Introduction

Congratulations on your purchase of the newest
and one of the most technically advanced 2-stroke
model airplane engines in the world. Whether
you are new to the sport of model aviation or an
experienced flier, you will enjoy the features of the
new Evolution® Engines Control Line (CL) Engine.

The Evolution .60NX CL Engine is designed to be
the most powerful yet controllable in its class,
extremely easy to start and operate, and provide
years of enjoyable service. It incorporates many
purpose built design features optimized for its use
in the precision aerobatics arena; unique porting
on cylinder liner for stunt, unique crankcase
to support the porting in the liner, optimized
combustion chamber design and a relocated needle

valve assembly to fit most everyone’s current
installations. Add to that the extreme lightweight
of this powerhouse and it is a winner from the word
go. Every feature is designed to ensure success
with your new engine.

This user’s guide is intended to provide the basic
information to operate and maintain your Evolution
CL Engine.

Important: While the Evolution engine is extremely
easy to operate, if this is your first experience flying
a model airplane, it is highly recommended that
you have the help of an experienced modeler during
the first few flights. Your local hobby store or flying
club can put you in touch with an experienced pilot
in your area.

Mounting the Engine

Securely tighten all engine mounting screws and re-check tightness
before each flying session.

All model airplanes include an engine mount of some
type. It is extremely important that the engine be securely
mounted to the airplane’s engine mount. Follow the
instructions included with the airplane for mounting
the engine.

WARNING: Before each flying session, check
that all engine mounting screws are securely
tightened.

Installing the Muffler

Using the included muffler mounting screws and lock
washers, attach your choice muffler with the included
hex wrench. Be sure the lock washers are placed over the
screws and that one gasket is placed between the muffler
and the engine. A second gasket is included as a spare.
Securely tighten both screws with moderate torque. The
exhaust outlet of the muffler can be rotated to allow the
exhaust outlet to be repositioned for various applications.

Failure to do so could result in product malfunction,
damage and injury.

WARNING: This product can become extremely
hot when in use, which could lead to burns.

NOTICE: Only use this product with parts specified in the
product literature.

Note: After five runs, retighten the muffler mounting
screws. Heat and vibration from these first few runs can
cause the gasket to compress. Once the muffler screws
are retightened, they will remain tight and leak-free until
the muffler is removed. Also, if you have chosen the tube­style muffler, tighten the muffler thru-bolt at this time
as well—loosen the lock nut on the back of the muffler,
tighten the thru-bolt via the screwhead at the front of the
muffler then retighten the lock nut at the rear.

EVO Team Tip:

One of the many causes of a muffler loosening is
the paper gasket material becoming crushed by

The muffler mounting accessory package includes mounting screws
(2), lock washers (2), muffler gaskets (2) and an L- wrench.

the muffler mounting to the engine.This leads to
the screws actually loosening on their own. The
surfaces, engine crankcase mount and muffler
mounting face, are machined surfaces, so there
should be little, if any, leaks between these two
surfaces. We suggest mounting the muffler without
the included gasket.

1. Loosen the lock nut on the back of the muffler and then
loosen the assembly screw.

2. Rotate the rear half of the muffler to the desired
position.

3. Tighten the assembly screw first and then tighten the
lock nut.

WARNING: Read and follow all instructions and
precautions before use.

Attaching the Propeller and Spinner

Securely tighten the prop nut using an adjustable wrench.

Attaching the Fuel Lines

Using medium silicone fuel tubing, attach the fuel tank’s
clunk line to the fuel nipple. This line will supply fuel to
the engine. Attach the vent line to the muffler pressure

Glow Plug

The Evolution engine comes with a specially designed
“Super Plug”. The plug’s unique shape directs incoming
fuel/air mixture away from the plug element. When
replacing the plug, be sure to replace it with another
Evolution 2–4 stroke Super Plug (EVOGP1).

Starting the Engine

Step 1. Fill the tank with the above-mentioned 5 or

10% fuel.

Step 2. Reattach the fuel lines, making sure the vent

and clunk line are attached to the fuel nipple
and the muffler pressure nipple.

CAUTION: Do not attach the glow driver yet.

Step 3. Place your thumb over the venturi and flip the

prop counterclockwise through 6–10 complete
revolutions, thus priming the engine. Have a
helper hold your airplane.

Step 4. Attach the glow driver.
Step 5. Turn the engine over using an electric starter.

The engine should fire within seconds of applying
the starter.

Step 6. Remove the glow driver.
Step 7. Allow the engine to run for 30 seconds. And then

adjust the needle valve for your desired ground rpm. We
suggest you set the needle valve so the engine is running
at a fast 4-cycle, if you are using the engine for stunt and
sport applications.

nipple. This line pressurizes the fuel tank with the muffler
pressure, creating consistent fuel flow, regardless of the
airplane’s attitude.

Starting the Evolution Engine

Fuel

The Evolution engine comes baseline adjusted from the
factory. We recommend using high-quality Cool Power
Omega or Power Master fuels containing 5 to 10% Nitro.
The Evolution engine has been test run using these fuels.
If another brand of fuel is used, it may be necessary to
slightly adjust the needle valve to compensate for the
differences in fuel.

Note: We have found that the best rpm to start with for
this engine is to set the needle so the ground rpm is
8200–8500. This will provide a solid 4-stroking style
run with a 2–4 break when needed. Pick the appropriate
prop to match the application and airplane. A 5–6 pitch
prop at these rpms will yield a 5.2–5.4 second lap time
on 65- to 67-foot lines. We recommend as a starting
point the mid-sized venturi .181 in (4.6mm) and a
12 x 6 to 13 x 4.5 two-blade propeller.

Why would fuel go “bad”?

The largest portion of the fuel is methanol (alcohol).
Methanol is hygroscopic; it attracts moisture. This can
cause your fuel to be contaminated with water, which will
cause poor engine performance. Additionally, the UV rays
in sunlight will eventually break down the nitromethane if
the fuel jug is stored in sunlight for long periods of time.

How can you tell when your fuel has gone “bad”?

The first indications will generally be the inability to start
the engines at previously run needle-valve settings.
Another clue might be that the engine has very poor idle,
runs but bogs down tremendously during run up and/or
will not attain the same rpms you are used to.

How do I keep my fuel fresh?

If you have the opportunity, look for someone at a flying
field on a sunny day who has a jug of fuel that is only
1/4 full. What you may notice is that there are droplets
attached to the top and sides of the container. This is the
moisture in the air condensing inside the jug because
of the greenhouse effect of the semi-translucent plastic
jug. The only way to overcome the greenhouse effect is to
store your fuel in a metal can.

You can also combat the effects of the moisture in the air
by squeezing all the extra air from your fuel container at
the end of the day or transferring your fuel into smaller
containers as the level of the fuel is reduced in your
gallon jug. Many pilots will invest in 1/2-gallon or quart­size containers and only bring that amount of fuel to the
field on any given day. This allows their main supply of
fuel to stay at home in a controlled storage environment,
virtually ensuring problem-free fuel.

How to tell if your glow plug is bad

The glow plugs on the market today are designed
to provide good service to the user and may last a long
time or a short time, all depending on the way you choose
to operate your engine.

Physical indications that you might need to change the
glow plug are:

1. Twisted or mangled glow plug element (usually
caused by too high a compression ratio).

2. Small “bumps” are attached to the glow plug
element. This is generally most noticeable during
the break-in process. These are actually tiny pieces
of aluminum that have attached to the element and
will severely hinder the operation of the glow plug.

3. The glow plug element is no longer shiny but is dull,
almost a white powder color. (This just comes with
age and is a by-product of the catalytic reaction.
The shinier the wire, the better the catalytic reaction
can be.)

Operating indications that you need to change your
glow plug are:

1. The glow element will not light with a charged glow
igniter. This indicates there is a physical short or
breakage in the element wire itself.

2. Glow plug lights but the engine will not continue
running once the battery is disconnected. (This is
usually an indication of the microscopic particles
we discussed earlier.)

3. Glow plug lights, engine runs but there is a
perceptible loss of rpm at full throttle when the
battery is disconnected. This is a typical indication
that the white powder residue is building to the
point that the catalytic reaction of the glow plug is
no longer anywhere close to being optimum.
