Hi,I'm facing a strange issue with APM2 GPS lock. The blue led of the GPS shows solid 3DFix and when I connect the APM2 board via USB to my computer Mission Planner says also "3DFix" as expected.Now when I connect the battery, as soon as power is…

Is it normal that the APM2 board roll value shows about 3 degrees deviation from 0-level in the MP when the board is horizontal and level on the table? Pitch value seems to be normal around 0.
