kicked up into the propeller, damaging it.
ELECTRICAL SYSTEM
The aircraft is not equipped with an electrical system.
Engine starting is by use of the “Pull-type” recoil starter. The low oil warning system, radio,
GPS and intercom all have their own independent battery packs.
FUEL SYSTEM
The Ascender III-C fuel system is completely independent of the other aircraft systems.
Fuel is supplied from two independent fuselage-mounted tanks located beneath the engine. Each
tank holds 4.5 US gallons (17 litres) useable fuel or 27 lbs for a total of 9 US Gallons (34 litres)
or 54 lbs useable.
Fuel is fed to the engine by the crankcase-pulse powered Minuki diaphragm fuel pump mounted
on the right side of the engine mount plate.
Fuel quantity is registered by observing the fuel level in the translucent tanks. Calibration
markings are provided on the rear of the right tank in litres.

Correct fuel indication is only provided with
the aircraft in a level ground attitude.
There is no fuel shut-off valve. Fuel filtration is provided by an in line Bosch fuel filter and two
pick-up fuel filters inside the individual fuel tanks. There are no provisions for fuel draining
other than by pumping out or removing the tanks.
The fuel tanks are vented by independent fuel cap vents.
An engine plunger-type fuel primer is located on the fuel line behind the pilot’s seat to facilitate
starting.
HEATING AND VENTILATION
There are no provisions for cockpit heating and therefore flying clothing appropriate to the
season and altitude is imperative. Flying in temperatures below 10
0
C is not recommended.
