I used three lines so one is dedicated to filling the tank, and I have two pickup lines with clunks, and one that vents out on the bottom of the model. For the smoke tank I used a Du-Bro ( ) tank equipped with a gasoline stopper. If the tanks are forward or aft of the center of gravity, the balance of the airplane will change during the flight. Mounted directly over the center of gravity, no noticeable trim changes occur as the fluid is used up. I use a 32-ounce fuel tank and a 24-ounce smoke tank, for a total of 56 fluid ounces added to the aircraft ready for flight. It is important to center the tank on the aircraft’s center of gravity. Shown from the inside of the composite fuselage are the fuel and smoke lines used to fill each tank. Slots in the new tray allow Velcro straps to secure both tanks. So I made a 1/8-inch lite-ply floor and glued it over the existing tray using Zap 30-minute epoxy ( ). The original tank tray on the Composite QQ Yak 54 is designed for only the fuel tank and is mounted directly above the wing tube. The first order of business is to mount the smoke tank. It is a good idea to use a larger than normal radio battery pack if you are going to use lots of smoke-on time. Smoke pumps can draw as much as 1 amp of current and, on average, will use about 17mAh per minute.
The TME SmartSmoker Pro ( ), can be powered by a spare receiver channel. Depending on the pump used, a battery to supply power to the pump may be required. The TME SmartSmoker Pro controller can be powered either from the receiver port or by a separate battery pack.Ī smoke system includes the smoke pump, gasoline-grade and neoprene fuel line, a smoke oil tank, fuel fittings, and a smoke muffler.
