Default TAIL NOT HOLDING IN FLIPS

Tail swings to the right when I do flips. This is new, with no changes in setup.

Raptor 50 SE, O.S. 50, 401 gyro. Head speed governed to 2000. One day I was doing nice flips, next day it consistently lost heading hold during flips. I can jam the collective to full positive from a hover and rocket straight up with solid tail hold. But not during a flip. Any suggestions?

Quit feeding left rudder in when you flip

Inspect the belt, make sure everything is smooth and slop free in the control system and have someone watch and see if its you or throw some expo in the rudder.

I run 20% expo in the rudder. Maybe i'm getting parkinson's. Thanks for the suggestions.

OK, I have found the main blades very slight out of track, one turn required at the swash end made for perfect. Turned the gyro gain from 50 to 75 and have no tail wagging. made these adjustments at home. Will see what happens when I get to the field.

Also noticed what sounds like a substantial increase in head speed when collective is pulled back to mid stick. With my multi gov this should not be. I'll study this some. Any more suggestions?
