I am dabbling in this somewhat... I have a few ryobis in the works, and am thinking of finding a homelite 33cc to put in an ESM P-47... anyone have any guesses on fit & performance?? Some have flown this plane on a CRRC Pro 26cc with ok results... I wonder how the Homelite would compare? I'm not going to give up glow or electric, but I am "pumped" on going gas for a while!! hee hee
