    everyone who knows me knows how much i've been preaching placing a cooling fan in front of the
    P3P whenever doing a firmware upgrade because of the overheating issues on the P3P gimbal main board.

    ok so get this.
    i have about 20-25 P3P bad main boards in a box and last night i just randomly pulled one out that i had marked with NoVideo, you know the usual P3P issue with overheating (No Signal).
    so i plug it on the assembly with the whole thing, plug it on the bird and sure enough "No Signal" on top of the screen.
    for the heck of it i put a 1.9.6 bin file on the microSD card and do the usual fw upgrade.
    it finishes! at that point i am like what ?? usually bad main board doesn't let you finish the fw upgrade because of the device 15 and 8 not recognized error.
    i turn off the bird, turn it on, turn on the controller, plug my iphone on it. VIDEO IS WORKING!!!!
    ummm WHAT ???
    i had it on for couple minutes just to make sure. power cycle everything again.. WORKING!

    now i am going to have to go through ALL those main boards just to make sure i have more that will behave like this.
    could it be software / firmware issue?

    just wanted to share my findings with you.

    i will try couple more and post more findings when i come to a conclusion.
    personally i think i had a good board marked "bad" but at the same time i am wondering what are the
    chances i grabbed the RIGHT ONE out of that box of all marked not working. :p
