Does anybody know why the RC led is green. It was red. This is a new phantom that hasn't been flown yet. Upgraded 3.04 to 3.06 & installed Zenmuse H3-3D. I've gone through several calibrations on the phantom & the RC plus tried sync process to no avail. I've spent a day on this forum & working on the phantom but I can't: 1. Get the RC led back to red. 2. Can't get sync process to work. 3. Can't get motors to start.
