SILENCER

Installation for FS-30S and FS-40S
Screw the exhaust header pipe into the exhaust port
until it "bottoms", then unscrew it just sufficiently to
achieve the required exhaust outlet angle. Secure the
pipe in this position by tightening the locknut firmly
against the cylinder head with the wrench supplied.
Then, screw the silencer onto the end of the header
pipe and tighten locknut firmly. Re-check tightness of
locknuts when engine is hot.

LINKAGE OF THROTTLE LEVER

First, ensure that the throttle rotor is fully closed when
the throttle-lever is in the closed position. Adjust rotor
stop screw if necessary. Then couple the lever to the
throttle-servo so that the rotor is fully closed when the
transmitter throttle stick and trim lever are in the fully
retarded position.
If a 2-volt cell is employed,
use a resistance wire, as
shown, to reduce applied
voltage, otherwise element
will overheat and burn out.
1.5 volt heavy-duty or 2 volt rechargeable
dry battery lead-acid cell (at least 5Ah)
Warning (Very hot)
Never touch the nichrome wire while the battery is
connected.
Resistance coil
(nichrome wire)
Battery leads
Adjust applied voltage by changing the position of clip on
resistance coil until glowplug element is glowing bright red.

BEFORE STARTING

Tools, accessories, etc.
The following items are necessary for operating the
engine.
1 Fuel
Model glowplug engine fuel of good quality, preferably
containing a small percentage of nitromethane. (See
"Advice on selection of fuel, glowplug and propeller")
2 Glowplug
O.S. Type F glowplug is installed in the engine.
3 Propeller
Suggested propellers are shown in the ADVICE ON
SELECTION OF FUEL & PROPELLER section.
4 Glowplug battery
The power source for heating the glowplug may be a
1.2volt Ni-cd battery a large heavy-duty 1.5volt dry
cell, or a 2-volt rechargeable lead-acid cell
(accumulator).
10
5 Plug wrench
Used for tightening glowplug.
The O.S. long plug wrench is available
as an optional accessory.
6 Battery leads
These are used to conduct current from the battery to
the glowplug. Basically, two leads, with clips, are
required, but, for greater conve-
nience, twin leads with special
glowplug connectors, as shown on
the right, are commercially available.
7 Fuel tank
For installation in the model, a 150cc(5oz.) for
FS-30S and FS-40S tank is suggested.
These will allow 10 minute flight.
8 Fuel bottle or pump
For filling the fuel tank, a simple,
polyethylene "squeeze" bottle, with a
suitable spout,is all that is required.
Alternatively, one of the purpose-made
manual or electric fuel pumps may be
used to transfer fuel directly from your
fuel container to the fuel tank.
