Because the mass of the vehicle would require a very strong diff. That would require a large ball circle (large diameter diff rings) and there is not enough space to do that in the car without making for impossibly high outdrive placement. It would also be very difficult to know if your diffs were too loose over the noise of the nitro engine.
