today I ran through the compassMot and just was a little stunned at my 60% precent result. I made up a little board to go under the apm with 2 layers of foil in it thinking that would give me some shielding but I was only able to get 50%. I made sure the hexcopter could not move at all. my apm 2.5 sits 25mm above a PD board and perhaps 50mm diagonally away from the esc's. I mean it flys well and hovers nicely, but a little improvement is always good. any suggestions would be hugely appreciated!
regards

Hi,
only things you can do is move your compass further away from you power board or add some mu-metal under your apm (normal copper will not affect the mag field much)
you might get a 20% improvement with the mag shield, but it also lowers your earth mag field a little.
I tried this one with good results before I got an external compass:
