Hi building my first real quad pretty soon with everything from banggood ,I have a turnigy 9x with the hobbyking rx,the board I got is the copter control for 18$ , whats making me feel confused is ive read abit about the cable that connects to the rx and one vid I seen on youtube a guy said that the colour coding was wrong for the servo wire that gives power to the rx can someone please set me straight on this one cheers
