DLE120T4 120cc Four Cylinder Gasoline Engine
The DLE120T4 120cc four cylinder gasoline engine is a two-stroke piston engine. It is DLE's smallest displacement four cylinder aeromodel engine.
This compact power plant offers a smooth delivery of power. It is designed for hobbyists who need high performance in a small package.
The four-cylinder configuration reduces vibration compared to larger twins. This results in a more stable flight experience for your model.
Engineers optimized the displacement to balance weight and thrust. This makes it a versatile choice for a variety of aircraft scales.
The engine delivers an impressive 12HP at 7500rpm. This power-to-weight ratio ensures your model maintains excellent agility in the air.
For optimal operation, use clean 92 unleaded gasoline or higher. Maintain a strict 30:1 oil ratio for engine longevity.
Consistent fuel quality prevents carbon buildup in the cylinders. This helps maintain the peak 12HP output at 7500rpm.
Do not mix different brands of lubricating oils. Doing so may lead to residue and carburetor blockage.
Avoid mixing synthetic and mineral oils. Using one consistent brand ensures the best internal lubrication for the piston.
Ensure the ignition voltage stays between 4.8V and 12V. This ensures consistent spark timing and reliable engine starts.
A stable voltage prevents ignition failure during flight. Always check your battery levels before every takeoff to ensure safety.
Check the recommended propellers before installation. Options include 27x10, 26x12, and 28x10 for different flight needs.
Matching the propeller to your airframe is vital. The right choice maximizes static thrust and fuel efficiency during operation.
Regular maintenance of the spark plugs and air filters will extend the engine's life. Follow the manual for specific service intervals.
Proper installation of the exhaust system helps manage heat. This prevents overheating during extended high-throttle flight periods.
