Trying to install my Futaba receiver in the P2 V2. The copter had been to DJI for warranty repair. They removed my Futaba receiver and installed their DJI receiver back into the unit for testing before they shipped it back to me. ( It's ok - they covered repairs for a bad crash) SO _ I'm watching a tutorial on which plugs to use on the Futaba ( It came installed originally, I didn't install it). The plug arrangement in the video doesn't match the ones I have. Copter has been flying perfectly fine. In the video the plug going to the main board is X3, with X1 and X2 going to the stock receiver. In my copter , the plug going to the main board is X1, with X2 and X3 going to the stock receiver. Any idea why these would be different ?? Thanks !! Sample from video first , then my copter at bottom.
