i converted my ntc3 to an electric rally with some custom bits. worked pretty well all things considered but didnt take long to realize the chassis just cant handle the stresses of offroad life.
the way the shock towers are part of the trans case is even MORE of a problem with it than it was as a nitro touring car, and shereing them off.
however... aluminum chassis is very spacious for all the electric goodies while maintaining quite good left/right weight bias. the shaft drive, just liek the electric tc and df03 is mostly contained, though a spur cover would be nice.
I made one from scratch to use a tc5 dif outdrive set and had a center dif on mine, which worked great but a fluid filled gear dif would be better.
i beat the living piss out of it. most people think rally car, a little dirt, some little jumps and that stuff, i powered it with the same boosted 7.5 system and murdered it on the track lol. worst thing that happened was a turnbuckle would pop off or somthing.
i might come back to that car with some new parts. ie, design it more like a offroad buggy layout and use a mod1 steel spur, though moving the center dif that way would leave very little room for electronics.
all in all, a pretty good chassis to convert. parts are redily available, just need to cover up the gears somehow, or use metal ones. the ntc3 single speed middle shaft might be my route for this in the future, if i can find pinions that will work.
which of course means all the stock center shaft bulkheads are directly compatible, just need a mount for the motor, which id probably steal from a pancar or similar, or tc3/4 motor mount of course.
