at all, no soldering equipment, tools - nothing.

>>919996
You need a battery, Transmitter, Receiver (Usually comes with the transmitter), Charger for the battery, and a flight controller

>>920001
Forgot those, crap - duly noted.

>flight controller
Is that the brains of the whole quad? Does it also double as a power distributor(?) or does it depend on the model?

>>920003
The flight controller is the "brain" of the copter.
Almost none of the current flight controllers have an integrated power distribution.
Some of the controllers I can recommend is:
>naze32
This flight controller is usually seen on racing quads. I can recommend flashing betaflight on it.
>Ardupilot/Pixhawk
The apm and pixhawks is a flight controller, which truly make your copter autonomous. You can attach a GPS to it, and have it fly to waypoints. This flight controller is used in mapping, and aerial photography.
>KK2 board
The KK board is a REALLY simple board. It is what I started with on my tricopter. Really simple board. I flashed it with firmware made by RC911 from rcgroups.
>CC3D
My friend is flying a copter with CC3D and openpilot, should also be pretty simple. Betaflight/cleanflight can also be flashed on this.

>>920018
I saw a guide where someone built it with a CC3D board. I just want a board that's easy to use for a first project.

General question - do hobbyists make several different R/C vehicles or do they make one of each kind (car, boat, heli, quad etc.) and then just upgrade it? My thought process is whether I should do an easy build then make a really good and expensive proper build

>>920018
Also, what's the sweet spot for battery weight and capacity? I don't know if it's worth getting a 5,200mAh battery for the extra amperage and adding more weight or sticking to a 2,400mAh battery that weighs less.

For people that attach a camera to their quads - how do people choose to display the video? I've seen people use these Oculus-Rift looking glasses that receives from the drone, but are those expensive? Are they good?

>>920023
It sounds like this is your first multicopter. If so I can recommend buying a hubsan or a syma x5. Since these things are indestructible, and cannot hurt yourself or other people.

>>920029
B-But these are pre-built - what's the point? I own and know how to fly a quad, I want to move on to building one

>>920031
I recommended you a hubsan, IF this was your first multicopter. If you actually know how to fly them, then yes there is no point in buying one.

>>920032
It would be my first multi which I'm building, hence all the questions.

>>920028
>battery
I think 5000mah would be good. It looks like you can run 4s. I am not sure though.

As to seeing what the camera is seeing on your quad, you will need:
>Video transmitter
There are multiple frequencies to choose from. With 5.8ghz being one of the more popular frequencies, since it is legal to transmit on that frequency in most countries, and offers better video compared to 1.2ghz or 900mhz.
>Video Receiver
For the video receiver, you just need something which matches your transmitter.
>Goggles/monitor
For the "Oculus-Rift looking glasses", there are a couple of options, the cheap option being just a cheap monitor. There is also the quanum goggles(http://www.hobbyking.com/hobbyking/store/__78129__Quanum_DIY_FPV_Goggle_V2_w_5_inch_LCD_Monitor_Kit_EU_Warehouse_.html?strSearch=quanum%20fpv), which is just a monitor in a foam box, and for the expensive option there is fatsharks. Fatshark goggles, are quite popular because of their size. Some of the models even have an integrated receiver, and DVR, so you can record what you are seeing (This is more useful, for racing quads, which don't have the space for a recording camera.)

I can recommend reading through Oscar Liang's blog. He has a lot of information about most of the things regarding multicopters. Most of it racing related, but there is a lot of information for beginners.

Those are the ones I saw. They're pretty expensive, though. Can you build in a camera + transmitter without making use of it? i.e. make the quad video capable, but not use the video?
>inb4 it uses undue power

I'll give the blog a read - thanks.

You can actually do it, but I am not sure how reliable it is. http://rotorbuilds.com/build/42
I can only recommend doing it the traditional way, since I do not know anything about it.
>4s
4s is 4 cells yes, I found some thrust data on the motors, and they seem to work on 4s. 3s might be better for a beginner, and then you want more thrust you can buy some 4s batteries.

Thanks for all the help - it's been invaluable to me.
I'll start off with an easy 250 kit (Emaxy nighthawk 250 skyline32 Acro kit) which seems to need little to no soldering. I'll still need to buy a battery and a transmitter + receiver.
What transmitter do you use/recommend? I was thinking of a FrSky Taranis X9D

I am currently using the flysky th9x, with a frsky module installed. I regret not buying the taranis, so I do not think you will be disappointed.
My friend is flying with the same equipment as that kit. It flies pretty good. I would rather buy a zmr 250 kit, since this frame is really popular, and finding replacement parts is a lot easier.

As for batteries, the ESCs can only handle 3s, which is fine. 2200mah 3s would be a good start, then you can move down in mah, to increase speed by reducing weight.

I second this. Thinking of putting a motor in a go kart, brushed or brushless doesn't matter but what kind of speed controller would be big enough? and where could I get one in australia?

just build it and fly it. dont fuck around with those toys, do i the manly way. its not that hard really, i just built my first rustbucket of a quad, went out on a little field with a 4 lane road to 1 side, trees to the other, and power line above. everything went smoothly.

hobbyking. look at the motor rating (amps and voltage).
also it is very easy to burn out an rc motor and they need good cooling, so be careful.

i suggest looking into hobbyking b-grade batteries, they have like 6s 5000mah batteries for 30$, probably wont last long but in a go cart where you need a lot of power might be good.

I'm gonna be the best one day /RCG/. One day.
