I dont have an equal range of motion with my tail servo, and it forcing me to have my limits on one end in the 45-60% range and the other end in the reccomended 100-120% range. With the gy601 or any gyro from what Ive read, both limits(left and right) should be between 100-120% otherwise you run the risk of burning out the servo. I have tried several different linkage set-ups and it all seems to revolve arround the throws being off. The servo is the futaba s9251 that came with the gyro.

Please help

B,

Adjust the tail linkage (segment from servo horn to pitch slider ball) length to center the range of travel (put the gyro in rate mode to keep the servo centered during this process), then change the hole used on the servo horn to adjust the mechanical travel range.

gyro help

Im not getting equal throws on my servo. In order for everything to be by the book. My limits in the gyro are very far apart. Or my slider is off center, or I don't have full range of motion on my tail rotor. Is there anything I can deviate from?

1) Reset the endpoint settings in your gyro and put it in rate mode, this insures that it commands the servo to be centered.

2) If the servo arm is not at a 90 degree angle to the rod, remove the arm and put it at 90 degrees.

3) Adjust the linkage from that tail servo arm to your tail so that the tail slider is centered, do this by adjusting the length of that rod

4) See how the endpoints are, judging by the endpoints you had selected to begin with, it should be pretty centered

5) If endpoints are not enough or too far, you can move the ball in or out on the tail servo arm.

Hope that helps, it's kind of difficult to explain without having something to point at. If you really need help I'll make a youtube video .

I'm going to guess that the servo horn was put on the spline without the servo being neutral to begin with. Plug the servo into the rudder terminal on the rx without the gyro and make sure there's no sub trim and no regular rudder trim. Null the rudder trim after you're sure it's centered then follow the previous advice. PS make sure while u have it plugged in that the servo is working in the right direction.
