I understand your problem, and sure in a configuration like this there are compromises to both forward traction and the 'ideal' weight balance for cornering and/or jumping.

However, if people manage to make their cars backflip through the air and land on 4 wheels by adjusting their throttle with a car with the weight slightly to the rear, then I think it can too be done with the weight up front, even if it's only 2WD. I managed to make my TRF201 land almost vertically (both nose first and motor first) on the jumps of an average 1/10th scale track. Why wouldn't the car be able to do the same going backwards?

I've seen video footage of BloodClod's FF buggy and Grahoo's (TamiyaClub member) FF buggy, and both seemed to manage the jumps pretty decently (even if the jumps Grahoo's buggy made were pretty small).

And if physics somehow don't at all work in reverse, then I know it's time to get a bit more creative on the design: Perhaps a system that changes the weight balance during acceleration or on command of a switch will be the answer to the problem, a gyroscope, black magic?
