I've had to rebuild the elevator and rudder three times. The elevator broke at the control horn on the second flight. Not 1 plane, two different badboys. I landed using throttle to control. There was still a small amount of elevator response, but when I got it down, the main stick and the reinforcement for it had broke out two inches on either side of the control horn. On the second plane, I used Sullivan control horns that bolt through the wood rather than the carbon fiber ones supplied. That didn't help. I lost the elevator on the third flight even though I was checking the elevator before and after each flight. The rudders never lasted more than 1 flight without breaking the balsa stick that supports the hinges.

I have since build completely new rudders and elevators of the same shape, but with much more balsa near the hinge line. That helped, but then the horizontal and vertical stabs began to break too. Then I just made completely new tails that were of a more conventional design, and that really helped. I have since retired both of the badboys that I have. I keep them so that If I am really in a pinch, I can put the gear from a crashed plane into the badboy and I still have something to fly. Its kinda like I keep a 'stick' around... If I don't have anything else to fly, I can put one of them together and at least have something to through into the air.

There are 100 other guys out there that will swear that I am all wrong and that the BadBoy is an excellent plane. Maybe that is true for them...
