DLE-55cc Gasoline Engine with Electronic Ignition

A: The DLE-55 is a 55cc gasoline RC airplane engine designed for large-scale RC aircraft, giant-scale model airplanes, aerobatic aircraft, sport aircraft and scale aircraft.

A: The listed import price is US$821 for the DLE-55cc Gasoline Engine Standard Package. Final pricing may vary if installation support, propeller matching, workshop support or UAV prototype integration assistance is added.

A: The DLE-55 is listed with performance output of approximately 5.5 HP at 7500 RPM.

A: The DLE-55 is described as capable of reaching over 9000 RPM depending on propeller, tuning, fuel mix, altitude, air density and engine condition.

A: The listed idle speed is approximately 1350 RPM. Correct fuel mix, carburetor tuning and ignition setup are important for stable idle performance.

A: The listed thrust values are approximately 14.2kg at 100m altitude and 12.5kg at 1800m altitude. Real-world thrust depends on propeller, tuning, fuel, air density and installation.

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

A: The listed compression ratio is 7.6:1.

A: The listed engine weight is approximately 1350g.

A: The DLE-55 uses 2-cycle regular gasoline mixed with 2-stroke oil. The listed fuel mix range is 30:1 to 45:1 gasoline/oil depending on oil type and engine operating stage.

A: The DLE-55 uses a Walbro membrane pump carburetor with manual choke for reliable fuel delivery and starting support.

A: Yes, the DLE-55 uses CDI electronic ignition with automatic advancing ignition support for reliable spark timing and improved operation.

A: The listed spark plug reference is NGK CM6. Replacement plugs should match the DLE engine specification.

A: Suggested propellers include 22x8, 22x10, 23x8 and 23x10. Final propeller selection should match aircraft weight, flight style, altitude, engine break-in status and safe RPM limits.

A: A propeller is generally not included unless specifically mentioned in the final quotation. Confirm package contents before order.

A: The product page focuses on the DLE-55 gasoline engine and related engine details. Muffler and accessory inclusion should be confirmed in the final quotation before order.

A: Typical required items include propeller, fuel tank, fuel tubing, fuel filter, ignition battery, switch harness, throttle linkage, engine mount, fuel-safe hardware, starter equipment and field tools.

A: The DLE-55 is suitable for large-scale RC airplanes, giant-scale sport aircraft, aerobatic models and scale aircraft that are designed for a 55cc-class gasoline engine.

A: The DLE-55 is best suited for experienced RC pilots or beginners working under expert supervision. Large gasoline engines require correct setup, propeller safety, fuel handling, tuning and regular maintenance.

A: Yes, it can 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: The DLE-55 is widely used because it offers strong power output, reliable gasoline operation, practical installation characteristics and proven performance for large-scale RC aircraft.

A: Maintenance should include checking propeller bolts, engine mounting bolts, spark plug, ignition wiring, carburetor settings, fuel lines, fuel filter, throttle linkage, crankcase condition and general engine cleanliness.

A: Operators must follow propeller safety, fire safety, fuel handling rules, correct starting procedure, secure mounting, safe tuning practice and field operation guidelines. 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.
