DLE 111cc Gasoline Engine for Large-Scale RC Aircraft

A: The DLE 111cc Gasoline Engine is a high-displacement RC airplane engine designed for giant-scale model aircraft, large sport aircraft, scale models, aerobatic builds and professional aeromodelling applications.

A: The listed import price is US$1,260 for the DLE 111cc Gasoline Engine Standard Package. Final pricing may vary if installation support, propeller matching, workshop support or UAV prototype integration assistance is added.

A: The listed displacement is 111.2cm³, making it suitable for large and giant-scale RC aircraft applications.

A: The listed performance rating is 4.1HP at 7500 RPM.

A: The listed idle speed is approximately 1500 RPM. Stable idle depends on correct fuel mix, ignition setup, carburetor tuning and engine condition.

A: The listed static thrust is 25.5kg at 100m altitude and 22.3kg at 1800m altitude. Actual thrust depends on propeller, air density, tuning, fuel mix and aircraft setup.

A: The listed bore and stroke are 45mm × 35mm.

A: The listed compression ratio is 7.6:1.

A: The listed lubrication ratio is 30:1. Fuel/oil mixing should follow engine manual guidance and proper break-in procedure.

A: The listed spark plug type is NGK CM6.

A: The listed ignition voltage range is 4.8V–8.4V. Select the ignition battery and regulator according to the ignition module requirement.

A: Recommended propellers include 27x10, 26x12, 28x12 and 28x10. Final propeller selection should match aircraft size, weight, flight style, altitude and safe RPM limits.

A: The product page highlights balanced propeller as a key feature, but final included propeller contents should be confirmed before order.

A: The listed main engine weight is 2370g.

A: The listed exhaust weight is 280g and the listed ignition weight is 190g.

A: It is suitable for giant-scale RC airplanes, large sport aircraft, scale aircraft and aerobatic aircraft designed for a high-displacement gasoline engine.

A: This engine is best suited for experienced RC pilots or beginners working under expert supervision. Large gasoline engines require careful installation, fuel handling, ignition setup, tuning and propeller safety.

A: Yes, it may be used in petrol-powered fixed-wing UAV prototype projects if the airframe, vibration isolation, fuel system, propeller, cooling, ignition and safety procedures are professionally engineered.

A: Typical required items include suitable propeller, fuel tank, fuel tubing, fuel filter, ignition battery, switch harness, throttle linkage, engine mount, starter equipment, field tools and correct gasoline/oil mix.

A: Propeller balancing helps reduce vibration, protects the engine and airframe, improves reliability and supports smoother operation during flight.

A: Maintenance should include checking propeller bolts, engine mounting bolts, exhaust bolts, spark plug, ignition wiring, fuel lines, fuel filter, throttle linkage, tuning status and general engine cleanliness.

A: Operators should follow propeller safety, fuel safety, fire safety, secure mounting, safe starting procedure, safe tuning practice and field operation rules. Never stand in the propeller arc during operation.

A: Warranty support generally covers manufacturing defects under approved use and normal operating conditions. Damage from incorrect fuel mix, poor tuning, overheating, propeller strike, crash impact, dirt ingestion, water exposure or unauthorized modification may not be covered.
