I have one. I think it flies great! It is not for the faint of heart...But it will do whatever you ask of it. Torque Rolls, Hovering, Waterfalls, Blenders, Inverted Flat Spins , etc. I have been real tough on mine. I had an engine flame out in a hover less than 10 feet off the ground. The only damage was a broken prop ( well it bruised my pride, but that doesn't count). It is a very well thought out design. Light, but very strong. $99.00 - Buy it!
