Must have a means to automatically supply a fuel for a short duration to one engine only should the main fuel than run dry.

Secondary Grouping:

Assembly:

Final assembly of the sub-components listed below.

Tank:

Location high behind the pilot's head. It will be attached to the bulkhead. This will result in gravity feed.

There could be an option of tank sizes, to be used for various codes or applications.

The tank(s) might have a handle and be removable. This way they could be carried to the location of fueling.

The intent is to attach the power train to both of the top outer corners of the bulkhead (plus a lower central mount). The bulkhead then serves the 3 functions of seat, tank and structural. There could be a simple sight gauge built into the seat.

Other possible locations are:

Under the seat. It could possibly help with impact absorption on a very hard landing. Only if the fuel can be discharges first.

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. If the SyncroLite is to have a high fuel tank then the aerodynamic profile of the tank will cause its fuel exit port to have a lower elevation and this could be detrimental to gravity feed.

Larger Tank:

For crash worthiness, the fuel tank should only be filled to 70% of its total capacity. This means that the tank size should be 7.14 gallons and the filler should be below the top.

	Additional Fuel:	See DESIGN: Fuselage - Body [B216]. Cannot be accessed in flight.
	Fuel Pump(s):
	Gascolator:
	Shutoff Valve(s):
	Quick Drain:
	Vent:	I can also attest to the positive benefit of Ralph Taggart's suggestion to route the opening of the vent below the bottom of the tank. I didn't loose a drop of fuel while my gyro was upside down. Since the vent line is secured to the airframe (to keep it out of the prop), it features a valved quick disconnect in order to remove the fuel tank.
