My dad just got off the phone with Hobbico (hes not easily prsuaded like me) and they admitted they did not fix the engine, even though they knew it had been in a crash, and that I had paid for it to be fixed. They must have taken it apart and not put it back correctly since they did admit they had in there notes what was wrong with it....Now i have to send this back to them and they'll take there time fixing it im sure.
