There is no other way to get Auto Trim - you must have the AP Panel

Not quite, Jake. I developed an autotrim controller that does not require panel mounting. Available from Makerplane, called the M-PWR-2AT. Was actually introduced before the Dynon version was released.

Admittedly not as tightly integrated as the Dynon version, but will function as a speed-scheduled trim controller even with an EFIS failure and can be buried in the airframe.
Needs only a pushbutton and a lamp for configuration and stuck trim fault recovery.
