I am in the last (I hope) stage of repairing a crashed P3P I bought. My kitchen table ate the screw that attaches the camera body to the gimbal shaft. Spent hours looking with no joy so I'm blaming the table. I bought the DJI screw pack but none seem to easily thread in the shaft. I don't want to force it, so I need to know what that screw size is so I can use the correct one. Tried calling DJI tech support but I was number 17 in line. I only have a Tracfone with paid minutes so I don't want to throw away a couple of hours of my minutes waiting for them. Can anyone help?
