I finally got round to upgrading latest firmware (3.12) for the phantom. All went ok. Calibrated IMU , test flight ok. IOC mode and failsafe switch all worked as it should.
I never managed to re calibrate the compass though. The range was in spec so wasn't too bothered
I've since tried again (and failed) as I want to upgrade my transmitter and wanted to check i can get all the functions first.
Switching GPS / Atti switch back and forth doesn't seam to do out ....... Is there something I'm missing , is compass calibration different with the new firmware ???
If anyone could help , would be most grateful
Cheers in advance
