I have absolutely no problems with my Twister. As a matter of fact its about the most reliable plane I've had. I went with two elevator servos and the rudder servo all in the tail. It does hover with a saito 72 but pullout is very sluggish. Does the prettiest spins I've ever seen. Has a tendency to snap with an abrupt elevator pull at low speed, but it doesn't have the really fat airfoil that a true 3D plane has.
BTW I bought it to replace a Hangar 9 Aresti. Even though the Aresti was supposedly a pattern plane the Twister tracks much better.
