I am using an mRobotics Pixracer with Arduplane 3.8.2. I’d like to use only a single external compass on a flying wing. Can someone tell me exactly what the setup in Mission Planner should be?
In the Mission Planner GUI I have:
Enable Compasses = checked
Primary Compass = 2
In the Compass #2 box I have both “Use This Compass” and “Externally Mounted” checked, and no rotation.
Below is are excerpts of the compass section from the parameters file. I appears that both compass #1 and #2 may be active. Am I reading this correctly? If so, how can I turn off the internal compass(es)?
While this setup achieves an accurate heading, I get ERROR COMPASS VARIANCE alarms whenever I turn the plane. I think tow or more compasses have conflicts.
How do I disable the internal compasses on the Pixracer?
