Yes I have one and just took it off my Cap 232 H-9 I flew her with it for 3 years and still has lots of poop left in her just that she is a bit on the heavy side, My best performance for 3D type flying was with the Lanier Laser she would hop up and down on the prop all day long just have to put all your weight to the rear of the plane... Now the Mac has been retired to a 1/3 Balsa USA Sopwith Pup to fly at about 1/2 throttle and get a break from some real hard flying in IMAC the last 3 years....
and that the rest of the story.
