My Big Boomer carries 24 oz and I built my own smoke system using an old turbine pump. My system uses an ESC to control the flow of smoke using a slider switch on the TX. A couple of clicks on the slider and I can have smoke the whole flight which is 8 min or I can go max flow on the slider switch and it will pump 8 oz a min so the tank will only last less than 3 min. The first couple of photos is light, the rest are heavy.
