Tools, accessories, etc. The following items
are necessary for operating the engine.
BEFORE STARTING
The choice of propeller depends on the design
and weight of the aircraft and 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,
Propellers
Type
props than those shown in the table may be
used, but remember that the propeller noise
will increase, due to higher rpm or if a larger-
diameter/lower-pitched prop is used. Never touch, or allow any object to come into
contact with, the rotating propeller and do not
crouch over the engine when it is running.
Reminder!
Warning:
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-controlled system.
DO NOT forget the WARNINGS and NOTES
on propeller and spinner safety given on
front pages.

Since the FS -110-P is intended
to be started with an electric
starter, the addition of a spinner
assembly for centering the starter sleeve is
desirable. Use a heavy-duty, well balanced
spinner either of metal or plastic.

FUEL
The FS -110-P should be operated on a methanol
based fuel containing not less than 18% (volumetric)
castor oil, or a top quality synthetic lubricant (or a
mixture of both), plus a small percentage (5-20%) of
nitromethane for improved flexibility and power. Some
commercial fuels also contain coloring additives as an
aid to fuel level visibility. In some cases, these additives
have indicated slightly negative effects on the
performance. We would suggest that you use such fuels
only if you are satisfied that they do not adversely affect
running qualities when compared with familiar standard
fuels.
Model engine fuel is poisonous. Do not
allow it to come into contact with the eyes or
mouth. Always store it in a clearly marked
container and out of the reach of children.
Model engine fuel is also highly flammable.
Keep it away from open flame, excessive
heat, sources of sparks, or anything else
which might ignite it. Do not smoke, or allow
anyone else to smoke, near to it.
Reminder!
When changing to a fuel brand or
formula that is different from the one to
which you are accustomed, it is a wise
precaution to temporarily revert to in-
flight running-in procedures, until you are
sure that the engine is running entirely
satisfactorily.
