I have this plane with a 46fx on it. Don't know who built it... flies awesome with the 46fx. i have an 11x4 on it right now and plan on trying a 12x4 soon as i can get one. With the wood 11x4 i can get it right on the deck in a hover at about 3/4 throttle and still pull out vertical. You'll love this plane. It has a very wide flight envelope... really slows down on landings. Good luck with it!
