RE: Sullivan Skywriter Smoke Pump Questions
I always like to put a mix in on the throtle, as well as have just an on switch. The mix is for flying and the on switch is for getting the pump primed. You will notice a LOT of fluid on the tail of the plane if you are running tooo much smoke fluid. I like to max out the smoke effect, then reduce it a bit to help keep the mess off of the plane. MOST important is HEAT!! If you don't have enough, you won't get the desired effect. Some people use a heat coil to help get the fluid hotter before it goes into the muffler or pipe. For 30cc, you may even need to add a restrictor in the line to keep the fluid low enough to burn, and the pump running enough to pump. Hope this helps.
