Trim readings when flaps are up

[Belly3870]

When my flaps are down the aileron and elvator trim indications at normal. When I put the flaps up the aileron indication goes full right and the elevator indication goes full nose up. When I start putting the flaps back down the indications go back to normal. I'm running a VP-X Sport and a Dynon Skyview EFIS, and the trim readings come from the vp-x.

This sounds like you have the flap position indicator wired wrong and it's shorting out the power supply on the VP-X, which will cause other analog readings to drift. This will happen if you swap the signal wire and a power wire on a potentiometer.

Does the flap signal move at all as you move the flaps? You probably need to look on the VP-X tool to start.
