I am new to the forum and need to trouble shoot the setting up of Seaplane Widgeon. I bought this plane a while back and was setting up over the weekend. All the connections went well, except, only one of the motors is working and the other motor has started beeping, but does not work when I give throttle. Just some reference... the wires from the two motors and their esc is coming together (as per design) and I added it to the throttle slot in the AR620 receiver. Does the motor + ESC need some kind of calibration? whats the best way to trouble shoot this? Appreciate the help !
