I have one and it flies very well as far as fun flies go, but we an expensive plane to put together. (8 digital servos). I also have the Sig Mayhem which costs half as much, looks much better and flies just as good. If you are looking for a large fun fly to learn 3D basics with (torque rolling, hovering, rolling circles and such) consider the Mayhem. Since I got it, the Fun World 3D has become a hanger queen.
