Noisy gyros? hud moving in mission planner while on bench


Weird problem - 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!

  • I noticed this too. To reassure yourself unplug the gps and the hud should be stable, unless of course there is a problem with your gyro/accelerometer.

    This is probably the centrifugal force correction which uses the GPS velocity.  It's likely only visible when you're in doors with a not-perfect GPS signal.

    • great - thanks!
