Hi I just got a cooling fan for my mini e-revo esc that I planned on using with my DX3s in the AUX channel on the SR3300T receiver. I thought I would be able to turn it on and off with the AUX switch. Is this possible?
It won't work. You're just using the 2 common lines for the power to the fans (+ and -) you would have to incorporate the signal side of the rxr to activate your fans, but since its a pulse signal you would need a relay to make it work.
