I'd suggest a double decker design rather than a TVP. The Traxxas stuff you are using is more suited for that than TVPs anyways, as revo is almost a double deck design anyways.

Heck even G10 fiberglass would be better than lexan. But really yeah, if you want a "tank", you should go with 7075 or like 3mm CF.

Keep in mind most of the SC 4WD vehicles are around 6lbs, and the 540/550 SC motors are oriented towards 2S usage (ROAR, bleah, stupid.. should have gone 3S for 4WD), so more voltage should allow you to use lower gearing, so should keep the motor cooler.
