Safety Tips and Warnings
● This engine is not a toy. Please place your safety and the safety of
others paramount while operating. DLE will not be held responsible
for any safety issues or accidents involving this engine.
● Operate the engine in a properly ventilated area.
● Before starting the engine, please make sure all components
including the propeller and the engine mount are secure and
tight. It is strongly recommended that a screw sealant is used
(Great Planes Threadlocker GPMR6060) during engine installation.
● During the break-in period, it is recommended that the engine be
installed on the aircraft or a test stand with an appropriate shock
absorber. Otherwise it is probable that vibration could rebound
back to the engine and serious damages may occur during the
break-in period. Break-in should be considered about the fi rst
2
3-5 gallons you run in the engine.
● For your safety and the safety of others, please do not stand
in front of the propeller or inline with the propeller when the
engine is running. Keep onlookers away from the running engine,
especially small children.
● Always use a balanced spinner and a balanced propeller. An
unbalanced spinner or propeller combination will cause high
levels of vibration and may cause the propeller shaft to break.
Always use a lightweight, high quality spinner on your engine.
Heavy spinners could cause the propeller shaft to break. Evenly
and securely tighten the spinner and propeller to the engine to
prevent them from being thrown off the engine while running.
● Never use a propeller that has hit the ground. Even though it
may look good from the outside, it may be cracked on the inside
which may cause it to disintegrate while in use. Do not use a
nicked, cracked or split propeller.
● Keep foreign objects away from the propeller. Make sure that
nothing can be “sucked in” by the propeller.
● Never start the engine on loose gravel or sand.
● Do not attempt to stop the engine by throwing anything into the
path of the propeller.
● Do not use silicone fuel line because it will be dissolved by the
fuel. Use gasoline approved rubber fuel line. Always secure the
fuel line away from the cylinder head. The engine’s heat can
damage the fuel line.
● Never touch the engine immediately after a run. The engine will
be hot.
● Before transporting your model, remove all the fuel from the
fuel tank and fuel lines.
● Always use high-quality oil intended for 2-stroke (2-cycle) engines.
It's a good idea to use a petroleum-based 2-cycle motor oil like
Lawn Boy All Season - Ashless oil for the break-in period.
●
Do not install your throttle servo inside the engine compartment.
Doing so could cause radio interference. When practical, install all
electronic radio devices at least 12" [305mm] away from the engine.
● The throttle and choke pushrods should be non-metallic.
● If the engine is not to be used for more than a month, drain the
fuel tank and remove any fuel from inside the carburetor. Do this
by running the engine at idle until it quits by running out of fuel.
Keeping gasoline inside the carburetor over an extended period
of time will damage the diaphragm valve and clog passages
inside the carburetor. Because the carburetor is more complicated
3
than those used in glow engines, keep the fuel clean by using a
fuel fi lter. Use a fi lter intended to be used with gasoline engines.
Metal fi lters intended for glow engine are too coarse and will
not screen out fi ner particles.
● Always fi lter your fuel by using an appropriate fi lter before putting
it into the airplane’s fuel tank.
● Gasoline is extremely fl ammable. Keep it away from an open
fl ame, excessive heat or sources of sparks.
● Do not smoke near the engine or the fuel tank.
● This engine was designed for use in a model aircraft. Do not
attempt to use it for any other purpose.
● Always install an ignition system on/off switch on the aircraft used.
● Caution: Running the engine with a lean fuel mixture will cause
the engine to overheat and burn the electrode of the spark plugs.
Pay close attention to the High-speed Needle adjustment. Running
the engine with the proper fuel mixture will make the spark plugs
appear yellow at the ignition point.
● For optimum performance please use fresh or recently purchased
87-93 octane gasoline with a 30:1 fuel/oil mixture
.

● Excessive running of the engine at idle speed can result in
carbonized spark plugs.
● Keep the surface of the engine clean to ensure proper heat
dissipation. Ensure proper cooling/ventilation around both
cylinders with adequate air exhaust.
●
To avoid permanent damage to the electronic ignition system, NEVER
rotate the propeller on your DLE engine with the electronic ignition
system switched on and the plug not installed in the plug cap.
● If you choose to use the optional TX activated Opto Gas Engine
Kill Switch (DLEG9205) it is strongly recommended that you
install the TX activated kill switch between the on/off switch and
the ignition. The on/off switch provides an added safety feature in
the event the TX activated kill switch does not function properly.
This is especially important during the starting sequence as it
requires the on/off switch to be in the ON position before ignition
can occur.

Installation Instructions
Prepare the engine for installation
1. Check to see that all screws and bolts are tight. Check carefully for
any cracks, broken or missing parts. Tighten or replace any damaged
or missing parts before proceeding.
2. Install the silicone wire cover over the pick-up lead coming from
the engine (cut the excess silicone wire cover) and connect the lead
to the pick-up lead from the Electronic Ignition Module. Secure the
connection with the included three pin connection securing clips.
3. Connect the on/off switch lead to the red connector from the
Electronic Ignition Module using the lead from the on/off switch or
with the included three pin connector with pigtail. Use one of the
included three pin securing clips to secure the connection.

4. Connect the ignition module battery to the on/off switch. Any
4.8-8.4V, 1000mAh and above capacity battery will work well for
this. Use heat shrink tubing to secure this connection. Optional:
Install the TX activated Opto Gas Engine Kill Switch (DLEG9205)
between the on/off switch and the ignition as shown above. This is
especially important during the starting sequence as it requires the
on/off switch to be in the ON position before ignition can occur. The
kill switch LED should be installed on the exterior of the aircraft so
that it’s visible from the front of the aircraft. This is to ensure that
the person starting the engine is aware that the ignition is armed.
If properly installed as shown above an illuminated red LED indicates
that that the ignition is armed.
5. Install the ignition on/off switch on the aircraft so that it is easily
accessible from outside the aircraft.
6. Install the ignition module and battery
securely in the airplane forward area.
It is recommended that a thin piece
of foam rubber is placed between the
module and the mounting surface and
that Velcro® strap is used to hold the
6
module in place.
7. Secure all connections with heat shrink tubing. (not supplied)
8. Install the remaining silicone wire covers over the ignition wires.
9. Install the spark plugs into the cylinders (7-8lbs torque). Do not
overtighten.
Installing the DLE-60 on Your Airplane
Note: The DLE-60 must be installed on a minimum 3/8" [9.5mm]
plywood fi rewall.The fi rewall must be securely glued to the airplane.
Use triangle stock and pin the fi rewall with hardwood dowels to
reinforce the fi rewall glue joints. Never install the DLE-60 onto a
fi rewall thinner than specifi ed because it may fail due to the power
of the engine.
Note: The overall length of the engine from the back of the engine
mount to the face of the propeller drive hub is 6.69" [170mm].
1. Use the supplied template (on the back cover of this manual) to
drill the engine mounting bolt holes.
2. Install (4) 5mm blind nuts (not
included) into the back side (nonengine side) of the fi rewall. Install
the engine to the fi rewall using
(4) 5x45mm SHCS with 5mm
lock washers and fl at washers
(not included) with the included
standoffs. Use threadlocking
compound, such as Great Planes® Pro™ Threadlocker (GPMR6060),
on the screws where they thread into the blind nuts.
3 Install the fuel tank in the airframe. Use only gasoline approved
fuel tank and lines and a gasoline safe fuel tank stopper. One line
should go to the carburetor and the other is to be used as a vent
(a vent line is simply an open ended fuel line from the fuel tank
which exits the engine compartment or the fuselage; most vent lines
exit at the bottom of the fi rewall).You can fi ll the tank by using the
carburetor line as fi ll line if you have access to it or install a third
line to be used as fi ll line. Installing a third line is the cleanest and
easiest way to add fuel. An alternative fueling set up is a 2-line
system with a T-fi tting approved for gasoline use. Be sure to use a
fi ller plug with either a 2 line or 3 line set-up. It is a good idea to
add an extension to the vent line as shown, that goes up and to
the rear of the tank. This helps to avoid draining fuel from the tank

4. Install the throttle servo at
least 12" [305mm] away from
the engine. Make sure that
you get the carburetor’s full
range of rotation with your
servo travel. Be sure to use a
non-metallic linkage (as shown
below). A high torque metal
gear servo is recommended
to operate the throttle.
