Being as there is no serial no. on the camera/gimbal, do you use the serial no. on the main craft underbody as the other half of getting a QR code. With all the extra "goodies" inside the shell, I am assuming that the range extender serial no. and the main body serial no. are all that is needed to get a QR code, IF you need to replace the range extender. I have gone through 2 cameras, with a third on the way, to have a working "your flying camera" P2V+. I'm beginning to think I stepped into some big doodoo getting involved with the "plus". So, far, two birds, no working cameras. Thanking you in advance!
