It flew great. It jumped right off the ground and the ryobi was plenty of power to pull around this 15 lbs 11 oz plane. it looped and rolled with no problem. the vertical was somewhat short but still usable for most arobatic manuvers. All in all it was real solid. the ryobi didnt miss a lick and waqs flown several times that day. I think its fair to say im hooked on large gas engines now lol.
