Kiss 4in1 ESC Repair FAIL :(

Started to repair some broken KISS 4in1 ESC's received from you guys, but I had some interesting surprises :) Again, my opinion about 4in1 ESC's is getting true. Even if there is a simplicity in the building process of a quad because of 4in1's there is no doubt about the downsides of using 4 esc's on one board... if one goes they all go(and an esc will fail one way or another) when you could have had the chance to replace the broken esc and go fly again with way less money involved :)
