I have a Blade 350 QX3 that I have been flying for a month or so. Tonight there were some thunderstorms approaching and I wanted to get some pics from altitude. In my haste to prepare the drone I must have switched it "on" as I was hooking up the battery. And in my hast I pressed the leads together backwards causing a Spark and a burning smell. Obviously I have burnt something out. I was hoping there was a fuse somewhere. Short of that what would I have destroyed? The drove will not do anything now. No signs of life whatsoever. please help.
If you can get new electronics, there's the fix, but sounds more like time for a new drone. ESC's, main board, or other electronics boards do not like to have reverse polarity voltage applied to them....you have burnt out major components on one or all of those boards and as they are surface mount components they are probably not repairable.
