RE: Hangar 9 Twist 3D
I have G3 and if my yak flys anything like the yak on it I'll be just fine. About the only thing I can't do is a rolling harrier and it's very close.
While the twist stalls a bit slower due to the thick airfoil, the yak shouldn't have as much coupling. Once you figure out where to put the left stick you can knife edge the twist just fine, but it is kinda touchy and I'm not willing to do it down low yet.
I wish there was a more twist like plane for G3, that way I could practice more, but everything on G3 flys very different.
