I had an ultra stick. It was a great flying airplane, with a huge performance envelope. Barn door elevators and flaps, easy to work in. One major problem though, at a distance without a destinct canopy or color differential top to bottom, it was difficult to tell the attitude of the plane once I started doing some aerobatics. I will never again buy an airplane with see through coating. Different colors top and bottom are a must. Low wing planes offer better aerobatics, but are a little less forgiving to sloppy flying.
