Be vary of the tr15. The idea of a 1/10 scale all wheel drive buggy sounds great. In actuallity this kit falls way short of its concept. Put it on flat land and there isn't much that can stay with it. Jump it and it will break everything. I had great hopes for this kit and in the end after buying evey option part i could get my hands on i let it go for nothing on E-bay. The biggest problem was the suspension for the lack of better words was crap. I tried to solve the problem several ways even using Assoc. shocks from a b3. It helped , but it was useless. I would suggest a RTR GT. Parts areadily available and is supported by the after market industry.LOL.
