Speed-Sensitive Trim

Piper J3

Well Known Member
I?m trying to help a friend who has dual Dynon HDX in his RV-12. The airplane has autopilot with knob panel. Elevator trim is very sensitive at cruise speed.

Question ? isn?t there a function for speed-sensitive trim in the HDX such that you can have slow trim speed when airplane is in cruise and fast trim speed when airplane is flying slow?

I?ve searched HDX Pilot?s User Guide. Can someone point me in right direction?
 
Download the Installation Manual:

SETUP MENU>HARDWARE CALIBRATION>TRIM CALIBRATION

It's the same for either the SVT or the HDX with the AP panel.

Tony beat me to it ... section 8 of the instillation manual has all the info you need.

Also of note, when using the AP & Knobs panels, the setting for the autopilot needs to be set to the expert mode.
SETUP MENU > AUTOPILOT SETUP > AUTOPILOT CONTROLS > EXPERT
