Trying to help a friend with RV-12 dual HDX with Knob Panel and AP Panel.
Everything good for 200TT and the last flight had HDX warning that AP Panel OffLine. And, sure enough, it was. The stabilator trim not functioning either with the manually operator trim switch. Were are told that stab trim goes through the AP Panel. I would think the trim would fail "safe" and keep functioning, but apparently not.
We have checked fuses and re-seated subD connectors to no avail.
We suspect the AP Panel gave up the ghost and needs to go back to Dynon for some loving care.
Any thoughts appreciated...
