My experience with BK support (Brake-Fade)

[Dafni]

Well, well, Folks. Many of you know the story. We already talked about it a few times.
BK's ESC, the Warrior 9918, is a great controller with a reasonable price. I have two of them, and basically I am verry happy with their performance.
BUT, as you might know, one in hundred (or so) warriors shows this ugly phenomenon called Brake Fade. It's when your brakes say bye-bye when the controller gets warm (warm! not hot)
One of my controllers shows this nasty behaviour, and this annoying feat was already responsible for quite some wreckage.
Apparently, some electronic component has some inconsistency, but is still within the specifications, and it looses its performance once its warm

Well, after some long discussion with BK, they say the problem is in the IC chips. They say there is a specification variance on these parts (not controllable) and if the ICs are on the low end of the variance, this will happen. Dafni, I mentioned your similar issue as well (they remembered your name). I think I may be able to get them replaced (and hope for better ICs on the replacement).

So before Mike got this usefull information out of BK, I sent my bad ESC in for "re-programming". The guy who answered my mails told me it will only take 48hours.
Okay, after request I was told there's nothing wrong with it (and no explanation) I just must have ran it too hot. Strange, though, because I told them if I install another 9918, it works fine on the same setup.
So the BK guys sent my controller back, without modification. But, apparently they forgot to add the papers for the custom, so at the moment my package is somewhere at the swiss custom:M:

Then I saw this info from Mike, and as I wrote BK something on the lines of: Too bad your products have this inconsistency, but I'm glad I got the proper explanation over a friend .... they just replied: Eh, that's called product specification, sorry
