Compass Sensor Placement

[slugger]

Just added carbon fiber landing gear to my Phantom. Does the position of the sensor mounting on the landing gear make a difference(height, angle etc)?

Thanks

Angle matters, should be in a plane parallel to original location, geometrically speaking. Don't think vertical location matters.

Most definitely! Slight angle error will result in circling. Dramatic errors will result in run-away! See following thread ultimately caused by the compass getting installed rotated 180 degrees.

I have fitted 3d printed landing leg brackets from Shapeways, which are great. I thought I was going crazy because my Phantom was often behaving badly, and recalibrating it didnt last long. The cause was that the compass fitting on the leg tube is only a fr
iction fit. It was being moved either by clumsy handling on my part, a bumpy car ride or a bad landing. I fixed it in position with a small self tapping nonmagnetic screw and now it stays in calibration properly. My compass mounting plate only lines up horizontaly and vertically in one place on the leg and so I fixed it there.
