Hi Julian, unless they have changed one ESC lead had Power from it the other 3 didnt, I like you read somewhere that no power was to come from any ESC and I was wondering why they would supply 1 only with power, very poor communication on there behalf, anyway we learn as we go.John.
Actually I am the guy (idiot) who recommended to Julian to remove the red wire from the plug and turn it back, and checking the quick start guide dated 22 Oct 2012, on page 2, ZeroUAV do say that if you are using a Gimbal, you will need power from one of the ESC's so they suggest that you can leave any one of the red wires connected. Anyway, as you say we are learning as we go along.
Personally, I would rather use power from a separate UBEC to drive the gimbal.
Cheers
Rob
