Sure, I've flown mine several times...busted it up on a tree branch, rebuilt it, and flew it some more. The .020 is PLENTY of power for it, I think a .010 would fly it fine. It stunts pretty well, just a little mushy in hard turns. My biggest problem with it is the miniscule tank on the .020, maybe 30-sec. flights. No room for an exterior tank. I'm thinking of building a little bit larger version (King Bee?) with some fuselage space dedicated to a tank.
I'm using 15' lines because that's the limit in the space I have (my back yard). I have hit a tree branch with the QB, a Lilac bush and the garage eave with my ShedDoor. Gotta learn not to wander even a little!
