Secondary Grouping:

Assembly:

Final assembly of the sub-components listed below.

Tank:

The location the fuel tank has not yet been finalized.

The fuel should be centered on the rotors, therefore;

Could the front of the two booms contain tanks, Possibly for gravity feed.
Can a third and larger tank be located partially beneath the engine and possible at a low elevation on through to the below part of the seat.

This should allow for a roughly 24" wide by 6" deep by 18" high (1.5 sq-ft) 'baggage' compartment directly behind the seat.

It would appear that on larger helicopters the fuel tank can only be filled to 70% of its total capacity. This is done for crash worthiness.

And more:

Consider locating a small upper tank in the booms or around the mid transmission. This tank(s) will provide gravity feed to the carburetor. A fuel pump will provide fuel from the main tank, located at the base of the bulkhead, to the upper tank. The pump will be alarmed.

	Fuel Pump(s):

	Shutoff Valve(s):
	Quick Drain:
	Vent:
	Lines:

3/8" OD fuel lines?..

Gascolator:

Strainer or gascolator must be located at lowest part of system. This will probably be at the base of the firewall (bulkhead) on the engine side.

Notes:

If the helicopter were to be made aerobatic, then there must be the ability to draw fuel from the tank in all orrentations.
