1General Safety:
Read and understand this Owner’s Manual before operating your engine. You can help to
prevent accidents by being familiar with the controls and observing safe operating
procedures.
Operator’s Responsibility:
1.1 The operator should know how to stop the engine quickly in case of any
Emergency.
1.2 A safety zone around the propeller should be established in which no person or
object is allowed to enter. Install a guard around the propeller when appropriate.
WARNING
1. Observe all safety precautions when working around the propeller.
2. Exhaust contains poisonous carbon monoxide, a colorless and odorless gas. Breathing
Carbon monoxide Can cause loss of consciousness and may lead to death.
3. Never run your engine in an enclosed space. Always allow for appropriate ventilation.
4. Observe precaution around the muffler. The exhaust system gets hot enough to ignite
Some materials.
5. Keep flammable materials away from the engine.
6. Petrol is extremely flammable and is explosive under certain conditions. Do not smoke
Or allow Flames or sparks where the engine is operating

3 Engine Installation & Getting Started
3.1Hardware Installation
1. Do not install the ECU, fuel pump and CDI to the engine or motor mount. The vibration
Will damage the hardware. Route the ECU to a location inside the aircraft and mount it
Where vibration is minimal. The ECU does not produce excessive heat and can be
Encapsulated in foam to isolate it from vibration if needed.
2. Refer to the diagrams above and make sure wire harness of EFI are well designated &
Connected.
3. When the engine is mounted, check all the wiring harness are connected correctly & the
reliability for the connection. It is necessary to ensure the wiring harness does not rub
against the body part.
4. When the engine is installed, related shock absorption is required, and screw glue is used
to Ensure reliable installation.
5. Connect the thin fuel line from the output port of the fuel pump to the oil inlet of the
throttle valve, push tubing past locking ring in blue to produce a proper seal and lock it, in
reverse push the locking ring to release the fuel line (do not fold or twist the fuel line).
6. The fuel pump is installed close to the fuel tank. It is recommended not to be higher than
the fuel level, and ensure fuel inlet fuel line & fuel outlet fuel line be not bent or folded;
the thin fuel line connecting fuel pump & the engine should be kept at least 30cm in length
in order to reduce fuel pressure change.
8. Install the fuel filter between the fuel pump inlet and the fuel tank, ensure the fuel line is
connected properly in place; tighten the non-falling nut for fuel line.
9. Any 3 Cell Lipo or 4 Cell Lifepo4 or equivalent battery with a minimum of 2000 mAh
rating will run the engine for up to 2 continuous hours (5000 RPM/H). DLE60cc engine is
the latest version with CDI voltage from 4.8V-14V. Gaskets for DLE engines (Since
September 2021) are in the latest material without air pollution restricted by some
countries.

3.2 Throttle Setting
1. Throttle commands use standard RC TX/RX or flight controller. The voltage of throttle
servo installed on the engine is 6V-7.4V by RX or Flight Controller Channel
2. Before starting the engine, adjusting the exponential rate of TX throttle curve or flight
controller to get the desired throttle response with throttle air valve, which affects the
engine performance
Full Throttle On Full Throttle Off
3. Our EFI system does not need extra Throttle Kill Switch, the engine will stop and
automatically the power for fuel pump is cut off when throttle air valve is fully off.
4. For UAV project with the engine applied, providing power to the enable line of
ECU,when the signal of flameout is given, the enable line on an optional module (not
recommend) will stop the engine. For most flight controllers on the market, 10% rate for
idle RPM is set and will not stop the engine until turning off the button on the flight
controller. Suggest the user to set up the idle rate on your TX or flight controller for the
first time to operate the engine. Properly adjust and set up the throttle curve and rate to
avoid the damage of throttle servo by dead steering.
