Nice Mutant Maxx.
BTW, for those that do not know, the Mutant Maxx is modeled after a buggy and thus runs with a front, center and rear differential.
As for your issue with it raising one wheel up, I would check to make certain that your chassis is not flexing under the torque from your engine. That would allow for the right front tire to come up. If it is not that, try and stiffen the left rear suspension a bit. Odds are, your truck is squatting to the opposite side under acceleration and allowing the right front wheel to come up. As for the ballooning tire, if your tire is properly glued to the rim, you should be fine. It is natural for the tire to balloon under rotation where they are airborne. If the tire is not glued properly, the ballooning will eventually remove the tire from the rim.
