Man, FUCK C-clips.

Now that the Racerstar RF series has been discontinued, anybody know of any other cheap motors with retaining screws and hollow shafts? The cheapest I can seem to find now are DYS SE series at $50-60 a set.

Alternatively, you think I could just trim and tap the hollow shaft of something like a BR2306 or Kingkong GT2205 to take an M2 retaining screw? Or would the hole already be too wide?

I've been super impressed with my (original) 4k Yi, especially the battery life compared to GoPro - it can record just over 2 hours at 4k 60mb/s with the screen on (though I generally shoot 2.7k with the lens fisheye correction enabled).

I have a handheld Zhiyun gimbal for it too which is great, looks like the one you have is Zhiyun as well? I had to 3D print a new part for the Tarot gimbal on my big quad though otherwise it's about half a mm too small for the Yi, unlike all the Zhiyun ones :/

>>1197701
I'm going to have time testing it all this weekend.
I just came back from testing it a bit. I ghettod a gopro mount onto the car, but the actual gopro screws didn't hold up.
Have already ordered some better mounts.

But from what I've seen so far, very impressed, it's silly that it's in such a small body.

And yes, it's the zhiyun rider M.
I think I have to diy a bit too to center everything nicely.

Do you have any footage from that setup?

I've not actually tried the EIS on mine, but I am curious how it behaves in addition to a gimbal. A guy I follow on YouTube has been doing some experiments like that though;

How the heck can this robots accelerate and stop in a fraction of a second like they have no momentum? Do they have some kind of suction fan that keeps them attached to the ground? Magnets?
Also, what kind of motors do this robots use?

My university houses a robot competition and one of those robots could easily win all the competitions, but I need to figure how do they work besides asian magic.

>>1197854
Depends on the rules/class/etc. I think in that video the ring is steel and rubber, so they use both magnets and tire traction to move so quickly. I've seen suction fans in stuff like line-followers.

Hello Fellows i have a motor controller and it is older, says NiCd or NiMH in the manual can i use lithium Thanks in advance

>>1197879
>they use both magnets and tire traction to move so quickly
That explains it. My university allows anything below 1.5 kg and 30cm^3 of volume, only controlled by arduino, more advanced stuff like artificial vision isn't allowed.
I initially bought servos, but i think they're quite slow.

The competition will begin next year, so I have all sumer to work on something.

Real servos are boss mode. Cheap toy servos are shit.

https://www.youtube.com/watch?v=rA6yrZrxuPs

>>1197894
Yes, but since there's no LVC you'll have to be careful not to overdischarge your batteries. At minimum, set a timer, or better yet use some sort of voltage alarm or indicator. These little guys are cheap, work well and have a loud alarm that goes off at a configurable voltage: https://www.youtube.com/watch?v=a4gv3FFoTpY

Also, of course, you'll have to ensure that the battery you use is within the ESC's allowable range (or at least close to it). So if the ESC can take up to 6 or 7 cell NiMH, you should stick with no more than 2 cell LiPo.

One last thing, if the ESC is that old, there's a fairly strong chance it's a brushed ESC, as brushless motors and ESCs were not very common back in the NiMH days. Just something to be aware of.

New to the hobby... Just put together my first quad today, at least enough to fly it. I need to secure the camera, it's just vibrating around in there for now.

Planning to nix the zipties over the ESCs in favor of electrical tape, and add a buzzer. When I go in to add the buzzer, I may remove the connector from the receiver and just solder the wires in.

is there a way to tell if an action camera can output live video through its output plugs while its turned on? or is it safe to assume that most don't with the exception of gopros?

i was thinking of maybe using this as an fpv feed
https://www.jbhifi.com.au/cameras/video-cameras/kaiser-baas/kaiser-baas-x90-action-camera/984438/

i bent a motor shaft. what do i do now?

>>1198907
The mobius can do live out, Hobbyking makes a shitty "dock" with fpv transmitter for it. However, you'll get a lot of lag.

https://oscarliang.com/best-fpv-camera-quadcopter/#use-hd-camera-as-fpv-camera

>>1198935
>However, you'll get a lot of lag.
This issue is pretty much irrelevant now. Might want to reevaluate your attitude towards action cams for FPV. The Hero 2 was pretty awful lag-wise, but the OG Mobius was flyable at only a tenth of a second of latency. And newer generations of RC-oriented action cams like the Mobius 2, Mobius Mini, Runcam 2, Runcam 3 and Split all have virtually nonexistent lag (about 1/24th of a second, corresponding to a single frame).

i know how to design my own PCBs and make my own all integrated esc's,fc's etc (i'm an electrical engineer)

>>1198907
>or is it safe to assume that most don't with the exception of gopros?

All of the action cams I've owned do video output (GoPro 3, Yi, Yi4k, SJCam M10) so I'd say it's safer to assume that most _do_.

Is it a bad idea to share the 5v from my flight controller with video and rx? FC has 5v out for receiver but since FC and the all in one ESC self regulate I have no PDB. Should I find a way to devote a seperate source for each? Will rx signal (noise in power line) mess with the video tx?

>>1199254
The 5V regulators on most FCs are only designed to power the receiver & aren't powerful enough for VTX/cam as well. There are some exceptions, like the Radiance FC from Furious FPV (2A 5V regualator), but you'll want to check your FC.

You can get tiny standalone regulators for 5V/12V, I like these Matek ones;

https://www.banggood.com/5V-12V-Adjustable-Voltage-Dual-BEC-Output-Board-Only-1g-p-1031884.html?rmmds=search

>>1199282
Had a feeling that was the case. Good thing I already bought a Matek Systems Micro BEC 5V / 12V Adjustable Buck Module. Should have bought four.

>>1199254
>Is it a bad idea to share the 5v from my flight controller with video and rx?
Depends. Which FC are we talking about here?

>>1199282
>The 5V regulators on most FCs are only designed to power the receiver
Not really. The FC itself usually draws more (~100 mA) than the receiver does (closer to ~50 mA). Ratings on FC-integrated regulators I've seen range from 500 mA to 2 A. Only the upper end of this range will be able to adequately power thirsty external components such as VTxs or servos, but they are out there and aren't terribly uncommon.

And for reference, a TX02 camera+200mW VTx combo draws about 400 mA at 3.7V, and presumably a bit less at 5V.

Cicadias are boss ESCs. Put 'em to good use.

On a related note, I'm considering a super-light 4"-5" 6s build using the Cicada or DYS 30A 4-in-1, both of which are rated to 6s. Anyone know of an 1806 motor that could potentially survive on 6s?

>>1199675
it is my understanding that pancake shaped motors handle more voltage and are lower kv and its the opposite with narrower motors. 1806 seems awfully narrow

>>1198060
Thank you

>>1199254
You could get a 12v camera. All that means is it has a built-in regulator. It'll work for seven volts and up.

>>1199828
Even better to get a VTX that takes LiPo voltage & outputs 5V for the camera.

Speaking of cameras.

Are there 120fps cameras?

I want something really tiny solely for the purpose of recording tires, don't need higher than 720p.

>>1199834
Most of the current generation of action cameras have 'slow mo' modes that record at 120/240fps but they aren't that small in the grand scheme of things.

should i dip my 3.5mm motor shafts in epoxy to increase their diameter slightly? that way they might then fit a 4mm prop adapter.

>>1200194
Heatshrink would be a less risky solution, assuming you can't just find spacers like the rest of us.

>>1200273

I'm talking about the things like picrelated, they fit snug into the prop. They used to be a lot more common, before most stuff standardized on 5mm shafts.

>>1200284
i thought those things are inserted into the propeller though? im talking about the adapter that secures the propeller to the shaft vertically so the propeller cant move up or down. i dont even have one of those for a 3.5mm shaft nor can i find one online.

>>1200286
>im talking about the adapter that secures the propeller to the shaft vertically

Wait, are these shafts not threaded or something? As in, you're not just putting the prop on then tightening a nut own?

>>1200288
no they are not threaded.

>>1199706
KV is KV. A larger motor (regardless of whether it's diameter or height) will usually have lower KV for the same number of turns and winding pattern, but it's still possible to find plenty of 1806s wound to an appropriate KV for the prop size I'm considering (2000-3000 KV for 4-5" props).

I'm trying to figure out why my X-maxx is so loud.

When the motor turns it sounds so metallic and surprisingly loud.
Nothing is broken.

Any ideas?

Is there any way to build a long flying drone? All these shitty race drones fly like only around 9 minutes. I've ready that only the DJI drones and other expensive ones can fly a long time. Is it possible to build atoms 20 minutes of flight quad and what would be the price?

>>1200785
I don't know what sort of racing drone you're seeing that flies for 9 minutes, the norm is 4-5 minutes.

It's relatively easy to build a quad that will fly for 20 minutes though. It's not like DJI have access to super secret battery tech that nobody else does. You just need to build appropriately - you're not going to get a racing drone that flies for 20 minutes, same as you won't get a drag car that goes 500 miles on a tank.

>>1200774
That's not how LiPo gassing works. Once it's puffed, it's puffed, you can't reverse the process.

>>1200826
Nah man, stick a hole in it to get rid of the puffing and you're good.

>>1200844
I mean, that's a rather... permanent solution ;)

>>1200844
that will cause an explosion

>>1200846
>>1200850
It starts burning because it gets contact with the oxygen in the air.

So you have to be quick to empty your lungs, and suck the gasses out.
Then simply tape the hole shut after.

>>1200851
Just do it underwater in the sink.

>>1200853
under liquid yes - but don't make it water. Water has oxygen.

>>1200826
Just try it. I didn't believe it at first either. It works (usually).

I've come to the conclusion that heat is the number one cause of puffing, too. Whether from over-discharging, over-charging or environmental, it all comes down to heat. Make sure you store your lipos in a cool place.

>>1200822
>you're not going to get a racing drone that flies for 20 minutes
Probably I explained bad. I dont want a racing drone I just want any drone that can fly around 20 minutes for as cheap as possible. I just want to slowly drift in the air..

>>1201250
low kv motors are more efficient since they can drive larger propellers. larger propellers are inherently more efficient. the bigger your props the longer your flight times.

Why would you not want a wide angle for shots mounted on a car?

I've even ordered a few lenses that's even wider than the one installed.

>>1201250
Bigger drone with as light of a frame as possible. Low KV motors with big props, and as big of a battery capacity as you can fit while keeping the thing flyable. It wont be a performer, but it will fly for a long time.

I use electrical tape to hold things as well, the helping hands aren't always better. Just remember to put another layer of heatshrink over the clips so they don't dig into cables as badly.

my BIG octocopter drone with a wookong needs 12 clicks of trim to take off without tumbling onto its side. I'm not sure if this is due to weight imbalance, IMU calibration, or motor calibration but you can't calibrate the IMU of a wookong so potentially I may always need to fly with this amount of trim and it could remain truly unfixable. Could this cause any troubles for me?

>>1203282
Most people agree that you should never trim a multirotor, as it means that there is an underlying problem (most likely the accelerometer calibration if you are flying in autolevel) that should be fixed properly rather than covered up by trim.

>Could this cause any troubles for me?

If you switch from autolevel to rate mode, it will be a big issue. The trim that you dial in to 'fix' your octo in autolevel will represent a certain angle. But when you switch into rate mode, that same trim will instead represent a constant rotation speed & the copter will flip.

>>1203285
okay, i'll keep that in mind. i wonder if GPS actuated movements such as return to home would also be problematic since the transmitter is no longer in the picture.

>>1203287
I imagine that the return to home functionality would work right up until the point where it actually lands, at which point it might have problems landing cleanly without falling over.

>>1203289
what if I use software trim? It says here:

>Can I use radio sub-trim?
Yes, during test flight you can use radio sub-trim or trim to adjust for leveling flight. We do recommend you to use software trim afterward and re-set all radio trims to zero value.

http://www.dji.com/es/wookong-h/faq_v1-doc

>>1203291
That would seem like the more sensible approach, if you really can't calibrate the IMUs.

how many kv motor should you typically use on a shrieker?

>>1203693
one million

>>1203693
I'd do 13XX or 14XX motors for a 3" build, 3000-4000 KV range.

>>1203295
actually i just discovered that the flight controller thinks the sticks are in their neutral position when I have the trim offset added and it thinks they arent in a neutral position when there's no trim. so it's not the IMU or motor calibration after all. For some reason my 9XR transmitter is sending a slightly wrong signal for its neutral position and i need to correct for it using trim.

which brands are owned by hobbyking?

>>1203798
turnigy, durafly, avios

>>1203800
quanum? why do they have a monopoly?

>>1203802
yes, quanum too. They don't have a monopoly.

>>1203785
I'm not familiar with the 9XR, but on OpenTX radios like the Taranis you can tweak the end points & the centre point of each channel (so you can have exactly 1000-1500-2000 for example). Maybe your radio has a similar function?

Just received my Tyrant 180 kit, will be using 2204 2300KV motors on 4x5 props, will decide if I stay on 2 blade or go with the 3 blade setup.
20A Oneshot ESCs, Kakute F3 board and Immersion 600mW VTX. Aomway clover antenna. Runcam Eagle 16:9 camera.
Looking forward for a nice weekend of building and maybe maiden. I will literally have to re-learn to fly with this thing, will be starting with angle mode crutch and dipping into right mode. I expect it to be fun :D

>>1205356
2300KV is a bit slow for a 4" prop, you probably want to get 2600/2700 if you haven't already bought the 2300.

>>1205360
I will mostly use 4s. 3s for the training, but I calculated slightly over 1kg of thrust on the weakest setup, 2 blade with 3s.
The motors are 2204, not 18 size so will have much more torque to turn the bullnose props.

Could you guys recommend me a quad to build or buy ready from the box that can carry a go pro and it moves slow and stable. I only have a fpv racer atm and it moves way too fast even at the lowest speeds to get a slow and steady clip recorded. Thank you so much. Preferably around 150-200 dollars.

>>1205336
Looks great. How much did that one cost? Built the 99dollar racer from UAVfuture today. Looking forward flying it once the battery arrives.

>>1205375
DJI Phantom 3

>>1205381
Appreciate the reply buddy but that's a bit out of my price range. Id say 200 dollars is my max. It can be diy so if you have some already built sets the order up id be very happy.

>>1205370
1kg thrust from a 4" twin blade on a 2300kV motor on 3S is nonesense. Run your calculations again.

>>1205379
About £160 for that one. Apart from the Runcam & the FrSky receiver it's a cheapo build, but those two components alone are £50.

>>1205375
>>1205387
Sounds like you want something with a gimbal, which you aren't going to get for $200. A Phantom 3 or a Spark are really the entry point for that sort of thing.

>>1205389
4'' twin blade 2300KV on 3s is around 270g.
4x(270g-ish) is around 1kg with the four motors
3 blade on 4s is around 500g per motor.
4050 bull nose props.

>>1205389
3d printed go pro mount will be good enough. I just need a quad to have good movement control on low speeds

>>1205396
>4'' twin blade 2300KV on 3s is around 270g.
>4x(270g-ish) is around 1kg with the four motors

>>1205397
In which case it's more about your skill & the rates/tuning of the quad. Even a mad powerful racer with 8:1 power to weight will make a smooth/stable camera platform if you tame the rates & maybe use a barometer for altitude hold.

>>1205410
I guess your right. It just feels that the racer goes from zero to light speed in such small rates from the throttle stick. Something like walking speed is what im looking for.

Well it's not hard to change the range on the throttle or to put expo on it, etc.? You could even set it up so that you can switch between 'race' settings & 'slow' settings via a switch on your radio.

So that other quad actually felt too light/floaty with these new twinblades, but my heavier 5" suited them much better - effortlessly smooth.

What is the best way to harness the power of energy dense liions? i can carry a huge amount of weight, the only issue is that i can't fly for too long with my current 8000mah 6s lipos.

>>1206000
Efficiency. You have to find an efficient combination of motor, props aerodinamics and AUW.

It was dry enough to go out for a test drive.

Managed to make a good enough mount for the gimbal this time.

Think I will have to extend the mount a bit to accommodate for postprocess stabilization.

This is super cool & I'm really impressed with how that gimbal is performing.

I flew my original Yi on a miniquad for the first time today & 60fps makes such a difference! I was using a 30fps GoPro 3 before because I didn't want to break the Yi as it was my best HD cam, but now I have the Yi 4k for that purpose & I put a chip in the GoPro lens.

>>1206203
Yeah I'm really impressed too, opens up a whole new world for videomaking in general for me.

I wanted to try the gimbal and yi for a drone, but I think just the yi mounted like yours will do the trick. Looks just what I want to do. Great fun!

You got a separate fpv camera though right?

Not using my smaller rc car, thinking of selling/trading it for a used drone.

>>1206223
Yup, it handles it fine & it's a heavy build compared to what most people fly these days.

Is there a sticky or something for starting out with drones? Don't know the more proper term.

>>1206022
i already am efficient. i have eight 15 inch carbon fibre propellers powered by eight 230kv motors.

>>1206208
why do you need a separate fpv cam?

>>1206395
If your flight time is low it mens your motors don't work efficiently or it has to spin the props too hard to hover. I've been through the same when I built my first quad from scratch. Have you tried a tad smaller or lower pitch props?

>>1206439
current draw per motor would be lowish it's just that I have eight of them so in total its quite a large amount and I'm carrying a heavy load. Perhaps the best thing to do would be to have 6 18650 li-ions in series connected to each ESC. meaning 6*8=48 18650 li-ions

>>1206402
HD cams have too much latency & not enough dynamic range for freestyle/racing. They're okay for slower flying styles, but not racing through gates or doing acro. More recent HD cams are better than older ones in these regards, but they're still nothing compared to a dedicated HS1177.

>>1206443
Are you using octo or X8 configuration? On X8 you will need higher pitch on the lower blades or the higher velocity air becomes turbulent when hittung the bottom seemingly flatter blades.
Remember you are still flying with wings so RE number and turbulency is still a big factor in efficiency

>>1206463
Runcam Eagle 2 with WDR or the first Owl are the new standard. The HS1177 is old and deprecated.

>>1206469
The overwhelming majority of the people I fly with & see online are running Swift or Swift 2.

There are a couple of approaches to waterproofing race quads, some people use conformal coating but I prefer PlastiDip (because it peels off clean). I don't fly in rain, but I paint over most joints just for peace of mind & a semblance of more mechanical strength.

Can anyone point me towards dji phantom diy kits or something alike?

>>1206714
Quanum Venture FPV deluxe kit or Nova FPV kit

>>1206714
You're not going to DIY anything close to the features/performance/price of a Phantom, just FYI.

>>1206982
A Pixhawk or an F3,4 or 7 FC surpasses the Phantom in every aspect. The old 8-bit APM beat the Phantom and NAZA.
Any DIY wooden frame quad with a 3-axis gimbal will perform the same or better. Mostly better, the NAZA system has numerous known issues you can't tweak out.

>>1206984
You can't even buy a Pixhawk, a 3-axis gimbal, a radio & a HD video downlink for the price of a Phantom 3.

can anyone point out any good lipos to buy

>>1206992
That is your problem. I built a quad capable of waypoints with 3d gimbal for 1/3rd of the price of a used P3. It was much more stable and had a more fluid motion than a clubmates P3.
There are plenty of pixhawk compatible boards not to mention the F3,4 and 7 boards. Just look it all up, kid.

>>1207012
>I built a quad capable of waypoints with 3d gimbal for 1/3rd of the price of a used P3.

An official DJI refurb P3 is $420, cheaper if you buy on craigslist. Care to post a parts list and some sample video from your $140 build?

Considering the cheapest, crappiest 3-axis gimbal on banggood is $66 and a Yi is $71 on gearbest (and isn't as good as the Phantom 3 camera) I think you're full of shit.

why do you guys like Pixhawk more than the others such as SPRACING?

>>1207017
Pixhawk & SPRacingF3 aren't really comparable. Pixhawk is a FC primarily intended for semi-autonomous, GPS controlled platforms & is usually seen on larger aerial photography rigs with more accessories, payloads, etc. SPRacingF3 is a FC designed for miniquads - non GPS controlled, racing/freestyle builds.

Picrelated, my Pixhawk setup at the top & one of my miniquads at the bottom with something similar to a SPRacingF3 in it.

>>1207022
oh so that's why my spracing f3 with gps runs like crap in gps mode

>>1207024
I've seen people getting decent enough GPS performance on racing FCs with barometers using iNav, but it's never going to compete with a platform specifically designed for GPS/autonomous control.

So now you have to take the covers off to lube the bearings?

what effect does pole vibration have on the accelerometer? e.g. hold a low pole count big motor in your hands and give the shaft a spin then feel the vibrations in your hand as the motor moves between each pole coil.

>>1207022
Any F3,4 and 7 board is capable of semi and full autonomous GPS flight, you just connect a GPS and compass by one of the UART channels.

Sure, but iNav/dronin are a long way from ardupilot/px4 in terms of features & functionality, plus your regular F3/4/7 racing board doesn't have the same flexibility as a pixhawk in terms of servo outputs, number of accessible UARTs etc.

>>1207468
Yes, but the processing power is much more in an F7 board. I see a new pixhawk 2 board based on an F7 or better ARM processor for better stability control.

>>1207489
.... this doesn't change the fact that racing FCs with iNav/dronin are a compromise compared to arducpilot/px4 on a pixhawk (or even an APM)?

>>1207493
APM is equivalent to a Naza V2 FC, so an iNav kit is the better option.

So I just got my skyrc b6 mini from the mail and there's no dc power cable for the device itself?

>>1207507
Except it's really not. On the hardware side, the APM has more inputs & more outputs than a racing FC - good luck trying to fly an octo on your racing FC with it's 6 motor outputs. And on the software side, even the old version of arducopter that runs on the APM is massively better than even the latest release of iNav - I mean come on, iNav doesn't even have MAVLink.

I want to get into drone flying, the goal being fpv race drone acro mode.

Are there some go to "toy" fpv drones that can get you started for a cheap price?

>>1207526
Inductrix or E010 are nice. You can start out LoS and strap a Cam/VTX on it if you want to play around with FPV. They handle fairly different from brushless quads, but you should still be able to figure out if you'll enjoy it.

The E010 & the Inductrix are great fun, but the E010 can't fly in acro/rate mode so it's nothing like flying a 'proper' race quad & the Inductrix is expensive.

Thanks for the suggestions!

That Eachine 90mm seems real neat. I think that's the main contender right now.

Anyway, I'm always keeping an eye out for used rc.

Currently an Emax 250 drone complete with motors, camera+transmitter, dji naza v2, and a radiolink at10 II transmitter.

All for 200usd.

Considering I need a transmitter, new one being around 100usd.. This ought to be a good deal for me as a beginner?

Good or bad idea to get this one and learn with one of the smaller drones I was suggested?

>>1207987
Not a good deal.

The quad will be obsolete (this is a market that moves very fast) & you can buy a brand new quad with all up-to-date components for $140 (search Eachine Wizard). Also I have no idea why there is a Naza on a 250 racer, that's a flight controller intended for GPS camera rigs & you'd need to replace it if you wanted to actually fly it FPV.

The transmitter isn't a popular model/brand & isn't compatible with any popular protocols afaik (eg it won't bind to any of the Eachine micro quads like those previously recommended). You'd be much better off spending $100 on a Taranis QX7 which would then do you for your entire time with the hobby.

>>1207993
Shieeee, I got a lot to learn with compatibility.


I suppose I don't mind spending the cash on a good transmitter that I'll get full use of a larger drone later on.

>>1207997
Yup, it seems like a big investment at the beginning when it literally costs as much (if not more!) than your first quad, but you will literally use it for every other quad/plane/boat/whateverthefuck you buy/build, whether it's a $15 micro toy quad or a $1500 octocopter that can lift a baby. Don't actually lift a baby.

>>1208047
Don't need to do anything special for a first charge. Just always stick to the golden rule of charging at 1C & only parallel charging packs that are within 0.3v overall voltage.

anyone know a good guide on building your first RC plane?

Just came back from flying my virgin racer and christ that thing has more power than i expected. Pushed the throttle a tad too much and it rocketed 40 feet up. Should I tone done the throttle and such from the radio or from betaflight to make it more noob friendly?

I'm looking to build something like >>1201540 but from scratch. I have the electronics working, but could I get some advice, or even diagrams for shaping the aerofoil?

did you guys know that 10C means you aren't allowed to finishing discharging your battery before 6 minutes is over otherwise you risk damaging the battery?

I was looking at these goggles https://hobbyking.com/en_us/cyclops-1.html


thanks in advance

>>1208658
You're better off buying things separate. You can sneak some of it in without paying taxes, for one; for two, you should pick a decent transmitter because you'll be using it for all your RC stuff in the future. Refer to >>1207922 although there's plenty of decent sub-100 transmitters around.

>>1208663
is there something like the i6s that has physical trim controls? or is it not a big deal

>>1208676
Yeah, plenty of them have it, just look around and if you find something you like, post it here, people will tell you if it's stupidly shit. I have a Radiolink AT9, that one has the physical trim.

>>1208676
Look up Frsky Q X7, it is the hottest currently, cheap and fully configurable, 8 channels default, 16 with extended receiver and 32 channels if the transmitter module is extended.

>>1208691
neat.

Also, why don't RC planes use 18650 batteries? Why the pillow shaped cells?

How should I go on fixing my throttle resolution. My max throttle end point is about 80% but quad wont arm if i knock up the minimum from the radio. Can i adjusy the throttle mid point from betaflight somehow?

>>1208737
Because it's not space efficient to stuff round cells in your plane, and because they're Li-Ion batteries that work at 1-2C discharge, whereas most planes draw at least 4-5C and might peak at 20-30C, that would ruin Li-Ion, hence Li-Po.

>>1208737
Power to weight ratio. The less weight, the more efficient it is, but the less capacity the less time it can operate. There is a sweet spot for all builds (usually 1800 to 2200 mAh) where it operates at the most efficiency for the most time.
Solid casings mean more dead weight.

It's the new dshot version of the Radiance from Furious FPV & I'm pretty sure it's the board that's faulty. Any ESC that I connect to the ESC1 pad doesn't work & I've tried half a dozen. That same half a dozen ESCs all work on the ESC2, 3 & 4 pads. I've tried reflashing with various difference versions of betaflight (both the generic pikoblx target & Furious' own Radiance target), I've tried different ESC protocols, I've tried disconnecting everything except power & one ESC to remove any possible interference from other components. And I'm pretty certain I didn't blow any traces with my soldering, as these pads are super easy to solder quickly & at low heat.

Armin wing from Experimental Airlines or alternatively get plans for the FT Spear or Mini Arrow, but the Flite Test wings aren't rounded (they still fly well though).

>>1209157
what kind of advice are you looking for, have you built with foamboard before? Plan it out before hand, if you think you'll make more than one then make a template out of posterboard that you can trace onto the foam. Ed's power pods are easy, but they don't have a clean look. A lot of flying wings have the motor mount at the back, above the airfoil and mount the components in the airfoil or in a center pod between the wings like the Spear or Mini Arrow. However, some things like the battery may stick through unless you have a really fat airfoil.

Here's my wing (it's actually 36"), it flies well with a little eMax 2204 2300kv motor and 5x3 prop and 1300mah 3S. The box to the right is a 20x30" piece of foamboard with the dimensions for the wing. The center pod is just a 4x16" rectangle that gets glued to the bottom of the wings, folded over, cut to length and glued down. Then cut a hole for the battery in the center, and holes for the servos and receiver on the wings. The motor mount is one of the FT plywood mounts.

>>1209185
don't confuse FlySky with FR Sky.

I'm not finding any information on how to, or if, make my x-maxx shut itself down if it loses signal.

Is that only possible with a third party ESC?

Because they have actual engineers designing their stuff. It's a lighter chassi, and it likely has motors with a more efficient performance:power ratio.

>>1209751
>Have you even opened up eCalc yet?
yes. It reckoned I would get 20 minutes. Perhaps I set my lipo voltage warning too high. I set it to 3.8V for when under load.

>>1210012
3.8V would be a little conservative even for a racing quad, where the batteries are subject to massive spikes. For a big slow AP rig where battery load is more steady/predictable, you can safely set a lower warning. On my 650 I have my warning at 21.4V for a 6S (3.56666V per cell) & they generally bounce back to 3.6V after landing.

Flysky is a cheap brand with cheap build and non existent quality control

Fr Sky is a budget brand with good build and good quality control and has set the current standard in multicopter and general RC transmitters.
Basically Flysky is shit and Fr Sky is top of the line.

>>1210115
Turns out that it has it on by default.

Now that I think of it, all the runaway cars I have seen were with third party setups. So I guess they simply forgot to turn it on.

Very difficult information to find.

>>1209907
The power pod isn't terrible, but it's not necessary if you can put everything in the wing. Also, Ed tends to put his Lipo way out front and I like to give it some protection from a crash. Look at the Synapse compared to pretty much every other flying wing out there.

https://www.youtube.com/watch?v=AAFfI1g9Uco

>>1210124
There are two kinds of failsafe. One (the default option) is leaving the positions on the last known setting and the second is going to a set position you set yourself.
If you didn't specifically set it yourself it means it will plow on when losing signal.

>>1210128
I found an online manual which says it requires no user programming. Default is zero throttle and last known steering servo angle.

Get the Tyrant S, it trumps the wizard for $20 more. Get the new Kakute AIO F4 board too for an upgrade.

Flew gates for the first time today :) Got a little sunburned as well :(

>>1210303
How much practice did you have before you switched from angle to manual flight?
What kind of practice would you recommend for a beginner?

>>1210126
will carving out a section in the wing for a lipo reduce the strength by a lot?
>>1210116
is the $100 Fr Sky necessary or will a cheap 6ch banggood one be fine in terms of my first serious 6CH TX

>>1210372
I still fly exclusively angle for LoS, but for FPV I started in manual from the beginning - angle mode really is a hindrance for flying FPV. But I learned how to fly manual using a simulator (specifically LiftOff, but there are others available too), because it meant that I could spend 20 minutes taking off, immediately losing control & crashing then resetting, rather than having to spend weeks with a real quad getting 10 seconds in the air then having to walk home & spend hours fixing.

>>1210506
Think about it, the quads will change but the TX stays with you. Do you want to get stuck with a cheap shit or do you want to start with a decent one from the get go? I've been through this and I strongly recommend getting the FrSky. It will save you so much frustration and negative experience, it certainly worth its very low price. Just look at a Spektrum DX 9, Hitec Aurora 9X or a Futaba Fasst 8 channel TX, look at their price with their limitations and compare it to the FrSky that has no such limitations.
I'm on an Aurora 9 and I would change to FrSky in no time if I wasn't so heavily invested into the Hitec system.

>>1210541
what are the limitations of a Futaba Fasst 8 channel TX?

>>1210506
>will carving out a section in the wing for a lipo reduce the strength by a lot?
No, this is very common on solid foam wings and I've done it on my foamboard wing with no effect.

>is the $100 Fr Sky necessary
listen to the advice from this anon >>1210541 and elsewhere in the thread. Buy a decent programmable transmitter from the start. I bought a Spektrum Dx5e which was still $90 and since it wasn't programmable, it had to be set up for each new model, losing my trim settings for the last one. Next I bought a Turnigy 9x and eventually put a FrSky module in it. This was still $70 (with the Turnigy module) plus the additional module, plus all the hassle of putting the fucking backlight in and the programming board for OpenRx.

>>1210566
Mostly the settings, but this applies most big brands. It originates from the early programmable radios, highly simplified mathematical functions for setting various wing configurations. Easy to set planes, scales and competition gliders but not flexible for multicopters and other advanced on-board electronics. Spektrum and Hitec developed this further, but Hitec still relies too much on the "Futaba heritage". It is a flexible system but I still get frustrated about stuff like half travel for flaps unless I do some crazy mathematical setting for the spring switch and that I can't rename the "Normal" flight condition. My Naza quad has no "Atti", only Normal, Manual, GPS and Failsafe. And the programmable mix is limited to something connected with something, can't do a simple setting for a channel with multiple levels mixed to switches. I have to use a nothing mixed to aux channel and I can tell it is on the edge of the programming limits because this kind of mixing puts artifacts on the setting screen.
Also there are no small CPPM or Sbus out receivers, I have to use the FrSky Delta8 for a CPPM out.
Other than this, for regular fixed wing models it is a crazy good system, only if Hitec would do an upgrade similar to OpenTX. Which it will never do and the other big brands as well because they spent so much money coming up with these limited systems so they can sell more overpriced multiple level TX.
FrSky in comparison is a users brand, listens to user comments and develops their products accordingly. It is night and day compared to the big brands. I suspect the big brands will have a big recession soon only because of FrSky and OpenTX.

my Hubsan H107L has two solder points on the board which I assume are for the camera power for the camera version; they seem to use the same boards for both versions. Could I just solder my Wolfwhoop WT05 onto it? it needs 3.3V-5.5V....

>>1210568
So I guess I have to get a Frsky Q X7 if I want to progress in the long term. BUT, what if for the next ~2 years I only want to fly my diy foamboard wings. Then can I buy a chink Tx/Rx combo? I just dont fly more than one a month right now and I am still hesitant.

is it wise to start off with low kv motors and then gradually increase kv as your piloting skills improve?

>>1211065
if you're really not sure, test the pads with a multimeter, but they probably are using the same board.

>>1211120
just do what you want.

>>1211140
No, that's not how kv works. If you are want to limit your speed/power when starting out, do this in betaflight by setting low rates & maybe reducing your throttle range.

Thanks for this, Anon. Would you happen to know how to carve an airfoil out of solid foam without a hot wire cutter, or will I just have to make one?

>>1211242
If you're talking about a miniquad, then it's not a bad idea to buy a 4S capable setup but start with 3S batteries.

Looks overly complicated design, too much dead weight without much improvement in structural strength.
I would fly something like pic related. Actually building it as I type.

>>1211284
how do you mount a camera on that?

>>1211364
Maybe where it literally says 'camera mount'?

>>1211392
>Maybe where it literally says 'camera mount'?

thanks. maybe tone down the rudeness a bit.

>>1211284
I've run into some problems.
The PDB has a 5V BEC and the FC, Kakute F3, has a 5V BEC also that is used to power the FC. How should I wire up the power for the RX?
Should I connect it to the low power 5V out on the FC and leave the PDB BEC for whatever or can I use the PDB BEC while the FC uses its own BEC? Won't the two BECs open each other out and fry everything?

>>1211407
Your flight controller is intended to provide 5V to your receiver, so do that. Use the PDB 5V for LEDs if you have them.

>>1211418
Thanks
The PDB has 12 LEDs built in already.

>>1211243
No, hot wire is the best way to cut foam. It's also stupid cheap to make a hot wire bow. I don't understand how some of these companies (Team Legit) charge so much for handheld hot wire cut wings. However, if you find the cost of the bow to be a problem, i would look at some kit planes. You can get a Z-84 for $31.

>>1211820
>I don't understand how some of these companies (Team Legit) charge so much for handheld hot wire cut wings.

The same way that Lumenier charge $100 for a QAV-X while Realacc charge $25 for their clone? The original R&D isn't free.

>>1211825
>The original R&D isn't free

no shit, but how much margin do you need to make on a kit like that? The chink PNP models that are injection molded are cheaper than a pair of foam wings that can be cut in a garage with a $20 hot wire bow and some templates. They're using pre-existing airfoil designs, what's their R&D cost per model? Maybe $500? I could say the same thing for the frames to an extent. They're all mostly the same.

>>1211829
Well, nobody is forcing you to buy the 'overpriced' ones.

Ghetto-rigged a tripod spine to the car for longer reach to counter the crop of EIS/stabilization.

I haven't figured out a way to counter the gimbal pointing down from the torque of the car.

Going to the countryside for a week so I'll have plenty of time and place to test my stuff in a proper environment.

Favorite setting is the 1080p ultra 90fps. It makes use of the entire sensor, hence a wide angle view.
Also enables for some cropping from postprocess stabilization.

Thinking of making some platform held by 4 shocks in each corner to mitigate the slamming knocking off the gimbal.

>>1211929
This is by far my favourite angle so far.

>>1211928
>I haven't figured out a way to counter the gimbal pointing down from the torque of the car.

I found something similar when using my handheld Zhiyun gimbal on a plane during take off. Presumably the g-force screws with the IMU.

>>1211928
what gimbal and how much did it cost?

>>1212002
It's that thing that messes up it's track of the horizon I think.
I've noticed that my gimbal very slowly goes back to the position I set it at when I've stopped the car.

And yes, the very wide angle is really neat.
I'm going to try a top view, should show the wheel/suspension action a bit more.

>>1212014
The gimbal is a zhiyun rider M, I got mine for 340usd. There's much cheaper ones out there, but this was the only wearable gimbal I could find in my country, and in stock.

The webm you quoted has EIS too. I've noticed they kind of counter each other sometimes though, the gimbal and EIS.

At the risk of being a buyfag, if I could spend $500 or so and get two gas powered cars with FPV that turns the camera when I turn my head I'd be ordering them right now.

Man oh man toys are really getting nice.

>>1212029
I think it would take $500 just for the head tracking goggles.

Let's say I don't need to go fast; I just need to carry a gimbaled gopro and have a good duration flight. What would be a good quadcopter kit for that use case?

>>1212036
Mavic.

>>1212037
It can't be a DJI product though. I'm helping a dude put together a drone and he says no to anything DJI

>>1212042
>>1212036
You're not going to DIY anything better than a DJI for this use case, even if you spend double the money.

>>1212047
really? what's the limiting factor for DIYing it? Like what ability would it not have

>>1212036
Any home made 380-450 H frame, Tarot ~950KV motors, 9x6 Apc thin electro or equivalent props and a 2D gimbal in front like on a Mavic, yaw can be used with the quad instead of a bottom mounted 3D gimbal and huge retract legs.
GoPro or RunCam 2/3, maybe the Runcam Split, 2200 3s or 4s batteries.
Pixhawk compatible FC and 30A Blheli opto ESCs, separate BEC.

Look up FT versacopter and wooden H-copter plans.

>>1212068
For just a gopro gimbal rig, diy can be done. But pretty much all of the DIY hardware/software that currently exists is massively outperformed by even an old-model DJI. For what you'd be spending in parts to build a mostly-reliable camera quad, a used DJI will do the same stuff. Even a phantom 1 with standlone gimbal (dead cheap on the used market) will probably outperform a custom rig in reliability and ease of use.

if you don't need any of the software functions that DJI offers, then you can /diy/ one for much cheaper than a mavic or phantom, even DJI sells kits.

>>1212076
2.4Ghz sorts itself out, especially FrSky.

>>1212080
What about FPV though? Even my small local meetup has had issues with people powering up on same/similar channels.

>>1212076
2.4ghz control works fine, usually. Some of the OrangeRX stuff locks out during the combat sessions and whatnot.
Video signals are managed by volunteers at the FPV flightlines, but I'd still not want to fly FPV there. There's too high a chance of someone powering on your frequency (by accident or similar) while you're flying.

>>1212084
Left/Right circular polarization, and not having more than 8 transmitting on each polarization. Directional antennas could help to some degree as well.

>>1212068
The software & the digital video downlink are the big ones & they add a huge amount of performance & functionality when it comes to actually recording video/photo. For the price of a second hand Phantom you would struggle to even buy a comparable digital video link, let alone all the rest of the parts to build a quad & even then you would have no control over your GoPro except pressing record before you take off & hoping for the best.

What's a good bix3 alternative? Something a bit more user-serviceable

>>1212213
Honestly, FT explorer. Scratchbuilt airframe is probably the most "user serviceable" you can get.
Other than that, there's probably 10s of other "sky surfer clones" to choose from.

>>1212218
seems interesting. I'm also looking into the XUAV Mini Talon, it seems pretty good for a noob too

>>1212249
>XUAV Mini Talon
That design really sketches me out, Id imagine getting that thing to balance would be a pain. They aren't really meant for beginners, too fast.
Honestly, if this is your first plane, a bixler (or FT Explorer, if youd prefer that rout) would be a great first airplane to dip your toes in with. Trying to go "UAV" rout before learning to fly just a basic rc plane wouldn't go too well.

>>1212268
well I've done plenty of flying with tiny LOS quads. Just want to do some fixed wing stuff. The Skipper XL also seems neat, but yeah I'll probably go with the bixler/explorer. Or maybe the super cub s? It has good reviews

>>1211820
It's not the cost, I just can't be assed to build one, but I guess I'm doing that now. Thanks anyway.

>>1212273
If you like the float plane idea, I know they're discontinued now but if you can find a Multiplex Shark, they made a float set for them. I've got one and its an easy flying plane, I'd recommend it to a beginner, I haven't tried the floats yet but it shouldn't be any worse than any other seaplane.

>>1212273
>>1212290
The sport cub S is certainly easy to fly but it's kinda pointless for what you want. It's so small, you'd want to get something bigger anyways, and a bixler type will do much better in that regards.

So if, hypothetically, I was an idiot and bought a brushed DC motor for my RC plane, what could I do about a speed controller for it? It seems that they're only available for AC brushless motors.

>>1212298
The BEST solution is to go and buy a brushless motor, they're leaps and bounds better.

But if you're dead set on using that brushed motor for something, there' still are a few speed controls out there for them.

HELP! Is is possible to ruin your flight controller for good with zadig? When I plug the flight controller in it just shows "unknown device" and I cant even install the drivers with zadig. The boot loader works with dfu and I can flash new firmware but still when I plug it in norma I get "unknown device". Im desperate. Iv been fighting with this for many hours.

>>1212371
Nvm the usb plug was loose. No way I can solder this back in. Goddamn cheap electronics

So I bought the QX105 and QX95 since it was on sale. I apparently successfully binded the QX105 to the FS-i6 since the green light is glowing steady when it's on, and blinks when it's off. However, there's no response from the transmitter in BetaFlight at all. I'm having a hell of a fucking time trying to bind the QX95 too, it just won't go. I updated both their firmwares now and it's still the same shit.

Is it the transmitter? I've been using it in FPV PE and Liftoff just fine. Or is it the board on the quads?

>>1212400
Y'know what's great about cheap electronics? They're cheap.

hmm, the RMRC Nano Skyhunter is EPP foam, but the Eachine banggood one is EPO (and is cheaper).

Is there a reason to go for the RMRC one?

Did I manage to discharge it with use just enough or is it broken..?

You probably used it to just above or just under storage charge. Do you not have a battery checker for the field & a charger that tells you the voltages?

>>1212558
Well not exactly, I either drive till I am satisfied or the ESC tells me the battery voltage is too low.

The traxxas-ID charger doesn't tell the voltage.

This isn't rc related, but I figured you guys would be the authority on mixing electronics and hot glue. The plastic cover for my laptop screen has broken at one of the hinges. Would I just be able to fix it with hot glue, and is there anything I should know to avoid damaging the screen's internals?

>>1213090
Hot glue is safe for electronics (people use it a lot in the RC world to provide rudimentary waterproofing/strain relief/mounting) however it doesn't have the strength to fix any mechanical parts of your laptop hinge. It will be fine to just hold the outer plastics together, but it's not going to bond the metal hinge to anything.

>>1213090
is it an HP envy6 by any chance? Because the exact same thing happened to me and I fixed it using epoxy. epoxy has a lot more bonding strength than hot glue.

>>1213090
I used Epoxy on my moms laptop, still holds together after so many years.
I recommend Araldite 5min. let it sit undisturbed for the rest of the day so it can set properly.
