Here goes - I have Tam's smoke system (Motor) connected to aux 4 on the receiver and want to use the aux 2 switch on the transmitter to turn it on and off. The aux 4 switch is a rotary and it turns the motor on proportionaly to the switch position. I do not have any flight modes programed in and the P120 is single channel on the throttle so the aux 2 switch does nothing.
I've wasted a lot of time on this so am asking for help.
Thanks,
Galen

I am by no means an expert but I have accomplished this by mixing the two channels using a free mixer, enabling the mix on the Aux 2 switch (page through the options on the mixer page to get to the switch enable/disable screen), then use Code 17 to disable the Aux 4 switch.

There is probably a better/easier way, hopefully one of the real experts will chime in. But this should get you going for now.

I'd do it just like barry suggested..... I’m no expert but the use of a free mix is simple and straightforward and will work..... Important to go to function 17 and make sure Aux 4 is de-activated.

Thanks guys, I thought that's what I was doing but evidently I wasn't. Anyway, It works fine now.
Thanks again.
