1. Use the CIMS
2. If 4 wheel drive have a caster mechanism to pick the 2 front or 2 back wheels up! It is very hard to turn in 4WD.
3.Place your tranny at the back of your robot. Take the output of the trannies to each back wheel. Then take a chain from the back wheel to the front wheel.

Last year we used #35 chain on the output to the back wheels. We then used #25 to connect the front and back wheels. We never had a problem with the #25 chain. If the #25 chain does break then you probably just saved something in your tranny from breaking; you will still even be able to drive around (three wheel drive) YAY!

I have more up my sleeve just can't think of them off hand.
