Working on the empennage and researching approach to trim options. Any insight would be very much appreciated!
I'm leaning toward Garmin 3 axis autopilot with yaw dampening. My understanding is you use aileron, pitch and rudder trim to remove any unbalanced control forces.
Once balanced, the autopilot servos take over and do the work of flying the plane and take the wag out of the tail if you opt for yaw dampening. Please correct me if I'm wrong but as I understand it, autopilot servos are NOT designed to adjust for an out of trim condition and the system will squawk at you.
Which leads me to my main question. Can the Garmin autopilot control all three axis of trim AND three axis of autopilot? If that's the case I would assume I would need three electric trim motors and all three autopilot servos?
When I looked up some specs on the GSA28 interface it shows two inputs for controlling trim. Not three. https://support.garmin.com/en-US/?faq=JgjMM09KZw3qmcMthIHNw9
Can the Garmin system in fact control all three axis of trim? Or does the pilot control the rudder trim manually? Options being the pilot meat servo on the pedals, a spring yaw system, or electric trim system option.)
Thanks in advance if there are any Garmin experts out there who can provide some insight into the best way to set up a three axis system.
