Hello,

While the plane is on the bench, the hud is constantly moving. I have calibrated gyros multiple times and it still continues. what could be causing this?

Here’s a video:

APM 2.6 + gps/external compass
3DR power module
Plane 2.78b

any help would be greatly appreciated!

Completely normal. This is the AHRS algorithm using GPS to subtract off acceleration from the accelerometers. The noise is because the GPS is indoors. There will be less (nonzero) noise outdoors. If it offends you a lot you can reduce AHRS_RP_P.
