So... My first P3 Pro came with a broken controller. Sent it back to DJI and ordered my 2nd from MultiCopterWarehouse (those guys seriously shipped fast). Second one arrived with everything undamaged (bonus) with the exception of the gimbal protector was floating hanging off (just like the first) and the camera had odd sticker/tape residue on the bottom and side of the camera. I noticed that one of the motors also did not have the warning sticker over the spindle, but I couldn't find it in the box. Regardless, I inspected everything and all looked well. First day was rainy so I upgraded firmware and left it. Today was perfect so I decided to fire it up. Did IMU calibration and then compass. Everything looked good but I noticed one of the motors seems to not be as free as the other three, very slight binding. At this point I was kind of pissed since the first one was broke on arrival. Threw the props on and decided to see how they'd spin outside, not intending to fly if it didn't run right. Fire it up and, sure enough, 3 motors start, 4th motor starts then stalls. Rest of them shut down automatically. F. Spun the stuck motor a few times and tried again, this time all four spin fine. Take it up a couple meters and let it hover for about 5 minutes and all seems fine. Took it for a 10 minute flight back and forth around the neighborhood and seemed to handle fine. Question being - has anyone else noticed a "sticky" motor? More curious than anything... Leery of DJIs first round of build quality based on the less than stellar packaging. Beyond this I have to say this thing is far nicer to fly than both my original 1.1.1 and P2V, nice upgrade comparatively. And the P3 controller is phenomenal, love all the physical buttons for operation. While I've had to look down quite a bit to make sure I was doing the right thing the layout is great and I like the feel in hand - even with a Nexus 7 stacked on it.
