Don't see it as a mistake, but more of an oportunity. I did exactly like you... almost. I had yet to fly my trainer when I ordered my 40 sized Ultimate. I had the same vision that If I have this plane, It will do the same thing the big guys do. Fact is, it does not. It does everything faster though. Rolls are unbelievable. Spins and flopping are just rediculous. It is very difficult to harrier or hang on the prop compaired to it's larger bretheren. You will still enjoy it for what it can do. Keep it in close to you when you first fly it. those two wings mess with your orientation a bit at first. Keep just a hairs more speed on the landing and you will do fine.
