The gas or fuel tank is typically placed with the tank’s center located over the aircraft’s Center of

Gravity (C/G) point, thus assisting in lessening the effect on the aircraft’s pitch-moment as fuel is

consumed from the tank. DLA engines have a “diaphragm-type” pump in the carburetor and thus

the relative level of the tank’s, fuel exit point to the carburetor’s in-take point is not critical.

However, keeping these two points at the same level can be desirable. The tank and tank

“stopper” material must be compatible with gasoline. (Silicon tubing is NOT suitable for gasoline

use.)

The gas line or “hose” material must be Tygon® or a similar material that is completely

compatible with gasoline and the type of oil used. It is recommended that the gas line shown in

the “ACCESSORIES” section of this manual be used. This gas line is available from Golden Skies

R/C Aircraft, Inc. The gas or fuel lines inside diameter (ID) should be at least as big as the

carburetor’s inlet nozzle diameter. The tank is shown to be semitransparent so one may see the

plumbing inside the tank. The vent line is located on the outside-top of the tank and vents to the

bottom of the aircraft.

The preferred fuel tank, gas line plumbing, and Fuel Point connections are shown in the following

diagram. (See GS R/C Website for additional pictures) www.goldenskiesrc.com The In-Line and

128cc QUAD dual carburetors may be supplied with gas by any of the following methods:

1. Single tank with one clunk & line and a “Tee” splitter to each carburetor, 1/8” ID line

2. Single tank with dual clunks and lines, one to each carburetor, 3/32” or 1/8” ID lines

3. Dual tanks, each with a single clunk/line to each of the two carburetors, 3/32” or 1/8”

ID lines
