interesting project but.. I'm not sure about traction on slippery surface... imho FWD is good for low-power motors (as in video you've posted, 1/10th buggy with 400-size silver can).. But with stronger motor it will have lot of wheel spin and no acceleration because of weight transfer towards to rear-end of car.. That's why I'm trying opposite project in RC rallying (there're lot of FWDs - based on Tamiyas FF-s or M-s - and no RWDs because there is no base onroad RWD with IRS), because FWDs has poor acceleration and have problems with jumps and hill climbing.. but RWD handling is much better, closer to 4WDs.. I think that buggy wil be very similar = good for high traction - low power, but not for low traction or high power conditions.
