Engine Installation
The engine should be mounted on a motor box that will in turn mount to the fuselage. A quadrilateral
shape (gradually increasing in size as it goes away from the motor) provides the best circulation
of air. The reason for using a motor box rather than mounting the engine directly to the fuselage
is that the cylinder(s) need enough room around them to provide proper airflow over and away
from them
The motor box should be sti ff enough to prevent engine vibration and it should also have a solid
firewall. The firewall of the motor box should be made from 1/4" aircra ft plywood for engines up
to 106cc, or 3/8" aircra ft plywood for engines in the 150cc class. For builders experienced with
making composite motor boxes; a com p arable strength should be at t ained.
It is absolutely vi t al to ensure a tension free mounting of the engine. The surface that the engine
is mounted on must be on an even plane (i.e., a flat and level surface) so that there is no strain
on the engine i t self. Again, this is a vi t al and critical requirement to avoid distorting the crank case,
ruining the engine, and voiding your warranty.
Mount the engine to the motor box with high tensile bol t s. Once mounted you now have a sub-
assembly that you can mount to your fuselage. S p acers can be made from hardwood dowels (3/4"
to 1") or machined aluminum bar stock to adjust your down and side thrust. These sp acers should
go between the motor box and fuselage and not the motor box and engine.
www.3w-modellmotoren.com

120 - 150i B2 / TS / CS front and rear Engine Manual
It is strictly prohibited:
To mount the engine directly onto sp acers for the following reasons:
a. If the sp acers are too long and/or not sti ff enough the engine could vibrate leading
to the cranksha ft s t arting to twist, further leading to the crank case being destroyed.
b. If sp acers are used to adjust the side and/or down thrust and this sp acing no longer
provides an even plane (i.e., a flat and level surface) the crank case will be distorted,
leading to the cranksha ft s t arting to twist, further leading to the crank case being
destroyed.
To mount the engine directly onto a large (wide) former or firewall for the following reason:
a. If the cylinder(s) is/are too close to this wide former or firewall, the floating air cannot
p ass freely over and then away from the cylinder(s). Cavi t ating hot air can/will overheat
the engine.
Engine Cooling
A proper cooling system is vi t al for any engine. An air cooled engine requires an appropriately
sized air in t ake. Also to keep this air cooling process working the incoming air must be exhausted.
Further, the exhaust air outlet should be four times (4X) the size of the cool air in t ake.
Example:
•10 square inches of air in t ake area would require
•40 square inches of exhaust air outlet area
It is up to you to insure that the air flows freely to, over, and away from, the hot cylinder(s) and
mu f fler(s). Please refer to Engine Ins t allation for motor box considerations, and to the following
ti ps on ba f fling.
Baffling
Deflecting of the air (ba f fling) to and over the cylinder(s) is highly recommended for engine cooling.
The idea is to get all of the cool air that is coming through the air in t ake opening(s) to hit the middle
of the cylinder(s) directl y, and then be forced over the cylinder(s), creating turbulent air moving
www.3w-modellmotoren.com

120 - 150i B2 / TS / CS front and rear Engine Manual
through the cylinder(s) fins. The freely flowing, but directed and turbulent air between the fins
provides the maximum cooling for an air cooled engine. Without ba f fling (meaning wood or
composite dampers that direct the airflow) the air will t ake the p ath of least resis t ance. Some
incoming air will bounce o ff the cylinder(s) and the rest will escape around the cylinder(s) without
coming into con t act with the cylinder(s).
Engine in pusher operation:
Impor t ant note! When engines are used operating in pusher configuration cooling ge ts critical and
special attention has to be given to an e f fective cooling method. A good cooling system layout
depends on the actual location (position) of the engine in the fuselage.
Operating temperature
To be able to check the cylinder head temperature ( CHT ) a thermo element has to be installed which fits
under the spark plug ( M 10 thread ). Optimum operating temperature range : 180°C - 220°C. In this range
piston, spark plug and combustion chamber will be free of remains. Maximum temperature of 270°C should
not be exceeded. During a certain time at full speed the temperature could be 250°C.
Colour of the spark plug should be : light or middle brown. A grey / gray colour is a typical sign for over
heating. Temperatures above 270°C are critical and over 300°C, piston can seize and could completely
damage the engine.
Temperatures below 180°C create remains ( carbon ) on the piston crown. Increasing remains hit the
cylinder and cause abnormal running noises ( knocking ) which will increase the load of the needle
bearings and can destroy them. Under extreme conditions the crankshaft can break and a complete
damage of the engine will be the result.
Rear induction
Carburetors, whether front or rea r, require a steady supply of fresh air. The best way to supply
air to a rear carburetor is by ins t alling an air scoop. Some have thought to drill holes into the
fuselage near the carburetor area rather than creating an air scoop for the carburetor. This does
not work, it fact it will create a vacuum e f fect that will draw the air away from the carburetor! Again,
you should ins t all an air scoop into the front of the plane which will supply air into the fuselage.
This air will then need to flow out of the fuselage. Drill exit holes into the rear area of the fuselage
for this purpose. Impor t ant: The interior of the fuselage must be sealed to prevent damage from
gasoline that sprays from the carburetor. Use a thin epoxy or other appropriate fuel proofing
method. Do not overlook this step as gasoline will melt some materials like S tyrofoam very quickl y.
www.3w-modellmotoren.com

120 - 150i B2 / TS / CS front and rear Engine Manual
Ignition
Consideration needs to be given to the placement of the electronic ignition module. A void placing
the module in the p ath of hot air. Mount the ignition module using the four supplied rubber gromme ts
so as to create a 1/16" gap between the ignition module and the mounting surface. Without this
1/16" gap the ignition module can overheat. Impor t ant: If the electronic ignition overhea ts it will
malfunction (e.g., backfiring or shutting down).
Ignition details:
• The red cable is positive (+)
• The ignition timing has been set at our factory
• When fitting a new ignition it is impor t ant to achieve the correct coordination of the sensor(s)
to the magne ts
Refer to our special ignition description for further information
Canister mufflers
To prevent damage to the header(s) a flexible support bracket is required to mount the canister(s).
The location for this bracket should be at the canister's center of gravit y. 3W canisters have a
reinforcement ring at this location.
www.3w-modellmotoren.com

120 - 150i B2 / TS / CS front and rear Engine Manual
We suggest creating two com p artmen ts in the front section of the fuselage by ins t alling a horizon t al
tray. Fuel t anks, batteries, and other equipment can be mounted on top of this tray; the canister(s)
being ins t alled below it. Close o ff the lower com p artment at i ts rear with an angled former. Locate
this former 1" behind the back of the canister(s). Next cut a hole in the bottom of the fuselage just
under the rear of the canister(s). In this way the air coming from the front of the model can flow
over the canister(s) and then be deflected by the angled former so as to exit through the hole in
the fuselage. Do not forget to reinforce around this hole.
Important:
This exit area needs to be four times (4x) as large as the intake area.
Propellers
• Only use propeller brands and sizes that are approved for your engine
• The propeller blades must be of the same length
• The propeller must be flat (Y ou can check for flatness by putting the propeller on a level
surface. The maximum di f ference of the blade heigh ts should be no more than 1/64".)
• The propeller ti ps must have an identical shape. This is especially impor t ant when using
3 or 4 blade propellers.
•Y ou must use a drill press to drill your propeller.
•Y ou must drill the propeller from the rea r.
• A drill guide is recommended, but the propeller washer can be used as a drill template. (Fix
the propeller washer onto the propeller in the center-bore using a bolt and nut. Drill one
hole; put one of the propeller bolts into the hole. Continue until the last bolt is used.)
• If you cannot hand tighten all of your prop bolts easily then you have not drilled the propeller
correctl y. This can lead to sheared propeller bol t s.
• Balancing your propeller is absolutely critical to the health of your engine. Y ou must keep
your propeller balanced. (Propeller balancers are available from DUBRO, and others.)
• Always remember that when the engine is running every person must s t ay behind the line
of the ro t ating propeller; never to the side or the front!
Carburetor settings
Before each engine is shipped it has to p ass QC and is then test run. We do a basic adjustment
of the carburetor needles at that point.
www.3w-modellmotoren.com

120 - 150i B2 / TS / CS front and rear Engine Manual
please refere to t able of tecnical specifications
Important: Do not remove the carburetor spring as the spring hel ps keep the carburetor butterfly
aligned properl y. Merely release the ends of the spring so that it no longer holds the butterfly
closed.
Carburetor Linkage
Included with your engine is a me t al bracket to extent your carburetor pushrod horn. Fix this
bracket onto the carburetor horn with a 2.6m machine screw and nut. Then solder the arm in place.
Refer to the at t ached illustration.
Note: The use of a so ft pushrod for the throttle (plastic or nyrod) is not recommended. Use a me t al
or carbon fiber pushrod with a plastic ball joint or plastic clevis at each end. This will keep your
RPM much more consistent and accurate around idle where it really coun t s.
Engine Break In
• Use a 2-stroke petroleum based oil (preferably ashless) as this type of oil has a good
honing e f fect which hel ps to break in the engine
• Use a mixture of 32-1 or even 30-1
• Use this fuel mixture for approximately 2-3 hours of run time
• Use a high Oc t ane unleaded fuel (from 92 Oc t ane is ideal)
www.3w-modellmotoren.com

120 - 150i B2 / TS / CS front and rear Engine Manual
We suggest s t arting the break in process of the engine on a test s t and; for approximately one
hou r. This time should be used to get familiar with the engine. Do not run the engine at full throttle
for more than ten seconds during this test s t and break in. The reason for this is that you are not
getting the normal cooling e f fect that you would if the engine was in a model that was flying.
Another method that can be used for break in would be to set the engine between 2000-2500 rpm
and let it run for 4 hours. A f ter that the engine would basically be broken in. Note: For break-in a
smaller propeller is recommended.
Important:
Remember that when the engine running ever
person must s t ay behind the line of the ro t ating propeller; never to the side or the front!
A f ter Initial Break In
• Use high grade fully synthetic 2-stroke oil
• Use the oil manufacturer's recommended gas to oil mixture
• Use a high Oc t ane unleaded fuel (from 92 Oc t ane is recommended)
•We use 3W 2-stroke oil in our engines here in German y, but there are other high grade
2-stroke oils that will perform well.
Note: The engine needs 12-20 hours running time for the break in process to be 100% complete.
www.3w-modellmotoren.com

120 - 150i B2 / TS / CS front and rear Engine Manual
Additional installation notes
• There must be a minimum 4" se p aration between anything at t ached to the receiver and
all things related to the ignition (i.e., the ignition i t self, and i ts wires, battery, and switch)
• Use a plastic spiral sheath to protect the ignition cables
• Never remove the sparkplug cap by using a mechanical aid like pliers. Only remove the
cap by hand using a twist/pull movement.
• The sp ark plug cap must be firmly seated to the sp arkplug. If the sp ark plug cap is not firmly
seated there is a very good possibility that you will experience radio interference.
• Use only ignition on/o ff switches recommended by 3W
•6 volts is required for the ignition.
• Do not skimp on your throttle servo. A high quality throttle servo is recommended for reliable
and accurate operation of the carburetor.
• Never fill the fuel t ank via the carburetor fuel line
• Use the same I.D. for t ank ventilation and the carburetor fuel line
• Use small plastic cable ties on all fuel line to fitting connections.
•We recommend cutting the fuel line in the fuel t ank in half. And, then joining them back
together with a brass tube. The brass tube preven ts a folding of the fuel line with could cut
the fuel supply for the engine (see t ank photo).
• The use of soldered on DUBRO barbs on the ends of the brass tubing is highly recommended.
Again, always secure the fuel line with small plastic cable ties.
Warning!
Failing to read and follow all of the instructions in this manual can lead to unsafe conditions and
damaged equipment. Here are some examples:
• Unbalanced propellers can damage the engine's ball bearings, needle bearings, even
www.3w-modellmotoren.com

120 - 150i B2 / TS / CS front and rear Engine Manual
cause the cranksha ft to break
• Incorrectly drilled propellers can lead to sheered propeller bolts further leading to acciden ts
and crashes
• Loose propeller bolts can also lead to sheered propeller bolts further leading to acciden ts
and crashes. Check these bolts before s t arting your engine.
• Flipping the prop with your hand or fingers can lead to serious acciden t s! Always use a
rubber stick to s t art the engine!
• Not having the plane secure can be lead to serious acciden t s. Depending on i ts size use
one, two, or more helpers to secure your model. Always tell your helpers to be ready for
the model to s t art at full power. Remembe r, these engines have a high power output.
• Do not put your finger(s), any items, or any other p ar ts of the body into the ro t ating propeller.
• Never tune the carburetor whilst engine is running! S top the engine. T une the carburetor
and s t art the engine again. Repeat this procedure until the carburetor is properly tuned.
• Make sure that no gasoline will be splashed into the hot mu f fler(s).
• Only 3W mu f flers, or mu f flers authorized by 3W with an accep t ance (test) number, should
be used.
• Only 3W -ignition systems should be used for proper operation.
Important:
Using unauthorized produc ts or failing to follow the instructions in this manual will void your
warranty immediately.
Pilots check list
We strongly recommend checking the following agenda for your own safety before s t arting!
• Check the propeller bolts for tightness
• Check that the spinner is firmly at t ached
• Check the propeller for possible damage
• Check to be sure you have the throttle position at idle
• Check all batteries
• Check servo functions
• Check to see that the ignition switch is OFF
• Check pressure (6-8 bar) system of retract (if applicable)
• Check all linkages for play
• Check your wheels for possible damage and easy running
www.3w-modellmotoren.com

120 - 150i B2 / TS / CS front and rear Engine Manual
• Check the wing mounting for tight fit and proper at t achment
• Check the canopy for tight fit and proper at t achment
• When s t arting the engine one person (minimum) has to hold the model
Starting Procedure
If you have read and understood this entire manual, and followed i ts recommendations, you are
ready to s t art your new engine.
• Use a rubber stick to s t art the engine. Never use your hand or fingers!
• Insure that your receiver batteries are charged and your receiver is on
• Insure that your ignition battery(s) are charged
• Insure that your transmitter is on, and that your throttle is set to low
• Insure that your plane is properly and safely anchored (use one, two, or more people if
necessary)
• Close the choke(s)
• Switch on the ignition
• Flip the propeller until the engine "po p s" (s t ar ts and sto ps quickly)
•W ait for the propeller to stop spinning, turn o ff the ignition, and open the choke(s)
• Switch the ignition back on
• Flip the propeller again until the engine s t ar ts
•W arm-up the engine for at least 20 seconds
• Due to the high power and torque of the engine(s) it is not recommended to open the throttle
abruptly
Precision tuning of the carburetor
The use of a t achometer is highly recommended. And, again, never adjust the needles while the
engine is running!
1. Using the t achometer tune the engine for maximum power with the high needle (H).
2. Again using the t achometer; richen the high needle (H) until the motor runs 100-200 RPM
less than the maximum RPM. Now you are tuned slightly rich on the high needle (H).
3. Let the engine run at idle for one minute. Check to see that the idle RPM remains cons t ant.
4. If the idle RPM drops until the engine sto p s; the low needle (L) is too rich. Lean the low
needle (L) until a cons t ant idle RPM is achieved.
5. Check the transition with a quick throttle advance. The engine should not sound strained
www.3w-modellmotoren.com

120 - 150i B2 / TS / CS front and rear Engine Manual
at any time. It should sound like it is making quick steady power; without any hesi t ation.
6. An optimally tuned engine will feel a bit rich a f ter a cold s t art. It will s t art to run right a f ter
it has warmed up for approximately one minute.
Trouble Shooting
Problem
The engine is flooded (the cranksha ft housing is filled with fuel).
Solution
Remove the sp ark plug; turn the engine to a position where the fuel runs out.
The engine s t ar ts a f ter being choked but then sto ps soon a f ter.
The low needle on the carburetor is probably too lean. Go back to the recommended settings
and adjust your carburetor from there. This problem may also indicate a dirty carburetor or
faulty ignition.
The engine runs rough and is vibrating strongl y.
Balance the propeller. Check the ignition timing. Check your plumbing for air/fuel leaks.
Check your sp ark plug for carbon and check the sp ark plug gap. Check the motor mount to
be sure it is rigid. Check to make sure the engine is mounted on a level surface so that the
crankcase is free of tension. Check the engine and propeller bol t s.
The engine doesn't reach a normal RPM at full throttle.
Check the carburetor settings. Check to see if the propeller is too large. V erify that you have
the correct mu f fler system. Check to see if the engine is overheating. Check the ignition
timing. Check the sp ark plug for defect. V erify you have the correct gasoline, oil, and have
mixed them with the correct ratio.
