Wow! That is lucky.

My G410T is working okay in both heading lock and rate mode. I'm not impressed with the heading lock performance yet because I get a very slow drift in the heading requiring a control input every minute or so. Maybe I'm expecting too much... I have the gain at 100% and no oscillations.

All I can suggest with my limited expertise is that you need the right combination of gyro reverse and transmitter reverse to make it work right. It would drive me crazy knowing I had to have the TR spinning in the "wrong" direction. Good luck!
