i flew mine for the first time today. 2 good flights. the second flight was dead stick and hit sort of hard. The retracts held up great. no folding or bending at all. I put a saito 90four stroke radial on it and it flew scale at best. but this is an under powered motor. any 91 four single should have it screaming. It was a bit touchy in the elevator and seem to have a rudder twitch. But the landings are smooth. It may even float too much. The gell coated fiberglass cowl is week and stress craked while drilling mounting holes. but it is VERY VERY cool in the air.
