Sorry, but there is something fundamentally wrong with the Kiowa code. I've hunted high and low and I've never been able to find the problem. It has something to do with the single engine power code which was customized for the Kiowa by one of the previous modders. It's spread out through so many modules it's hard to trace. I just don't fly the Kiowa anymore. Sorry about that. Was the Kiowa the one that flipped out with "main rotor damage"? That's the only helo in the sim that I know of that has a physics problem.
