ENGINE & PROPELLER
Your plane flies well using any 2-cycle engine size from .35
to .45. (We do not recommend a 4-cycle engine for this
aircraft, due to the more complicated set-up required.) The
numbers .35 to .45 refer to the amount of space the piston
moves through inside the cylinder of the engine. This
space is called displacement; larger displacement general-
ly means more power. If you live in a hot climate, or your
flying field is approximately 3,000 feet or more above sea
level, you should stay with a .45 engine. It's a good idea to
select an engine that is popular at the flying field, so that if
you have any engine problems, other modelers will be
familiar with the engine and be able to help.
The propeller size must be matched to the engine. For
example, a .35 may use a 9" diameter prop while a .45 can
use a 10" prop. Refer to the information that is supplied
with your engine for recommended propeller sizes. It's
wise to buy a few spare props, as everyone breaks them
occasionally, and particularly often when learning to fly.
Balancing your propeller helps to protect your radio from
the damaging effects of vibration. There are good, easy to
use prop balancers on the market. Follow the instructions
that are supplied with the prop balancer. Never carve or cut
a prop near the hub for any reason (such as to fit a spin-
ner).
A 2-1/4" CGP 4-Pin Snap-On Spinner is included
in the Eagle 2 ARF. It is a rugged precision molded spin-
ner that does not require any special mounting nuts or
screws. Carefully read the spinner instructions and warn-
ings 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.
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 SuperTote or Monster Tote are both eco-
nomical, 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.
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 recommend-
ed. Although they cost more initially, they are more eco-
nomical in the long run than frequently replacing dry-cell
batteries.
FUEL: For best engine performance, use the fuel
recommended by your engine's manufacturer. 2 and 4-
cycle engines require different fuel blends. Ask your deal-
er to recommend a good quality 5-10% Nitro 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 propeller.
