Falcon 3D gyro and tail rudder issue

[Gabe]

OK here we go. Got a new tail rudder servo and gyro (the first ones burned out simultaneously for some reason), but man am I confused. When I plug everything in with the tail servo plugged into the gyro, the tail servo loses a major range of motion. In head lock mode it will push the tail rudder out (rotate counter clockwise) almost the full range of the servo. Then, when I press the stick to the right, it has very little to no rotation in the servo. The tail rudder is basically pegged out completely. In normal mode, it isn't quite as severe, but it is still a problem. When I plug the tail servo into channel 4 directly, I have a normal range of motion in both directions.

So do I need to adjust the location of the servo (if so which way?), or is there something wrong with the gyro? Also, I adjusted the gain and it no affect on my range of motion for that servo.

I'm so confused.

When the servo is mounted and plugged into ch. 4 the servo arm should center in the rotational range and the tail slider should center on the slider with the Tx rudder trim centered. If the arm isn't centered then center it and then move the tail boom servo holder until the slider is centered. Make sure the gyro is on "nor" and "reverse", if it has those settings, and the gain set on "0". Plug the gyro back in and you should see the slider creep slightly in towards the boom. This is normal. Then verify that you have full slider movement. Fine tune, if neccessary, with Tx rudder trim.

Happy landing
