I got a Jumper x86 from Banggood and immediately swapped out the reportedly crap props for Gemfan Hulkies. Tried it for less than 5 minutes. Still power left in my first battery! All of a sudden, a large puff of smoke appeared coming from the middle. Now, it will only beep 3 times and does nothing. Not much to see, but Banggood requested a video. This is all it does and there ain't getting it to do anymore! I don't see what this will show you, but here it is. I already sent them macro pictures of the flight control board and the holes in it from it smoking.
