Thanks Jason,

I tried to pull nose up to a 90 degree and then bring it back down a few times before going all the way over. I had control for a few up and down pulses of the collective (over control), then it came at me a and I panicked.

Funny thing is, I went to a hobby shop that had a couple flight sims and tried to fly them upside down and had the same results. Lost it after a about 15 seconds and crashed. I can fly the FMS inverted, but it is while using a Microsoft Sidewinder Joystick. The tail is controlled by twisting the joystick instead of left and right stick input. I think concentrating on the other hand (left instead of right) and the lack of a HH gyro freaked me out. Now, I'm afraid to try again without getting a TX for the sim.
