Autopilot
Thank you all.....I have a lot of excellent suggestions and great advice. I'll get on it as soon as the outside temp gets above zero here!

Thank you Joe. Worked fine until this Fall. Had the plane now for 3 years. Maybe pilot error ? I push "level" and it turns.

Tony. I'll try "level" with the plane in the hanger with the motor off?
Thanks for the advice.

I don't think I'm in the expert mode. Just straight and level

Bill, I don't see anyplace where the servos are located.
Great idea to find a "test mode" but I don't see rear either in the Skyview manual. Maybe in the RV manual?

Look in the Skyview manual. You can download it from the Dynon site.

Look in Chapter 10 of the Skyview Installation manual for AP Servo test mode and calibration instructions. The test mode will move the controls to the fore-aft/right-left limits, it the movement does not look correct you can recalibrate the servo-control position. You can also monitor the servo position feedback as you move the control stick, if the numbers change and the range is consistent the servo mechanical connection is most likely fine. The Dynon AP Inflight Tuning Guide might also be helpful.

The pitch servo is under the pilot seat pan. The roll servo is behind the baggage bulkhead. You can familiarize by looking at the plans section 44A.

You say the aircraft turns when you press the "LEVEL" button? That doesn't sound good.
The Dynon SV Installation manual ( http://dynonavionics.com/skyview-documentation.php) has all the procedures for installation, configuration, calibration and includes a test of the autopilot servos. That must be what Bill was referring to.

To test, hold button 7&8 together to enter setup. Scroll to the bottom to Hardware Calibration. There is an option in that list for auto pilot. Select test and run the test following the instructions on the screen. If that works, then the shear screws are probably fine. If not, then replace them. If it works, but not correctly, then another options in the list was Calibration, which you go to and follow the instructions on the screen to recalibrate.

Have you done any software updates since this fall? If it stopped working after a software update you may need to recalibrate it.
