First things first. This is not really a software development kind of question. You really should have posted this in another thread. Shields, boards and sensors comes to mind for some reason, I don't know, maybe because this question is about a board? Or even better, Getting Started - MultiWii config and setup
viewforum.php?f=18 The forum is setup so that you can post questions in an appropriate thread where others will more likely help you than if a question off topic (like this one) is posted in the wrong place. Or am I being too captain obvious with this?

I have no idea what you mean by links and threads when it comes to a FC

If you supply it with 5v DC and the FC LEDs light up it is still working. To arm it involves setting the FC and the TX up correctly (see links below)

If you fried a receiver somehow by hooking it up to this FC, it is most likely not the FC's fault, but instead, you most likely had some wires on wrong. Now that you have probably supplied reverse polarity or the wrong voltage or whatever fried your RX, there is a chance your FC may be toast too.
