Ok guys here goes, I had a flyaway back in September. My Phantom 1.1.1 and my GoPro Hero 3 spent 2 months in a corn field until a farmer found it and called me . The firmware is the latest 4.02 . I downloaded the parameters and imported them . I tried the magnet trick without any luck . I tried another compass. I bought a new GPS module and installed it plus a new wire from GPS to Compass. I have been going nuts trying to get this thing to calibrate. Whenever I do the horizontal calibration I get the sold green light. Then after completing the vertical calibration all I get is fast red flashing lights. I have tried about everything I can think of. I have done advanced calibration several times. I recalibrated the sticks . No matter what I do, I cannot get the compass to calibrate. I'm using Naza Assistant 2.20 I'm about ready to send this thing to it's grave .. PLEASE HELP . Thanks in advance ..
