DLE-222 Flat Four Gasoline Engine

A: The DLE-222 Flat Four Gasoline Engine is a 222.5cc four-cylinder gasoline RC airplane engine designed for giant-scale aircraft, large sport aircraft, heavy aerobatic aircraft, scale models and professional aeromodelling projects.

A: The listed import price is CA$3,895 for the DLE-222 Flat Four 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 222.5cc, equal to approximately 13.6 cubic inches.

A: The DLE-222 is listed with output of 21.5HP at 7,500 RPM.

A: The listed RPM range is 1,000–7,500 RPM. Final RPM depends on propeller selection, fuel mix, tuning, air density and engine condition.

A: The listed bore is 45mm / 1.77 in and the listed stroke is 35mm / 1.38 in.

A: The listed engine weight is 5.61kg / 12.37 lb.

A: The engine provides 222.5cc displacement, 21.5HP output, a flat-four layout, dual carburetors, dual electronic ignition and a strong power-to-weight balance for large-airframe applications.

A: The flat-four architecture, balanced propeller setup and sealed bearing construction support smoother running when properly installed, tuned and balanced.

A: Yes, the package includes dual electronic ignition.

A: The product page lists two ignition batteries as required items. Battery selection should follow ignition-module voltage requirements and safe installation practice.

A: Yes, the package includes two mufflers.

A: Yes, the package includes four spark plugs.

A: Suggested propellers include 32x10, 32x12 and 34x10. Final propeller selection should match aircraft size, weight, flight style, altitude, break-in status and safe RPM limits.

A: A propeller should be treated as required separately unless specifically included in the final quotation. Confirm final package contents before order.

A: The package includes a 6-bolt prop hub for large-airframe propeller mounting.

A: The package includes machined aluminum standoffs, mount and mounting template.

A: The package includes a throttle arm extension.

A: The engine requires gasoline and suitable 2-stroke oil. Fuel/oil mixing and break-in should follow official DLE guidance and safe field procedures.

A: The product requires gasoline, oil, two ignition batteries and suitable propeller. Additional items may include fuel tank, fuel tubing, filter, switch harness, throttle linkage, starter equipment and field tools.

A: It is suitable for giant-scale RC aircraft, heavy sport airplanes, large aerobatic models and scale aircraft designed for a 222cc-class gasoline engine.

A: It is best suited for experienced RC pilots or beginners working under expert supervision. Large multi-cylinder 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: Maintenance should include checking propeller bolts, 6-bolt prop hub security, engine mounting bolts, muffler bolts, spark plugs, dual ignition wiring, fuel lines, fuel filter, throttle linkage, carburetor tuning and general engine cleanliness.

A: Operators should follow propeller safety, fuel safety, fire safety, controlled starting procedure, secure mounting, safe tuning practice and field operation rules. Never stand in front of or in line with the propeller while the engine is running.

A: A flat-four gasoline engine provides high power, smoother running, reduced vibration and refined throttle behavior for very large RC aircraft and demanding aeromodelling applications.

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, vibration damage, dirt ingestion, water exposure or unauthorized modification may not be covered.
