I use a IFLY 740B Panel mounted GPS with two AV-30e Uavionix supported by the IFLY Serial Connection. My question is - What Autopilot Model would be compatible?
In my experience, any autopilot that accepts a NMEA input via a serial connection, I have had True Track, Trio, and Dynon - they all work great!
If there is one outstanding feature about the 7XX units besides their stability it is the autopilot connectivity.
