To clarify. When you had the servo plugged in, did the servo swing from end to end when you changed modes ?
If it stays at one end of its travel and just moves a bit at that end then you are not actually changing modes with the TX. I assumed you used a servo that had the arm centered on it before you used it too.
One very handy gadget I use when helping mates setup their gyros is my 'servo tester'. This eliminates the TX so you can prove the gyro is behaving first.
With the gyro gain input plugged into the tester, the gyro should indicate HH Mode at one side of center on the knob, and Rate Mode at the other. Obviously the gyros other cable needs to be plugged into the model or another tester to receive power and a rudder input also.
