I built my own system. I had an old fuel that was not working for one of my smaller turbines and it will pump as much as 15 oz. a min at 7 volts so a 24 oz. tank will last less than a couple of minutes. I also have a second receiver that runs the system to avoid glitz interference on the main Rx system. I have the pump set up on a slider switch on my transmitter to vary the voltage so it will pump as slow as a couple oz. a minute which gives a light density smoke. A few clicks more and I can get a medium density smoke and of course at full voltage, it makes a lot of smoke. I am running dual stainless steel tubes from Tam with this set up on my Big Boomer. Most of my flights last 6 to 9 min and I have smoke on at least half the flight. I have been using SuperDri but I just bought a 5 gal. can of Freedom Form Release Oil to try. As you can see it puts out lots of smoke.
