how difficult would this be. i know i would probably have to use some metal to reinforce the chassis where the motor mounts on and i could figure out the extra servo and stuff but how hard would it be to find a belt that would work,cause i don't want to try and mount a special gear drive to connect motor and tranny.

it would be cheaper to buy a nitro evader, the plastic chassis will flex with the torque of t he motor and u will keep shredding spur gears etc, belts, not a good thing offroad, especially when there exposed to rocks, dirt etc. Find a cheap roller on ebay, u can get them for under 100 bucks.

Really, if you have to ask then it may be too much custom work. I thouht about converting a B4 once though. If you decide to do it, good luck.

One of the reasons nitro has an alloy chassis is to help absorb the heat form the engine. Acts like a heat sink to help cool.

i'm gonna have an extra 24.7 motor thats about 4-5 yrs old laying around and my electric evader both will just be sitting around thought i'd try it.
