I had grief when I first installed 3.14 and using the rotorpixel gimbal, not sure if it was the gimbal creating the problems or not, kept getting red lights flashing when doing the calibration had to always do the calibration twice to get it to work,, did a hard reset to the flight controller and reinstalled 3.14 and now everything seems to be working as it should not sure if it was 3.14 that did it or just that the firmware screwed up when it installed, but she works now, just my 2 cents worth if it helps ya make a decision, happy flying
