sounds like the trim switch itself may need to be replaced.

I would put that trim switch in the tail trim. With an HH gyro you don't use it anyway.

subtrim may also still be usable... Or just do it mechanically anyway. Once I have the bird trimmed, I move the trim from Tx to mechanics to make the Tx trims centered anyway. I only use them as a place holder for what to do when the bird lands.... Then adjust, re-center, and repeat. Only with a broken trim, just remember what you need to do and re-test after adjusting mechanical.
