Looks awesome. I'm still trying to figure out if I'm doing the same setup or sticking with GI275s. Of course a GFC500 would be great some day too. How well does your autopilot interface?

The autopilot functions, but is clunky. Steering is through the rudder so it skids around to hold a course or a heading. Any change to the baro setting disengages the altitude hold. As long as you are aware of these limitations, it functions. Zero F/D functions.
But, on the bright side,,, how many Maules have an A/P that will hold an altitude.
