The engine is destoyed, it locked up so i took it into my local hobbyhop and he said that the cylander has 3 major gouges and the piston is deformed. ive been thinking about an engine the hobbyshop guy told me about he said its a .26 its an os dimamite for its $130. Do you guys think that a hobby shop would let me trade the chassis in for a decent electric car, if so what are some good ones?
