I've just fitted a new compass to my olipan as the previous one gave very random values. I know it works as when fitted to my Arducopter it does what it is supposed to and gives the correct headings and nice smooth value changes.
However when fitted to my Arduplane it is not working very well at all. Here are some typical values when pointing at the cardinal points:
N 279, xyz 18,80,103
W 241, xyz -108,226,108
E 155, xyz -151,-62,105
S 197, xyz -249,85,110
These values are about the same whether the APM is in or out of the aircraft.
This doesn't seem quite right to me!! Anyone any suggestions before I reload the Arduplane software - I am using ver 2.24.

The magnetic signature has changed, try erasing, resetting and re-initializing your board. Then try to move the compass module further away, there are instructions in the wiki for how to connect it to the IMU board's molex connector (I believe this is a serial I2C interface). You can order quite long connector cables from the Drones stores.
