I prefer to fly the pattern style; but with my switch to the 40 and 90 Funtana's and 70 Katana, the patterns have been collecting dust. The latest pattern style plane I've bought was the Quest 90 from Ultra RC. It tracks so straight - up, down or knife edge. Then I saw Ultra's flight video on their site and the Quest was doing 3D even with the small ailerons. I'm not sure how the U-Can-Do series would work.
