Rustler VXL mid motor conversion
 

I have been meaning to do this for a while, since moving to lipo, the 3s I have is very powerful and not very heavy (I was running 9cell NIMH). This has upset the ballance a bit and turned it into a complete wheelie machine. In order to combat this I have spent a total of 6 hours and an old chassis, I didnt want to butcher my good one, turning the transmission around.

The aluminium gearbox case, like many of them, can have the wishbone/arm pickup points fitted to either side. This is essential to keep the toe in and anti-squat/caster on the rear arms.

had to trim a few places here to get the gearbox to sit flat in the chassis

with the rear of the chassis cut away it was very flexible, this brace screws to the chassis and the back of the gearbox, then the gearbox to the chassis again. The result is actually stiffer than the stock setup.

Rear brace for the shock tower and wheelie bar. The black plastic im using is delrin, a tough nylon.

had to make another piece to attach to the rear brace and then to the bottom of the wheelie bar

nice project how much did it cost for the alloy gearbox. and how much would it cost for you to do one the same as your . love it :thumbsup:

The gearbox was about £30! pretty good I thought.

Depends what lipo your running, I made mine to measure for the rhino 3s 4000mah.

all my battery are 2s lipo demon turnigy 5000mha 30c . i would need to buy some more lipos
