I don't have any control forces on the yoke or pedals. Before I did my original post, I tried trimming the Ovation straight and level and when I push the autopilot wouldn't go on. What does happen is AP flashes, YD goes on and whatever other settings, usually roll and pitch. I will try again with straight and level flight, trimmed out, with my hands and feet completely off the controls.
Just so you know I am a real pilot and have been using XPlane since version 8. The G1000 autpilot in the Ovation 3 works fine, the stec 55x in the stock 172 works fine. Like I said I am stumped.
