Hi Mike. I am trying to assign a switch to power up the smoke pump on a new Yak I am putting together. I am running the SD10G transmitter and reciever into a Power Expander Sport. I have channel #5 open on the reciever and the Expander. The smoke pump is a slimline unit with a power cord to the battery and a tie into the throttle servo with a Y harness to modulate the quantity of smoke being pumped. The smoke pump is rated to pull 240mah when running. My question is how to get the channel assigned to the gear switch so I can power the pump on and off using the gear switch to do it.
