Hi Joe...well I have to be honest, I have kinda backed away from your thread. You had the right idea but you are listening to way too many people and most don't have a clue to what there telling you or suggesting you should do! I'll give you this last bit of advice...dont get caught up into most of these guys tales...and for the plane you have here, the 45cc engine is way too big, heavy, and powerful for this planes light airframe! The correct engine, with plenty of power for this plane is the 26cc and NO MORE than a 32! Thats it! Plain and simple this plane and its light airframe will do you wonders with a 26cc engine when propped right!
Thats it for me buddy and good luck!
