carve or cut a prop near the hub for any reason (such as
to fit a spinner).
A 3" CGP 4-Pin Snap-On Spinner is available for the Tiger
120 ARF. It is a rugged precision molded spinner that
does not require any special mounting nuts or screws.
Carefully read the spinner instructions and warnings
included in this book. Although a spinner helps reduce
the chance of injury from a rotating prop, extreme caution
always must be used when the engine is running.
As with other precision equipment, a new engine should
be "broken-in" to enhance performance and extend its
life. Breaking-in usually consists of running the engine
with a "rich" fuel mixture and at lower RPMs until all the
moving parts get to "know each other better." This can be
done with the engine mounted in the model or securely
clamped into a CGP Engine Test Stand or similar device.
Refer to your engine's operating manual for the recom-
mended break-in procedure and follow it carefully.
STARTING BATTERY AND GLO-PLUG CLIP: A 1-1/2
volt battery is required to heat your engine's glo-plug for
starting. Wires connect the glo-plug clip to the battery.
Because engine starting draws a lot of electric power
from the battery, rechargeable ni-cad batteries are rec-
ommended. Although they cost more initially, they are
more economical in the long run than frequently replac-
ing dry-cell batteries.
FUEL: For best engine performance, use the fuel rec-
ommended by your engine's manufacturer. 2 and 4-
cycle engines require different fuel blends. Ask your
dealer to recommend a good quality fuel.
FUEL PUMP: Needed to transfer fuel from the fuel can
to the model's fuel tank. A simple squeeze-type bulb will
do for small tanks, whereas manual crank or electric
pumps fill larger tanks more quickly.
FUEL LINE: Have about 3 feet of silicone fuel line to
make connections between the fuel pump, the fuel can,
and the model's fuel tank.
EXTRA PROPS: Experts always have a few spares on
hand, so flying doesn't have to stop due to a broken pro-
peller.

FIELD EQUIPMENT
The following equipment will be needed at the flying field
to start your engine, make adjustments, and clean your
model after flying.
FLIGHT BOX: Something sturdy in which to carry your
equipment. CGP's quick-building MiniTote carries the
basics: fuel, starter and battery, and a few essential tools.
The larger CGP Super Tote is economical, easy to build,
and pack lots of utility into little space. They hold fuel,
transmitter, starter & battery, as well as many tools, in a
balanced load that is easy to carry. The fuel tote is
designed to carry your fuel in a handy box that keeps the
jugs from rolling around in your car.
