hey i was jus wondering how i would go about converting my electric powered rc truck to fuel powered .
a simple step by step instructions would be nice thankin u in advance

Step by step for what? You don't even give chassis info. You make it sound easy considering that it's rarely, if ever, done:

Step 1 - take out electric stuff
Step 2 - put in nitro stuff

Your best bet would be to sell your electric truck and put that money toward a glow powered truck. You can convert nitro to electric fairly easily, but it would be almost impossible to convert an electric to nitro because of where the tranny sits and its lack of a mechanical braking system.

sigh never mind
i have no electric knowlegde a lil pc knowledge
im sure i could figure it out i think i gonna see if i build a helicopter in the mean while from jus motors and i dunno wat else ican find

It would not work too well. The nitro gear is alot heavier and generates heat that can melt the plastic and spilled fuel will make the plastic more brittle. Sell it to get a nitro or save money.

go for it! in the last 20 something years i have converted many cars and buggies from electric to nitro, some had aluminium chassis some with plastic and carbon, i never had any trouble with any plastics getting brittle, the first one i ever did was an old 4 wheel drive Hirobo buggy , a bit of work went into the drive train from the clutch to the spur gear, but it used a cam chain from a small motorbike to get the power to the rear diff , the engine i used was an old airplane engine with a homemade heatsink fitted to the head, im building a car now with many spare parts i have aquired, the chassis i am making with a sheet of aluminium, and im using a .39 heli engine , i have bored out a kyosho inferno carb to 10mm and trimmed it on a lathe so it fits the engine, and its now got more revs and powerwith a bit of port work . Im more into boats at this time but when i get bored with one build i go to the next, at the moment i am building an airboat with a .61 engine a 26cc gas deep vee and a .15 deep vee and the .39 car, yes people say im crazy, but it dont stop me having fun

I looked at your post count, don't be discouraged. It took me wks. on this sight to finally be taken serious and get answers. 1. Measure your available space with electronics out. Instead of having your battery,ecs and motor, this is you new available space for notro. Most likely you will have a 2 channel radio so mostly think of going forward no reverse. You are going to need a a nitro motor and transmission these can be bought together or buy matching pairs seperately.You are also going to need battery power to the servos operating steering and throttle. Like another post said you are looking at some expense if you cannot fabricate to your needs. It will taKE SOME SCIENCE AND THOUGHT ON HOW YOU CAN HAVE YOUR TRANSMISSION TURN YOUR WHEELS. Sorry hit caps, anyway the transmission needs to touch your Spur gear and most likely they will not match. Best bet buy a used Nitro and learn the in and out, then design. It seems you are trying to jump in to fast with little knowledge. Walk before you run!

There are several reasons a nitro has an aluminum chassis and one very important reason is to help dissipate the heat from the engine. If you ever ran a nitro vehicle and felt the aluminum chassis you will see how warm or hot it gets. I am not saying not to try if you just want to experiment but many not work as well as you would like.
