Need help with RC car refurbishing

You are most likely going to have to fabricate your own parts to fix it.
RC cars arent like real ones where they just keep making replacement parts when the car is out of production

OP here, yeah. I imagined as much. We're 3D printing a couple parts small enough to print and that won't take much physical strain. Other than that it's going to be homemade parts and jerry-rigging the hell out of it.

Take pics and keep us updated

I dont know too much about RC stuff though

First things first, take the engine and the differentials apart, give them a good cleaning and lube. For the diff, use a decently thick grease or oil. For the engine, a 3in1 machine oil should work just fine. Don't use much as nitromethane blends have lube oil in them and any oil you put IN the engine as rust protectant will need to burn off before tuning. Same goes for the carb. Check the seals.

For the front suspension, you'll need to give a pic to give a better idea. If its the shock "tower" you can replace this with metal, carbon fiber, or even a rigid plastic milled out. In fact, you can do the same with most parts that don't get a lot of stress on them. Don't feel you need to replicate the parts, only duplicate the function.

Try and use the pipe if at all possible as these are tuned to give the 2-stroke engine enough back pressure to function. If the manifold is still in place, you just need some high-temp silicone tubing and some zip ties. If you need to replace the manifold, get some 1/4" steel to make the mounting plate (piece that mates to the exhaust port on the engine) then bend some tubing, this can even be aluminum. Then braise/weld the pieces together. Some engines use bolts to hold the manifold on, others use a spring to wrap around the cooling head.

You might search tower hobbies, or ehobbies for parts, especially universal parts. Don't be afraid to make your own parts; they'll be ugly but if they work, they're not stupid.

make a build log OP

Somebody knows their shit.

I'll try to snap some pics on Monday

Sure, I can try. Right now we have the frame and all of the components separated from the baseplate. Working on scrubbing off a shoddy spraypaint job so that we can repaint it and make it look nicer. We have another guy who knows a bit more about engines and shit working on cleaning all that. It's caked with mud and all sorts of junk.

Same guy as before, for metal parts you can use some non-chlorinated brake cleaner; available for pretty cheap at most auto-parts stores and even home-depot type places. Try not to get it on the silicone seals around the engine. Clean the carb well because the old oil has likely gummed up the tiny needle ports.

Another thing about the engine; its either going to have silicone seals, or paper seals around every bolted on part to the crank case. These are super delicate and hard to find. In a pinch, you can make your own seals with gasket material, but its super thin and won't ever be right because that gasket material is meant for large engines and large surface areas.

Look on google for an assembly manual for this model; if you can't find it, video tape one person disassembling and narrating what they're doing so you can take the thing completely apart, clean up every part, assess any repairs, then put it back together.

I'll try and work around my schedule to set up a good checklist for this. You've given me a lot to tell the group on Monday.

>>1111523
Left out a detail that might help. RACO stopped producing these in the early 90s, meaning that this car is at least around 20 years old.

>>1111530
Right, but thats the beauty of 1/5 scale and fabrication: you can still buy engines and fab anything you need to make this car essentially indestructible.

Make a checklist of everything wrong with the car, and I'll help with possible solutions where I can.

>>1111536
Sounds good, thanks a lot.

I heard that some 1/5 and 1/6 cars can be adapted to use use small chainsaw engines.

>>1112634
Thats probably true; if OP is correct and it is a 23cc engine, thats about the same size as a weed whacker engine. A lot of the heavier duty chain saws are a bit bigger at about 30-50cc's.

>>1111536
Also, having a written down, well planed checklist, TO-DO's and possible workarounds might be as much as a help for yourself as for getting better grades/recognition from your teacher.

Damn, this has been a busy week. Sorry fellas. So the rest of my group has taken to just cramming some parts together and hoping it works, and I don't really think they'd be open to the idea of turning back and making it a bit more proper. But hey, fuck it
>Don't feel you need to replicate the parts, only duplicate the function.

If it explodes or some shit I'll let you know. Don't have any pics that would be useful as of now I think. They already had it disassembled by the time I could. I'll try and peek at the thread when I can. Reminder my school has 4Chan blocked so I use a VPN. No posting for me while at school.
