OK, here's an update...
I went out yesterday to attempt some more tests and managed two flights totaling about 37 minutes as well as some tests with a third battery on the ground -- no props. I have already uploaded the exposure tests I preformed on the ground
but this update here is about the camera gimbal problem I mentioned in the OP (items 1 and 3). I had to cut that first trip short because of the gimbal homing issue and on the next trip I encountered the problem about 3 more times. What appears to be happening is that the camera tilts up to what looks to be the upper limit then tilts down to the lower limit with the camera actually pointing down and a little behind -- about -115 degrees if horizontal is zero. But, as it's tilting down it hangs up at about -100 degrees and is unable to complete the downward homing action. It then goes back to the upper limit before hanging once again at about -100 and then continuing this without end. When I look at it with power off and move the camera by hand I can feel it hanging up and if I apply a bit more force it snaps past there and I can continue to the lower limit. I do not have to apply much force here so I think it's just a torque limit on the motor. When I watch closely I can see that it is the ribbon cable that is hanging up on something and when I push past and the gimbal snaps past the point I can see the ribbon cable kind of 'oil can' -- it must be snagging on something.
OK, so I could try to dig into this but if I mess something up in the process its on me so I called Newegg today about it. When they finally called me back 2.5 hours later I explained the problem and asked what I should do about it. The woman told me to send it back and they would review it and they might have a replacement in a few weeks. I was unhappy with that and told her I would return it for a refund and she put me on hold to complete the process. While on hold I went to B&H and ordered an 'In Stock' P4P which I should have Friday. I had completed the order before the woman at Newegg came back to finish the return song and dance.
Let's hope the new one is free of those defects and doesn't introduce new ones. With DJI it's a crap shoot!
