Yah, I've had E-Revos in the past (In the dark ages, when I was still into off-road), and became a pro at adjusting the F1 style suspension, and even modding the chassis, so I know what you are saying about the chassis.

Given it's poor gymkhana abilities, I attribute these to it's motor-above-centerline location, the fact that a one-battery set up unbalances it even further, the almost "oversquare" relation between it's wheel track and wheelbase, and you could try 100,000 wt diff oil in the rear. Heck, you could go even thicker, without giving up dif action in the rear end, and still have both rear tires spinning.
I thought of putting the ESC and receiverINSIDE the right battery bay, a LiPo in the left, and leave nothing but the motor on top, but that still leaves the bulk of weight over the wheels.

Yah, the design was meant for off-road, and that is where it should have stayed. I get a kick out of the guys at the rally thread at the mini/micro forum, and their cockamamie ideas!
