Smoke setup on DX8

       Remove this ad - become a site supporter!
Hey guys, im trying to set up a mix on my DX8 to slave my smoke pump to my throttle that I can turn on and off with my gear switch. I tried a few different things in the mix but I can't seem to get any kind of smoke out of it. I checked the plumbing and everything seems correct. Does anyone have any ideas how to set this up

Thanks a bunch

Re: Smoke setup on DX8

This is what I had to get the aux channel to run off the gear switch. I have never run a smoke setup so I am not sure if this is right. Do you need a on/off state for smoke or is it related to the throttle? I have not found a way to have a spare channel come full on when the throttle hits a certain point. Is it possible you may need to reverse the servo setting on the smoke channel? I am still learning the more advanced stuff on this radio so if this help great if not maybe someone who knows what the hell they are doing can help.

Re: Smoke setup on DX8

Is your smoke pump programmable to throttle? I am using a Sullivan Sky Writer off my "Gear RX port and switch" through this I can turn my smoke pump off and on as well as program the pump volume related to Throttle. This is a feature of the Sullivan Pump and I chose to use the gear switch as it is on my left and I don't have to worry about Aileron or Elevator distraction during flight.

Re: Smoke setup on DX8

yes it is, I did figure it out, I slaved my pump to my throttle. created a mix with the gear switch slaved to the throttle. had to set my low value to -43% to get the pump to turn off and im still playing with my high end to get max smoke with minumum loss of oil but currently im around +60%. the key was there is a offset value at the bottom of the mix screen, I set that to 100% and it worked.......oh and also switching my lines so that the oil was pumping into the muffler and not try to go back to the tank sometimes the diagrams can't be taken too literally lol

happy to report im filling the skies with plenty of white smoke

thanks guys, hope this helps anyone else who runs into this problem
