Well I maidened mine today...few miutes ago. I was not very impressed to say the least. I set all throws to factory settings. It does not respond very fast to any inputs. I believe it's the servo's causing this. It does not fly very fast like I once thought. It is not very stable in flight either, it likes to flutter a bit. I flew it with a 1100 3s and balanced it perfectly. Upon final approach I found it real hard to get the nose to stay up. I didn't want to touch down with the fan running for abvious reasons so I dead sticked it at the last second about a foot up. It did a cartwheel and broke the vert. stab and one of the mid stabs. They glued back together real easy and straight. I think I am going to fly it once more to check and see if there was anything I missed while inspecting it and then sell it. I have too many projects to beef up right now to add another.
