RE: JR XP6102 and GY 401 set-up
I have no information on setting up that gyro. I personally would recommend only using the gyro in tail lock. If I'm not mistaken, the HH vs rate mode with that gyro sets through the gain, so values above 0 will be tail lock and values below 0 will be rate mode. So you will just need to use travel adjust and/or mixing to set the gain as desired.
