If I am reading that right Matt your flipper lifts your machine into the air along with the opponent?

If so then whats the point? You wont be flipping as quickly as you have to lift 26kg instead of 13kg.

If I am wrong could you put a pic on your profile of what you have in mind?

Dave if I was against such a machine in the arena I would just wait until you got bored of spinning on the spot and then attack. Granted you may get some action in a large melee but I always think an offensive weapon is better than one which relies on the opponent doing something. Best of luck.
