I have just built a u580 as a start to some very basic aerial photography. I have it set up with DJI Naza V2 and all set up and fly’s. So I want to get the retracts to work but plugging them into X1 on Naza as per this is channel 5 on a toggle switch on my transmitter. All channels are working visually via Assistant software but when using normally the landing gear does not work?? Do I need to activate its output form Naza or something? As if i plug to F1 and switch on gimbal when i tilt it they retract - so servos do work just no feed from X1?
