Installing the Engine in the Airframe
Properly installing the engine to either the airframe or an engine test stand for break-in is crucial
to getting the most power and longest life from your engine.
WARNING: Always attach the engine mounting ring to a flat plate surface, such as
6–8mm plywood or carbon ber plate.
WARNING: Never use a standoff between the rewall and the mounting ring. Vibration
between the standoff and the mounting ring will damage the mounting ring and cause
the engine to separate from the airframe.

EN

1. Install the engine on the airframe with Cylinder
#1 in the top (12:00) position (Cylinder #1 is
above the Evolution Engines logo). You can
modify this position if you are using the op-
tional collector ring and you want the exhaust
to exit the cowl in a specific direction.
10-15mm
3. Relieve the rewall to make sure there is
at least 10–15mm (3/8–5/8 in) separation
between the carburetor and the firewall
for smooth airflow to the carburetor and to
allow adequate movement of the choke plate.

2. Use three steel screws (not included) to attach
the engine mounting ring to the firewall. The
size of the mounting ring screws will vary
depending on the aircraft. Always use the
largest size screw that will fit through the
mounting ring.
To keep the engine from coming loose in flight:
Firewall with blind nuts installed: Always
use split washers between the mounting
ring screws and the mounting ring.
Firewall with through bolts installed:
Always use nylon locking nuts with bolts
through the firewall.

EN

4. Make sure the fuel tank is no farther than 100mm (4 in) from the back of the rewall.
The center of the fuel tank should be in line with the carburetor to prevent fuel siphoning.
• You do not need to use a fuel pump with Evolution radial engines
• Always use a fuel lter inside the fuel tank
• We recommend using medium (3mm) or large (3.5mm) inner diameter fuel line
• Make sure there are no sharp bends in the fuel line between the fuel tank and the engine.
5. Attach the throttle servo linkage to the throttle bellcrank on the engine mounting plate.
Attaching the Included Glow Plug Harness
Your engine includes a 7- or 9-cylinder glow plug harness. Attach the red wired harness to
each of the cylinders and run the battery lead to a convenient mounting point for your glow
plug connector. We recommend installing the glow plug connector in the cowl or the side of
the fuselage. Remove one of the rear crankcase cover bolts. Attach the black wire to the bolt
and install the bolt in the crankcase cover.
Keep the overall length of both the red and black glow harness wires as short as possible
so the highest possible voltage will reach your glow plugs.
Glow Plug Starting Battery
The starting battery or on-board battery (whichever you prefer) should be a 1.2 V 6000–8000
mAh battery pack. We’ve had success building a pack of (6) 1300–1600 mAh NiCd (preferred)
or NiMh (takes longer to cycle to full capacity) 1.2v battery cells wired in parallel so the total ca-
pacity is 7800–9600 mAh. The total draw on 7 glow plugs at 2.2–2.7 amps per plug is 15.4–18.9
amps. With a 7800–9600mAh battery pack, you can expect about 30 minutes of ‘on-time’.
Once the engine is broken in, you will likely find that the engine idles and runs very well
without an on-board battery.
Installing On-Board Glow Drivers
Although Evolution Radial engines run just fine without constant glow heat applied, the use
of on-board glow drivers allows for easier engine starting and can ensure adequate heat in the
glow plugs at all times. This is particularly important on radial engines where oil collects in the
lower cylinders. SonicTronics/McDaniel RC on-board glow systems work very well with Evolution
radial engines.
7-cylinder applications: MCD477
9-cylinder applications: MCD479
We recommend installing the glow driver socket on the side of the cowl or fuselage and keeping
the battery wires as short as possible. Longer wires between the battery pack and the glow
drivers will reduce the amount of glow plug heat.
Attach the ground wire to one of the engine backplate screws or the crankcase.
Engine Cooling Requirements
It is very important to consider adequate cooling inside the airplane cowl. Engines require
a cooling airow exhaust:intake ratio of 3:1 to 5:1. A large open cowl may lead you to believe
there is adequate cooling; however, you must make sure air is flowing through the cowl and
the cylinder head fins. Achieving the proper ratio typically requires cowl and/or engine
baffles to reduce the open intake area.
1. Ensure there is adequate cooling air moving through the cylinder head cooling ns.
The intake air tends to move through the path of least resistance (between the cylinders)
instead of through the cylinder cooling fins.

EN
7
2. If necessary, add baffles to the engine to prevent air from moving between the cylinders.
Engine baffles force cool air through the cooling fins and greatly reduce the intake area
in the front of the cowl.
3. Add cooling bafes to the engine cowl between the top of the cylinder heads and the inside
of the cowl. Do not cover the engine exhaust pipe with the baffles. This needs cool air over
it to prevent exhaust valve damage.
Propeller Selection
Propeller selection is critical for proper engine operation. You can nd recommended propel-
lers and operating RPM ranges in the specification chart. Evolution radial engines have a lower
operating RPM range and greater torque within that range that require more blade pitch and
increased in-air pitch speed for your airplane.
To increase climbing and acceleration: Increase propeller diameter and decrease blade pitch.
To increase top speed: Decrease propeller diameter and increase blade pitch.
Make sure the propeller is securely mounted to the crankshaft before attempting to start
the engine.
1. Remove the wire circlip from the crankshaft in front of the propeller nut.
2. Install the propeller on the crankshaft.
3. Secure the propeller with the hexagonal nut.
4. Securely fasten the circlip on the outside of the hexagonal nut.
WARNING: NEVER start the engine without the circlip securely fastened. Doing so may
result in serious injury, as the propeller may become loose once the engine is started.
Fuel Selection
Evolution radial engines only require 6–7% synthetic oil after the break-in process. There is no
need to use fuel with nitro content higher than 10%. Adding additional oil to the fuel will reduce
the engine RPM. Please refer to the following chart for fuel recommendations.
Depending upon your choice of oil, you may nd that the engine feels ‘dry’ at the end of a ight
when using 6–7% oil. If you want, you can use 8–9% oil with any mix of ying fuel.
Tip: Many users combine one gallon of a good quality 15% nitro fuel (with 18% oil content)
with a gallon of pure methanol to achieve a 7 1/2% nitro and 9% oil mixture.

Engine Break-In Process
A good break-in process is essential to the longevity and performance of your Evolution radial
engine. You can complete the break-in process by either mounting the engine on a test stand
or on an airframe. If you choose to mount the engine on an airframe, remove the cowl during
break-in to ensure adequate cooling.
Specific fuel is required for the break-in process. Please refer to the chart above for the proper
fuel. Break-in fuel contains additional oil compared to fuel you will use for everyday flying. The
additional oil is critical for cooling and removing break-in debris from the engine.
During break-in, run the engine for 3–4 minutes at a time, allowing the engine to cool between
runs. Vary the throttle between idle and ¾ throttle for the rst 30 minutes of engine run time.
The engine break-in process will be complete after the rst 3 hours of engine run time and
you can begin tuning the engine for normal flying.
Checking for a Flooded Cylinder
Because of the nature of radial engines it is not uncommon for the lower cylinders to accumulate
excess fuel or oil either in storage or during the priming process. Before beginning the starting
process be sure to:
1. Rotate the propeller by hand. During the rotation, if you encounter a point where there is seri-
ous resistance to the rotation, STOP. This is an indication of a flooded cylinder and what you
are feeling is hydraulic lock. Any further attempts to force the rotation of the engine can result
in damage to the cylinder or conrod.
2. If you encountered hydraulic lock, remove the glow plug from the lower two cylinders and the
engine should rotate freely. Continue to rotate until all the excess fluid has been removed
from the cylinder.
3. Reinstall the glow plug and continue with the starting process.
Starting the Engine
Use a high quality gear oil to lubricate the outer parts of the valve train at the beginning
of each flying day.
1. Fill the fuel tank with fuel.
2. Power off or disconnect the glow driver.
3. Make sure the fuel lines are properly connected to the carburetor.
4. Open the throttle to full open. The carburetor barrel should be fully opened.
5. Place the choke lever over the carburetor opening.
6. Rotate the propeller 3 or 4 times until you see fuel moving through the fuel lines.
7. Remove the choke lever from the carburetor opening and move the throttle stick to ¼ throttle.
8. Power on or connect the glow driver battery. Make sure the glow driver battery is
fully charged.
9. Start the engine with an electric starter.

EN

Engine Tuning
The break-in settings for the carburetor needles are:
High-speed needle: 2 1/2 turns open
Tip: For the initial break-in, open the high speed needle to 1-1/2 turns before starting.
Low-speed needle: 2 turns open
Use a tachometer (HAN111 or HAN156) to tune the engine based on RPM.
WARNING: Always adjust the carburetor from behind the propeller. Keep all loose
items away from the propeller at all times. Never reach over or around the propeller.
1. Start the engine.
2. Move the throttle stick up until the engine is running at approximately 2,000 rpm.
3. If you are using separate exhaust pipes, use a temperature gun to make sure hot exhaust
is exiting all engine cylinders. If using a collector ring, make sure that each cylinder is of
a similar temperature to the others, indicating that it is running.
4. Move the throttle stick up to full (open) throttle.
If the engine runs rough or if some cylinders are not operating, the fuel mixture is too rich.
Lower the rpm to approximately to 2000 and lean the high speed needle valve by 1/8 of a turn.
5. Repeat Step 4 until the engine is running reliably at full (open) throttle. Proceed with the
break-in process described above.
High-Speed Needle Tuning
Once the engine is running reliably at full (open) throttle:
1. Lean the high-speed needle 1–2 clicks at a time.
2. Wait 2–3 seconds for the engine to respond. Radial engines do not respond immediately
to tuning changes.
a. If there is an increase in RPM: Lean the high-speed needle an additional 2 clicks and
wait for the engine to respond to the tuning change. If there is no increase in RPM after
the change, turn the high-speed needle back to its previous position.
b. If there is a decrease in RPM: Richen the high-speed needle 4 clicks and wait for
the engine RPM to stabilize.
3. Repeat Step 2 until you determine the maximum RPM with the fuel and propeller
you selected.
4. Richen the high-speed needle until the RPM lowers approximately 10% of the maximum
RPM (Example: If the maximum is 6,500 RPM, richen the high-speed needle until the RPM
drops to 5,900 RPM). Richening the high-speed needle allows the RPM to increase when
the airplane is flying. Further adjustments can be made after flying the engine to fine-tune
this needle position. This is a safe place to start to avoid overheating and an engine
flame-out.
Low-Speed Needle Adjustment
Low-speed needle adjustment controls the fuel/air mixture at idle and the quality
of the transition between idle and wide open throttle.
Tip: The use of an on-board glow driver will hide the effects of a poor low-speed needle
setting. When you are tuning the low-speed needle, turn the on-board glow driver off and
on to check the engine RPM response at idle.

EN
10
Test
1. Allow the engine to run at idle with the on-board glow driver ON. Observe the engine RPM.
2. Turn the on-board glow driver OFF.
If the engine RPM immediately drops, the low-speed needle is too rich. Lean the low-speed
needle (turn clockwise).
If the engine continues to run at the same RPM with the on-board glow driver OFF,
the low-speed needle setting is close to ideal.
Low-Speed Needle Tuning
1. Adjust the high-speed needle for the current conditions.
2. With the on-board glow system off (if using one) or the glow starting battery disconnected, al-
low the engine to idle for 10–15 seconds. Rapidly advance the throttle from idle to full open.
If the engine transitions with no hesitation, the low-speed needle is adjusted perfectly.
If the engine slowly responds to throttle change and gradually reaches peak RPM, the
low-speed needle is too rich. Lean out the low-speed needle (turn clockwise) 1/8 turn
and test again.
If the engine immediately stops running, the low-speed needle is lean. Richen the low-speed
needle 1/8 turn and test again.
3. When the low-speed needle is adjusted correctly, check the high-speed needle setting again.
4. When you are satisfied with the needle settings, you should not need to adjust the low-
speed needle again. The low-speed needle setting is mechanically controlled and it does
not change with atmospheric conditions.
Maintenance
There are a few things you must do to ensure proper operation of your Evolution radial engine.
1. Use a high-quality gear oil to lubricate the outer parts of the valve train at the beginning
of each flying day.
2. Use a high-quality, after-run oil such as Evolution Blue Block (EVOX1001 or EVOX1002) at
the end of each day’s flying. After-run oil protects the inside of the engine from corrosion
and un-burnt fuel in the crankcase.
How to Apply Evolution Blue Block After-Run Oil
1. At the end of the ying day, empty the fuel tank.
2. Attach the glow starting battery to the plugs, and, with the engine at the normal starting
throttle position, start the engine.
3. With the throttle at idle, allow the engine to die of fuel starvation.
4. With the throttle still at idle, restart the engine and allow it to die. Repeat as necessary
until the engine will not start. You have now insured that most all of the un-burnt fuel is
out of the engine crankcase.
5. Remove the glow heat.
6. Remove one of the pushrods from the number one cylinder and then remove the
cam follower pin. You now have access to the crankcase to insert the after-run oil.
7. Insert 5–10ml of EVO Blue Block After-Run Oil through the cam follower guide.
8. With the throttle wide open and no glow heat applied, rotate the engine with an electric
starter, or by hand, through 8–10 revolutions to disperse the oil throughout the engine.
9. Replace the cam follower pin and the pushrod. Leave the throttle wide open. Your
engine is now ready for short term storage and awaits its next day at the field.

EN
11
Evolution Blue Block After-Run Oil has been proven to provide long term protection against
corrosion when applied immediately at the end of the flying day. Even waiting overnight
before applying after-run oil will greatly increase the chances of corrosion within your engine.
Take care of your investment. Please do not believe the claims of the fuel companies that
claim “No need to use after-run oil”. They don’t own your engine!
3. Occasionally, you will need to adjust the valves. Adjust the valves the rst time after one
hour of engine run time. After the first hour, monitor the valve lash and adjust the valves
as needed. Adjust the valves when the engine is cool. The lash is set at 0.1mm–0.25mm
at the factory.
Evolution Radial Valve Adjustment Guidelines
1. Place the engine in a position (on or off your airplane) that allows you easy access
to the valves on all the cylinders.
2. Remove the glow plugs from all the cylinders. It is much easier to determine Top Dead
Center (TDC) without the compression caused by installed glow plugs.
3. Attach a propeller or other turning device (such as a short block of wood with the
appropriate hole for the crankshaft) to the crankshaft and tighten it so you can easily
rotate the crankshaft throughout this process.
4. Start with the number 1 cylinder (this should be the upright cylinder above the
Evolution logo).
a. Rotate the crankshaft counter-clockwise and observe the pushrod movement.
b. Note when you see the exhaust and then the intake pushrod move up to open
the valves. This will occur during one rotation of the crankshaft.
c. When the piston reaches the top of the cylinder during the next rotation,
you are at the TDC of the compression/firing stroke.
d. Position the piston at TDC of the compression/firing stroke. It is helpful to place
a short piece of wooden dowel. (Don’t use steel, as you can mar the inner surface
of the cylinder.)
5. Use a feeler gauge to check the valve lash between the rocker arm and the top
of the valve.
a. We recommend setting the valve lash as close to 0.1mm as possible. If the valve lash
is between 0.1 and 0.15mm (.004–.006”), you do not need to adjust the valve lash.
The settings for the intake and exhaust valves are the same.
b. Adjust the valves by loosening the locking nut and adjusting the screw until you can
just feel the drag of the .1mm (.004”) feeler gauge as you pull it between the valve
and rocker arm.
c. Tighten the locking nut and recheck the valve clearance. Sometimes when tightening
the nut, the adjustment will change slightly.
6. Because the cam gear of our engines is a shared cam gear with all the cylinders and
rotates at a 1:6 ratio, there are actually 6 different positions on the cam gear that need to
be checked. Repeat step 4 & 5 above four more times to check each of these positions. If
you find that the valve lash is smaller, readjust that valve. If it is greater, do not readjust
the valve. A little loose is safer than too tight.
7. Now move onto the next cylinder in an counter-clockwise directions and repeat steps
4 through 6. Do this for all cylinders.
Congratulations. You have now completed the valve adjustment process. This
maintenance should not be required again for another 10 hours of running time.

Einbau des Motors im Rumpf
Montieren Sie den Motor zum Einlaufen lassen korrekt im Rumpf oder auf einem Motorprüfstand
um die beste Leistung und Langlebigkeit zu erhalten.
WARNUNG: Schrauben Sie den Motormontagering immer auf eine flache Oberfläche
wie 6 - 8mm Sperrholz oder eine Kohlefaserplatte.
WARNUNG: Verwenden Sie zwischen Motormontagering und Motorspant keine
Distanzhülsen. Die Vibrationen zwischen Distanzhülse und Montagering beschädigen
den Ring und trennen den Motor vom Rahmen.

1. Montieren Sie den Motor im Rumpf mit dem
Zylinder Nr. 1 auf der 12:00 Position. (Zylinder
Nr. 1 ist über dem Evolution Logo).
Sie können diese Position mit dem option-
alen Kollektorring modizieren wenn Sie den
Auspuff an einer bestimmen Stelle durch die
Cowling (Motorhaube) führen wollen.
10-15mm
3. Lassen Sie zum Brandschott vom Vergaser
min 10- 15mm Abstand um einen guten Lufts-
trom und Bewegungsfreiheit des Chokehebels
zu ermöglichen.

2. Verwenden Sie drei Stahlschrauben (nicht
im Lieferumfang) um den Motorhalter an das
Brandschott zu schrauben. Die Größe der
Schrauben variieren abhängig vom Flugzeug.
Verwenden Sie immer die größte Schrauben-
größe die durch den Ring paßt.
Um den Motor am lösen zu hindern:
Brandschott mit Einschlagmuttern:
Verwenden Sie immer Federringe
zwischen Schrauben und Montagering.
Brandschott mit Bolzen:
Verwenden Sie immer Nylon Stopmuttern
mit Bolzen durch das Brandschott.

4. Stellen Sie sicher, dass der Kraftstofftank nicht weiter als 100mm von der Rückseite des
Brandschottes entfernt ist. Die Mitte des Kraftstofftankes sollte dabei auf einer Linie mit
dem Vergaser sein, um ein Absaugen des Kraftstoffes vom Motor weg zu verhindern.
• Sie benötigen bei Evolution Stermotoren keine Kraftstoffpumpe.
• Verwenden Sie immer einen Kraftstofflter im Tank.
• Wir empfehlen die Verwendung von 3,0 mm oder 3,5mm (Innendurchmesser)
Kraftstoffschlauch.
• Stellen Sie bitte sicher dass keine scharfen Knicke im Kraftstoffschlauch zwischen
Tank und Motor sind.
5. Montieren Sie das Gasgestänge an dem Gaswinkelhebel auf der Motormontageplatte.
Anschluß des Glühkerzensteckers
Ihr Motor wird mit einem 7 oder 9 Zylinder Glühkerzensteckerkabel geliefert. Schließen Sie das
rote Kabel an jeden einzelnen Zylinder an und führen den Akkuanschluß an den Glühkerzena-
kkuanschluß. Wir empfehlen den Glühkerzenanschluß in der Motorhaube oder an der Seite des
Rumpfes zu montieren. Schrauben Sie eine der hinteren Kurbelwellengehäusebolzen los und
befestigen Sie den schwarzen Draht daran. Schrauben Sie den Bolzen wieder fest.
Halten Sie die Länge des roten und schwarzen Kabel so kurz wie möglich, dass die höchste
Stromspannung die Kerzenstecker erreicht.
Glühkerzenakku
Der Start oder Bordakku (was Sie bevorzugen) sollte 1,2 V 6000 - 8000 mAh Kapazität haben.
Ein guter Weg ist ein Paket von 6 Zellen 1300 - 1600mAh NiCad (vorzugsweise) oder NiMH (diese
brauchen einen längeren Zyklus bis zur vollen Kapazität) parallel geschaltet, dass die Gesamt-
kapazität 7800 - 9600mAh beträgt. Der Stromverbrauch der sieben Glühkerzen bei 2,2 bis 2,7 A
beträgt 15,4 bis 18,9A. Mit einem 7800 - 9600mA Akku haben Sie so eine nutzbare Zeit von 30
Minuten. Nach dem Einlaufen lassen werden Sie feststellen, dass der Motor auch ohne Bord-
glühzündung sauber und ruhig läuft.
Montage des Bordglühkerzenanschluß
Obwohl Evolution Sternmotoren auch ohne konstant beheizte Glühkerzen laufen bringt die
Verwendung eines Bordglühkerzenaschlusses ein einfacheres Starten. Das ist bei Sternmotoren
wichtig bei dem sich Öl in den unteren Zylinder sammeln kann. Das Bord Glühsystem von
SonicTronics/McDaniel arbeitet sehr gut mit Evolution Stermotoren.
7 Zylinder: MCD477
9 Zylinder: MCD479
Wir empfehlen den Glühkerzenanschluß auf der Seite der Cowling oder des Rumpfes
einzubauen um die Kabelzuleitungen so kurz wie möglich zu halten.
Verbinden Sie das Massekabel mit einer Kurbewellengehäuseschraube.
Kühluftanforderungen
Es außerordentlich wichtig dass Sie für eine adäquate Kühlung unter der Cowling sorgen. Der
Motor benötigt ein Auslass/Einlass Verhältnis vom 3:1 bis 5:1. Eine große offene Cowling (Mo-
torhaube) kann Sie zu der Annahme bringen, dass ausreichen Kühlluft eintritt, Sie müssen aber
auch davor sorgen dass sie durch die Cowling an den Zylinderköpfen strömt. Das Erreichen des
richtigen Verhältnis erfordert Luftleitbleche in der Cowling um die offene Fläche zu reduzieren.
1. Stellen Sie sicher dass ausreichende Kühlluft die Kühlrippen der Zylinder erreicht. Luft hat
die Eigenschaft den Weg des geringsten Wiederstandes zwischen den Zylindern zu wählen
statt den Weg zwischen den Kühlrippen.
