Garmin autopilot

Recommended Posts

This is just some info on a Garmin autopilot.

I just installed dual Garmin G3X touch screen EFIS systems in my SW and it has been great. All G3X systems contain a very sophisticated autopilot which can be operated within the EFIS or with a separate analog stand alone analog unit. My CT had a Trutrak autopilot however could not be integrated with the G3X. I had been thinking of installing the garmin servos for some time to take advantage of a much better autopilot. I discussed this with Garmin and they said that the servos would not work in the CT. Prior to talking to Garmin I had extensively researched the drawings and torque forces of the servos and was sure they were wrong. I purchased the servos and panel control unit and was able to easily install them in the original brackets,  everything fit perfectly and with the Can Buss data system only 5 wires per servo . The roll servo does not need a torque enhancer due to the servos having 60 in lbs of torque as opposed to 30 for Trutrak. Also the Garmin servos have 0 force resistance when not in use which makes the flight controls lighter. The flight tests went very well and the  autopilot has functions only found in very expensive high performance aircraft. According to Flight Design I have the only CT to have this system.  I am posting this to inform others that this is another option for at least ELSA.

Considering I am the only one to do this install I can assume that there is no current approval however I am sure it could be done. The only G3X unit that fits on an sw is the 7 inch.
