Hello:

I have the Aerosky APM 2.5 flight control and am installing it in my Quad copter.

It came with zero information so I am struggling to get info bit by  bit.

What I do not have is info on the LED's.

The led that attaches to the compas/GPS unit and the red/blue LED on the APM.

Can anyone provide info as to what the LED colors mean?

Thanks
