I just bought a used P1. When I power it up, It flashes green 4x, then green every second, like it has satellite lock, BUT it never flashes red, green, yellow on power up. It never asks for a Compass calibration either. It just keeps blinking green. I've updated the firmware, transmitter calibration, motor test via the Assistant, and everything else. The person I bought it from stated that the compass had been magnetized. I'm going to order a new one. I've tried to see if I could get a reaction by trying to fly it manually, but nothing; the motors won't even spin. I move the sticks, the LED does flash green 2x. Just wondering if anyone has ran into this issue, and what the fix as.Hopefully I am just looking at a bad compass module.
