I have had more fun with my Twist 40 than any other plane I have flown. It took me from zero knowlege on 3D flying to rock steady hovers, and all the other stuff as well. For 99 bucks it's a genuine bargain. I power mine with an OS 55 AX - what a sweet combo. I balanced mine at 5.5 inches back from the leading edge, this was one of the best things I did to make it easy to hover. I have other planes, but nothing flies like a Twist.
