So many possibilities to troubleshoot... Where do I begin?

Here is my idea. I'm building a hexacopter. I'd like my LED controller to take telemetry data from the flight controller and change the colors based on information from the flight controller.

Caltoa:
Or do you want to control 8 led strips ?

Actually 7 (one strip per leg. to help me see the orientation easier and a "heartbeat" LED) All of them RGB

For my application size and weight will matter a little. I'll look around a bit to see if I can get a mosfet small enough to fit on my 55mm square board.

Also based on the attached drawing (that I revised) did I take care of Crossroads suggestions?

I can't thank you all enough for the tremendous help!
