Here's how the timer tank worked: Fire up the bad boy, set needle, just prior to launching your plane, you'd move the wire spring (held in place by small groove) another sping around the top of tube, inside the tank (see photos) would push the tube down sealing the top half of tank off, the bottom would be full and you'd have a premeasured, predictable run time.
