My DIY Quad X - Solved compass interference for MultiWii SE V2.5
My MultiWii SE V2.5 board install near ESC power supply wire, then i found a big problem.
a compass sensor on this FC(Flight Control) board was interference by power wire.
while throttle-up, compass sensor measure wrong about 30 degree.
So, i decide to use external compass sensor instead. it's work well,
yes i can solved this problem already.
at first, i must disable compass sensor onboard MultiWii SE V2.5,
then use compass sensor on GPS module instead.
HMC5883 compass sensor on GPS module, it have good ground shield and good location, it don't have any interference.
and because of it's same compass sensor number, so i don't need to modify any firmware code. (it have same I2C address)

GPS Return To Lunch (RTL) need accurate compass sensor (magnetometer).
if compass sensor was interference, GPS RTL can't work.
This video show, GPS Position hold and Return To Lunch,
both work well with accurate compass sensor.
