The Meyers 200 does have electric trim available as an option when installing the Century autopilots such as the 2000. And, it’s been installed in the latest Garmin installation just last month.
Peter, your plane originally had the Brittain autopilot correct? The Century A/P is a very different installation since its servos are electric instead of vacuum operated. Stein wasn’t aware of the Century installation when he installed your Garmin system.
My original Meyers 200 had the Century 2000 A/P but with no electric trim so it would just alert me when it was out of trim. It wasn’t that big of a deal either. My “new” Meyers 200 has electric trim, and so do most of the more recent Century 2000 installations.
