The motors that I am using won't spin or arm when connected to my Naza M Lite. However, I can get each motor spin individually when I connect them directly to the receiver. I am pretty certain that the ESCs are plugged into the flight controller correctly along with the wires connecting the flight controller and receiver. On occasion, the motors will twitch back and forth as well as beep when connected to the flight controller, but that happens without me doing anything. The Naza assistant software picks up the movements on my controller. Below is a video showing my problem.
Aileron goes to Ch1
Elevon goes Ch2
Throttle goes to Ch3
Rudder goes to Ch4
U goes Ch5
