Mounting the Engine

Most model airplane designs make provision for an engine mount. It
is extremely important that the engine mount be securely attached
to the airplane's firewall and that the engine is securely attached to
the engine mount. Follow the instructions included with the airplane
for mounting the engine. The engine should be fastened in place
with 4 bolts, blind nuts and lock washers. Use 1/4" or 6mm bolts.
If you decided to fasten the engine using a flexible motor mount,
always choose parts with enough solidity and strength. Make sure
all bolts are tightened and regularly check that they remain tight
and in good condition.
note: The use of threadlock on all engine mounting fasteners is highly
recommended.
Important: Air is necessary to cool the engine during operation. Make
sure that sufficient air circulation through the cowling is provided. As
a basic reference, the outlet area should be 3–5 times the area of the
inlet area to provide adequate cooling.

Throttle Linkage

Carefully attach the throttle linkage to the engine. We recommend
the use of a ball link on the carburetor. Make sure that the linkage is
free to operate from low throttle to high throttle and confirm that the
low throttle setting on the transmitter closes the carburetor butterfly
to the low idle position. Adjust the length of the pushrod until full
5
throttle opens the carburetor butterfly fully, while low throttle, low
trim completely closes the butterfly.

Attaching the Fuel Lines

Use large gasoline-compatible fuel line in the fuel tank as well as
the supply line to the engine. The fuel stopper and the fuel lines
used in the fuel tank must be compatible with gasoline.

Fuel for the Evolution Gas Engine

The Evolution gas engine has been designed to run on a mixture of
high-quality 91 octane unleaded gasoline and synthetic oil intended
for racing 2-stroke gasoline engines. For the break-in period of the
new engine, mix the fuel in a ratio of 30 parts gasoline to 1 part
lubricant. After break in, use a ratio of 40 parts gasoline to 1 part
lubricant.

Spark Plug

The Evolution 80GX engine uses a CM-6 type of spark plug. Before
installing the spark plug you will need to set the spark plug gap to
the following dimension: .024 in to .028 in (.6mm to .7mm)

Selecting a Suitable Propeller

The Evolution 80GX has been designed to generate maximum power
at 6200–6600 rpm, according to the type of exhaust used. If you
wish to utilize the maximum power output, choose a propeller which
will allow the engine to reach these revolutions, or slightly lower
revolutions. (The engine will unload in the air, depending on the
aircraft speed and propeller selected.)
We do not recommend using propellers that allow the engine to
reach more than 7500 rpm on the ground.

Suggested Propeller Dimensions

The 80GX engine is designed for optimum performance and torque
when operated between 6200–6600 rpm. Choose your propeller
according to the chart and to achieve approximately 6400 rpm on
the ground for best performance and the lowest noise signature.
