I didnt use autopilot. i only used combat trim for a few seconds to get aileron and rudder trimed while inverted then turned if off and went full donw elevator trim.
believe me i can do it without trim. i just used it cause it was handy. I'll do it and post a film of it in about 2 weeks when i get down moving.
