This summer, I progressed from flying my trainer (Midwest Aero-Star 60) to a GP Big Stik, and then to the Stinger II. The Stinger II is a fantastic airplane! OS. 55ax and it is really fast, will do any aerobatics you care to try (I don't do 3D), but slows down nicely, and lands like a ***** cat. I like the Stinger II so much I am going to buy a second one to have on hand just in case. (you know what I mean he he). The Stinger II makes me look like a much better flyer than I really am. Just my 2 cent worth.
