在DJI S800 里面发现红色的ESC RC信号分配连接器引脚焊接头是松散的。。检查发现在# 6电机连接器不正确焊接到PCB的接地和信号引脚。你可以看到，没有证据表明焊料引脚上。如果你把“控制器”贴在你应该注意引脚稍凸的充分的焊料的印刷电路板。如果他们不那么插脚可能不会作出适当的连接。好消息是可以简单的测试和修复。 用镊子轻轻要动在每个销是否松动。如果你找到一个松散的销我们建议删除红连接器和所有的销和新的报头引脚取代和消除红连接器。
We have found on our DJI S800 Spreading Wings hexacopter that the header pins inside the red ESC RC signal distribution connector were loosely soldered. We had a motor fail about 1 minute into running (just hovering, no damage thank goodness). Inspection revealed the Gnd and Signal pins on the #6 motor connector were never properly soldered into the PCB. You can see no evidence of solder on the pins. If you peel back the ‘Controller’ sticker on the PCB you should notice the pins slightly protruding with sufficient solder. If they are not then the connector pins may not be making the proper connection which is what was the case with ours.For the time being we feel it is very important to do the following on all DJI S800. The good news it’s a simple test and fix.

If you find even one loose pin we recommend removing the red connector and all the pins and replacing with new header pins and eliminate the red connector. Failure to check this would lead to a failed motor in flight if any of the pins should come loose.See the pics below of what we found. Notice picture one shows the two pins that fell out from the connector.
What we used are 8 of these below. The ends extend all the way through the PCB and when soldered make a proper connectio
DJ, Where can I get the pins that you used to replace the red connectors on the S800 that you repaired? Would you suggest that I replace all of my connectors anyway to be safe? Also, I haven’t had a chance to take a photo of my broken gimbal (MKTR Pro) for my F550, if you remember I emailed you last week because I had an accident, I will try to do that today. Thank you for putting that post up, you’re probably going to save a lot of people from destroying their machines!
Best regards,
Steve Powell

You can get the header pins at any electronics supply house. Digikey, Allied Electronics, Jameco, etc. You want three position, single row 0.1″ header pins. eight of them. As for your mkTR Pro, send over the pics when you can and I’ll give you a cost for the repair parts.
Regards,
DJ
