Have the Dynon servos changed lately? That is one important consideration in evaluating an autopilot. I'm running Dynon servos off my D180 (and HS34) and despite upgrading to the biggest servo available, it still will not keep the nose of my Rocket on the horizon in a 180 degree turn. No matter what setting I use, it just does not have the muscle to maintain altitude. Also, the Dynon servo's geartrain is always engaged, so there is always the drag of the servo even without the AP engaged. Another Rocket buddy had the same problems with his Dynon setup and switched to G5 based Garmin AP and the performance issues went completely away. Night and day improvement, he reports.
I'm less concerned with the user interface than I am about the system making the airplane go where its supposed to.
I'm switching to Garmin.
