I have had two Aeromasters and have an original Andrews kit in my personal stash of kits waiting to be built. Obviously I think highly of this model. However bear in mind that this model was from a different time(I first saw one in the mid-sixties) when a different style of flying was in vogue and engines were significantly less powerful. IMO the flying then was smoother and with less radial snapping maneuvers. The Aeromaster excelled at this type of flight. I can't say, but would not expect one to fly like today's very light, overpowered Ultimates. It is a classic that was the best for it's time.
