Yep, lightly cable tie the ESC down if I were you. Not tight at all, just enough to stop it coming off. I've re-taped my nephew's down with sticky servo tape as it came off. It's a fast fun truck but not sure it's competitve for racing at all, I doubt it. But not sure many clubs even race truggy's do they? I might be wrong though. As a basher it's decent but definitely duct tape the inside of the shell up, with the stock bumper being so small the front end in particularly can bend so much in a front end crash it's guaranteed to smash.
