Safety Warnings

Model engines produce a substantial amount of power, which can create unsafe situations if not
used correctly. Always use common sense and observe all safety precautions when operating,
handling or performing any procedure involving your engine. Failure to follow safety precautions
could result in serious injury and property damage.

• Always ensure spectators, especially children, are at least 30 feet away when running
the engine.

• Always ensure that the propeller is securely attached to the engine shaft and all retaining

fasteners are tightened properly before EACH flight. Use of blue threadlock to tighten nuts
is advisable.

• Always keep small parts out of the reach of children as they can be choking hazards.

• Always secure the airplane before powering the engine.

• Always keep your face and body away from the path of the propeller blades when starting

or running your engine.

• Always stand behind the propeller when making carburetor adjustments.

• Always wear safety glasses or goggles when starting and running your engine.

• Always keep your fuel in a safe place away from sparks, heat or anything that can ignite.

• Always ensure the aircraft is secure and will not move once the engine is started.

• Always rebind your transmitter to your receiver(s) after setup and before rst ight.

2

• Always ensure the throttle failsafe is set to low throttle in your transmitter.

• Always perform a range check prior to ight.

• Always cut off the fuel supply (pinch or disconnect the fuel line to the carburetor) or use

the throttle linkage to shut off the air in order to stop the engine.

• Never use hands, ngers, or any other body part to stop the propeller.

• Never throw any object into a propeller to stop it.

• Never run the engine in the vicinity of loose small objects, such as gravel or sand, to avoid

the propeller uncontrollably throwing such materials.

• Never wear loose clothing or a loose neckstrap when operating your model engine as these

items could become entangled in the propeller.

• Never have loose objects such as screwdrivers, pencils, etc. in your pockets when operating

your model engine. These could fall into the propeller.

• Never allow fuel to come into contact with eyes or mouth. Gasoline and other fuels used
in model engines are poisonous.

• Always ensure gasoline and fuel are stored in a clearly marked container away from
the reach of children.

Precautionary Guidelines

• Always mount the engine securely on a bench mount or high-quality engine mount.

• Always use the correct size and pitch of propeller for your engine. Refer to the Propeller Chart

in this manual.

• Always conrm proper balance of your propeller prior to installation of the engine. Failure
to do so could result in damage to the engine and/or airframe.

• Always utilize an electric starter to start your engine.

• Always discard any propeller that is nicked, scratched, cracked or damaged in any way.

• Always run your model engine in a well-ventilated area. Model engines can produce possibly

harmful carbon monoxide fumes.

• Always store your fuel safely in a sealed, water-resistant container.

• Always store fuel in a cool, dry location. Do not allow fuel containers to come in direct

contact with concrete, as the fuel may absorb moisture.

• Always responsibly discard fuel if there is condensation and/or water inside the fuel
container.

• Never return unused fuel from the fuel tank back into the fuel container.

• Never attempt to repair or modify a propeller beyond its intended use.

• Never handle model engines, mufers and/or tuned pipes until they have had time to cool.

They can become extremely hot when in use.

cludes mounting screws (2), lock washers (2),
muffler gaskets (2) and L- wrenches (2).

Connecting the Throttle Linkage

1. Put a lock washer on each of the muffler
screws. Push the muffler screws through
the cylinder head.

2. Place the muffler gasket over the engine
mounting screws.

3. Align the mufer gasket with the exhaust

opening and the muffler mounting screws.

4. Tighten the muffler screws.

IMPORTANT: Tighten the muffler screws after
five tanks of fuel. The muffler screws may
loosen from heat and vibration.

It is important that you tighten the muffler
through-bolt after each use of the first three
full tank engine runs. The heat will cause ex­pansion of the through-bolt and muffler body
parts. After the third tightening, no further
muffler loosening should occur.

To tighten the muffler through-bolt:

1. Loosen the mufer lock nut.

2. Tighten the muffler through-bolt screw.

3. Tighten the mufer lock nut.

1. Use a secure method to attach the
throttle linkage to the throttle arm on the
carburetor.

2. Power on the transmitter and receiver.

3. Move the throttle stick to the middle stick

position.

4. Adjust the throttle arm so the arm is 90

degrees to the throttle pushrod.

5. Center the throttle servo. Install a servo arm
with a hole 11mm (7/16 in) from the center

of the arm.

6. Use a clevis to attach the throttle linkage to
the servo arm.

Fuel

We recommend using high-quality Cool Power, Omega, or Power Master fuels containing 10 to
15% 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 valves to compensate for the differences
in fuel.

Glow Plug

The Evolution engine comes with a specially designed “Super Plug” that prevents idle and
transition flameouts. The plug’s unique shape directs the incoming fuel/air mixture away from
the plug element. When replacing the plug, be sure to replace it with another Evolution 2- or

4-cycle Super Plug (EVOGP1).

Starting the Engine

1. Fill the tank with the above-mentioned 10
or 15% fuel.

2. Reattach the fuel lines, making sure the
vent and clunk line are attached to the fuel
nipple and the muffler pressure nipple. Do

not attach the glow driver yet.

3. The high-speed needle valve should be

turned open 2-turns from closed for the
initial first start.

4. With the throttle fully open, place your
thumb over the carburetor or the exhaust
outlet of the muffler and flip the prop
clockwise through 6 complete revolutions,
thus priming the engine.

5. Close the throttle to the idle position and

have a helper hold your airplane.

If you are planning to use a tuned exhaust
system, we highly recommend the use of
either of the following Hangar 9

HAN3015 #9 Performance Plug
HAN3020 #3 Performance Plug

®

glow plugs.

The Hangar 9 START KIT (HANSTART) includes
everything needed, except fuel and starter, to
get the Evolution engine running.

6. Attach the glow driver.

7. Turn the engine over using an electric

starter. The engine should fire within
seconds of applying the starter.

8. Allow the engine to idle for 30 seconds.
Adjust the throttle trim if necessary to
achieve a constant slow idle.

9. With the glow driver still attached and a
helper securely holding the airplane, ad­vance the throttle smoothly to full throttle.
The engine will transition to full rpm.

10. Reduce the throttle to idle and remove the

glow driver.

Setting the Needle Valves

The low-speed needle has a limiter that
prevents over-adjustment. If your engine
starts from the above procedure, but won’t
reliably continue to run with the glow driver
removed, follow the steps below.

High-Speed Needle Adjustment

With the engine running, advance the throttle
to full throttle while a helper securely holds
your airplane. Carefully pinch and release the
fuel line to temporarily restrict the fuel flow.

High-Speed Needle Adjustment
CAUTION: Do not reach over the

propeller while the engine is running.

Correct: If the high-speed needle adjustment
is correct, the engine will increase rpm slightly

(about 300 rpm) and then resume normal

operation.

Too Rich: If the engine increases a lot (1,000
rpm or greater), the high-speed needle is too

rich and must be leaned or turned clockwise.
Too Lean: If the engine doesn’t increase rpm

and simply dies, the high-speed needle is
lean and must be richened or turned counter­clockwise.

8

Low-Speed Needle Adjustment

The low-speed or idle needle valve, included
with the SetRight
at the factory for best performance at close to
sea level conditions. It may be necessary to
fine-tune the low-speed adjustment using the
following procedure:

1. Start the engine and let it warm up, prior
to attempting any adjustments. Make sure
that the high-speed adjustment process is
complete before attempting to adjust the
low-speed needle valve.

Low-Speed Needle Adjustment

The low-speed needle adjustment range is
limited, preventing adjustment beyond the
practical range.

2. Close the throttle slowly. You will adjust
the low-speed needle setting by rotating
the SetRight adjustment bar clockwise to
lean the engine and counterclockwise to
richen the engine.

CAUTION: Do not attempt to adjust
the low-speed needle valve while the

engine is running.

3. The fuel mixture should be adjusted as

follows: The low-speed fuel mixture is too
rich if, when opening the throttle rapidly,
the engine emits smoke and “stutters” or
“stumbles.” Correct this by rotating the
SetRight adjustment bar clockwise in small
increments. Continue this process until the
engine transitions smoothly from low rpm
idle to high rpm without hesitation upon
opening the throttle rapidly.

4. The low-speed fuel mixture may be too lean
if the engine stops at the lowest idle position
or it stops when the throttle is rapidly opened
from the idle position. Correct this by rotating
the SetRight adjustment bar counterclock­wise in small increments until the engine
transitions smoothly without hesitation upon
opening the throttle rapidly from idle.

assembly, is preadjusted

Low-Speed SetRight Needle Valves

The design of the SetRight needle valve
system is such that, during normal operating
conditions, the typical user will find that the
range of adjustment allowed by the system is
more than adequate for most situations. As a
matter of fact, we intended this to be used as
a tool to identify operating problems. If you
find that the range of adjustment allowed by
the SetRight needle is inadequate after your
initial period of running, then a problem in
your engine system has occurred. This might
be a bad glow plug, dirty or old fuel, an air
leak in the fuel system somewhere or any
number of other reasons. Do not make any
permanent adjustment range changes to the
SetRight needle system if it was once working
correctly for you and now does not.
Investigate other problems first.

However, occasionally due to atmospheric,
altitudinal or fuel conditions, you may find
that the range of adjustment built into the
SetRight needle valve system is inadequate
for your needs. These conditions are rare and
easy to fix.

EN

Low-Speed SetRight Needle Valve Correction

Should the low-speed SetRight needle valve
need to be adjusted outside the factory­established parameters, follow these steps:

A. Loosen the setscrew found on the ring of

the SetRight assembly to which the
adjustment bar is attached.

B. Rotate the needle valve itself (small

slot-headed screw inside the blue ring of

the SetRight assembly) clockwise to lean

the mixture or counterclockwise to richen
the mixture as desired.

C. Retighten the setscrew on the ring of the

SetRight assembly and you have
re-established a new range of motion.

Maintenance

After each flying session:

1. Fully drain the fuel from the tank.

2. Start the engine and run it until the fuel is
completely run out of the engine.

3. Try starting the engine three more times or

until it will no longer fire. This gets all the
fuel out of the engine.

Now add several drops (about 10) of after-run
oil (EVOX1001 Evolution Engine’s Blue Block
After Run Oil) into the carburetor and the

engine should turn over for a few seconds
with the starter. This will prevent rust and
corrosion.

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 indication will generally be the in­ability to start the engine 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 that 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 that is condensing inside
the jug because of the greenhouse effect in
a semi-translucent plastic jug. This will also
occur within a metal fuel can if the sun warms
the contents.

You can 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.
Many pilots will invest in 1/2 gallon or quart­size containers and only bring that amount of

9

EN

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.

Tip: Do not store plastic fuel jugs on metal or
concrete surfaces, this can also cause
moisture contamination.

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
dependent upon 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 elements

(usually caused by too high a compression
ratio).

2. Small “bumps” are attached to the glow
plug element. This will generally be 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.

Troubleshooting Guide

3. The glow plug element is no longer shiny

but is a 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 that
there is a physical short or breakage in the
element wire itself.

2. The glow plug lights but the engine will
not continue running once the battery is

disconnected (this is usually an indication

of the microscopic particles discussed

earlier).

3. Glow plug lights, the 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.
