It flew great with an MVVS .45 on front. The cowel was about .25 short and the instructions were a little vague about where to locate the rx and battery. But as far as flight is concerned... fast and straight... all you can ask for in a prop jet. As with all prop jet you need to keep speed up while flying. I tried to turn mine while slowing down to practice landing passes, bad idea. It needs speed to fly. Other wise an excellent plane I recomend it without reservation.
