Have a quick question. Since I am a newbie, been flying RC Jets for 30 or so years with a few fun fly airplanes thrown in. I just got into the quadcopter craze.. I have a NAZA but my ESC does not have a guide to help me orientate the correct polarity to plug in my ESCs. My question is (after I set the ESCs I have removed the Red Wire from all except one) does the ground (black in some and dark brown in other harnesses) go up to the top of the NAZA? I sure do not want to burn this puppy... Thanks
