centering aileron electronically
 

I am building a SIG Four Star 60 and I am at a point in the instructions where I am supposed to center the ailerons electronically. Is this as simple as plugging them into the receiver and powering it up with a battery? Or is there something more to centering ailerons electronically? Thanks in advance for any help[sm=confused.gif]

Yes, there is more. You also need to turn on the transmitter and center the trim.:)

That's all there is to it--plug the ailerons into the Rx, (with a battery) and turn your Tx on, The servos will go to neutral, or their center. Make sure your Tx trims are also at center. This allows you to set your aileron linkages so the ailerons are even and neutral also, then once you fly it, you can adjust the trims on your radio for proper flight performance. You'll also do this with your elevator and rudder servos.

Turn your radio on and check the position of the servo arms. They should be 90 degrees to the servo. If not, unscrew then, pull and try to get them centered. After you get them as close as possible with the splines on the shaft. go to the subtrim function on your radio and center the arm exactly. You should have the trim centered to do this.

If you're using a Futaba radio, don't cut all the arms off those servo horns just yet. Once you get the servo centered electrically, I.E. as has been explained in previous posts, install your horn of choice. If the arm is not exactally 90 degrees to the servo, then remove it and try another arm on the same horn. Futaba offsets the splines so none of the horns lines up in exactally the same place. It enables you to get the horn exactally where you want it without resorting to the radio to set your subtrims. Kind of a throwback to the days when radios didn't have subtrims.......

I don't know if this works for any of the other MFR's though....

I'm using GWS servos on a plane that's under construction. Similar situation. Arm would not line up exactly centered. Removed the arm and rotated it 180 degrees (almost), centered correctly.
