I ordered mine from tower and put an O.S. 52 four stroke. I was worried about how it would fly after flying my buddies wih an Thunder tiger 46. Turns out I had nothing to worry about it weighs a couple ounces less than his and has nearly as much pull with a 14*4 APC. I love a move i call the vertical blender. It doesnt have the wow factor that a normal blender does but I like it because the plane will flip and flop and spin and not have any altitude change. It is pretty cool. Anyway Im sure there are more capable 3-D airplanes but none are as cheap as this one. It is the best 100 bucks ive spent in a while.
