This is an example of the stacked fuel tank system with the plumbing illustrated by RCKen.

There is an eight ounce in the nose and two 24 ouncers on top of the fuselage for a total of 56 ounces and almost two hours endurance. This tank system with three tanks provide an effective way to carry a lot of fuel without the sloshing and subsiquient unporting of the clunks if a single large tank were used and surprisingly still maintains CG at least within reasonable limits however it is neccessary to continually retrim throughout the flight first up then down. The airplane is a Bridi Sun Fli 111 with an OS 70 surpass.
