Honestly all I can think of is if you were to get an esc that can handle higher amperages. I haven't seen this thread in quite some time, but now that I see it I remember I was gonna tell people how it flies and such. I've only currently got about 2 good flights on it because of one stupid problem or another, that and lack of time. First my ESC blew, then I got that replaced on warrenty, then the motor blew, and I just got that back last week, but haven't had the chance to fly again, yet. From what I can see though, it flies great, it does have what I would call some mushiness in the controls when you're going fast as you would expect, but it torque rolls really easily. In general it's a great aircraft, especially for learning on, now I don't have to risk my turmoil when I'm learning something new.
