User Manual

NEVER disassemble the fuel pump or pressure regulator.
Their original performance may not be restored after
reassembly.
DO NOT obstruct the small rectangular hole in the side of
the regulator cover.
DO NOT allow foreign matter to enter the fuel system. Dirt
inside the pump or regulator, no matter how small, may
obstruct the flow of fuel and prevent these components from
working properly.
NEVER insert anything into the inlet or outlet nipples in an
attempt to clear a suspected obstruction. (See CARE &
MAINTENANCE section at the back of this booklet.)
ALWAYS use fuel filters. Keep the fuel tank scrupulously
clean and filter all fuel as it enters the tank (e.g.via an
O.S.'Super-Filter' Code No.72403050) and use a good
quality in-line filter between the tank and pump. Remember
to inspect filter screens at regular intervals and rinse clean
as necessary.
NEVER use gasoline, kerosene, diesel fuel or other
petroleum products for cleaning the pump, regulator or fuel
lines. Silicone-rubber parts will be ruined by these materials.
Use only alcohol (methanol) or glow fuel for cleansing these
items.
The choice of propeller depends on the design and weight of
the aircraft and on the type of flying in which you will be
engaged. Determine the best size and type after practical
experimentation.
As a starting point, refer to the props listed in the
accompanying table.
Slightly larger, or even slightly smaller, props than those shown
in the table may be used, but remember that propeller noise will
increase if blade tip velocity is raised, due to higher revolutions
or a larger-diameter / smaller-pitch prop.

Make sure that the propeller is well balanced. An
unbalanced propeller and / or spinner can cause serious
vibration which may weaken parts of the airframe or
affect the safety of the radio-control system.
DO NOT forget the WARNINGS and NOTES on propeller
and spinner safety given on pages 2,3 and 4.
