Hi I'm new to rc cars just got out of another hobby i was driving my tmaxx and i it a curb i was going fairly fast anyways after that it stopped working and was leakign fuel.I took it apart and it had a cracked fuel tank and the battery holder for the double a's was cracked anyways i replaced them and the engine comes on but it wont move at all any suggestions? There was nothing else broken as far as i could tell with my eyes but is there something else that could have cause this? Any help would be greatly appreciated.
