aartsf said:This is the only picture on the entire forum (posted xx times) showing that. This is guestionable picture though. A picture without a story, showing seemenly non-factory soldering and a suspected soldering-drop nearby the sticker. MacCool can you enlighten us on the whereabouts of this picture you posted at numerous places on this forum without any background information?!
Nah, I found it on DJI. Someone posted it as an example of burned FETs. I happened to notice the same blue mark that I have on my incompatible ESCs. Obviously the guy detached the motors, likely the reason for the globbed solder.
It's a picture of burned FETs with a blue-marked capacitor. The picture speaks for itself. I understand that people desperately want to believe that their factory-defective Phantom is ok, but let's be real. The blue capacitor theory is ********. A rumor reporting a rumor. A guy posting on the internet about something that some "DJI tech" told a hobby shop employee. Even if that unlikely story was true, it's not like we all aren't aware of the widely varying information and ignorance that we get when we call DJI, right? In the meantime, we have a document, directly from DJI, that clearly states the markings and level of compatibility between various ESCs. You would rather believe that an actual photograph of burned ESCs with a blue-marked capacitor is somehow contrived, when you already have all the information you need printed on a nice, full-color brochure right from DJI. What is it that you're so desperately trying to convince yourself of? You're trying to parse out every little nuance from reported internet rumors. I can't imagine a more fruitless effort.
Here's what you need to know:

It's right from DJI, even before they came out with the new (current) IC driver firmware 4.06 and there was no ESC v2.1. And you want to somehow believe that a guy telling a guy telling another guy about a "blue mark" on a PC board component and then posting it on the internet somehow supervenes their previous formal corporate announcement about this very issue? Seriously?
