These rigs have a terrible center of gravity. Every since i got mine its been terribly nose heavy. Added arrma 4s tires and a bigger can motor just to get it to back flip. Now that i got that settled. The dang thing will land on all 4 tires, and the a** end will bunny hop back up and it will end up on its lid. Ive played with suspension settings to no help. Even if runing across the yard, if you hit a bump it will cause it to rear up and flip over. Very very annoying. Any one else have this issue?
