Most electronic assembly items like that are done with a small electric screwdriver, which has auto torque for that particular assembly, determined by screw size and and base material. They load them up and zip them in. Usually the employee's are rated based on output, and although you would hope they would take the time to get the screw they just dropped out of the assembly, it seems often they just reload and move on to the next one. If I was assembling bits 6 days a week, I might not care that much either......
With the big push to get inventory for the Big Picture, QC may have only been able to do spot checks on batches. The scratches on the gimbal show they didn't even shake the packaged drone to simulate shipping, or even ship a few boxes back and forth. Everyone knows how the package handlers treat packages, so that oversight is troubling, since it seems so obvious.
I'm still planning on buying a
M2P on Amazon, but won't be surprised if I send it back, and at this point almost expect I'll have to. Thank God for Amazon... I went through 3 MP's to get one that functioned perfectly in all aspects. Even though gyro and compass checks can appear OK, there seems to be a variation in consistency and repeat-ability. Such is life with mass production I guess.
If the extra screw has loctite on the threads, that may indicate it was meant to be mounted in a metal base or plate. I'd like to hear Thunderdrones input on this, since he has so much experience with DJI hardware. Definitely not trying to bring anyone down, and I was really looking forward to getting one. It was even my motivation to work extra overtime.
