XTreme autopilot slow airspeed limit?
Posted: Fri Nov 03, 2023 8:44 pm
I have a Gen 1 XTreme EFIS with MGL servos in my Zenith STOL 750. I flew for a long time without slats and my cruise was about 80 kts and the AP did OK. Later, I installed the slats, bigger tires, etc., dropping my cruise to about 72 kts. With the AP engaged, it now banks back and forth and it is very annoying - the only thing that has changed is that my cruise speeds are lower. Is this plane's configuration now just too slow for an autopilot?
As far as the AP's configuration, the bank servo's pushrod is connected to the most distal hole on the servo arm, target rate of turn is 3.0, servo torque 80%, servo magnitude 20 (the manual says it goes to 30, but it only goes to 20 on my setup page), and heading control medium (although it still does the same thing with fast or slow settings).
