DLE-40 40cc Twin Gas Engine with Electronic Ignition and Muffler

A: The DLE-40 is a 40cc opposed twin-cylinder gasoline RC airplane engine designed for large-scale sport aircraft, scale models, aerobatic aircraft and professional aeromodelling projects.

A: The listed import price is A$1,510 for the DLE-40 Twin Gas 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 40cc, equal to approximately 2.45 cubic inches.

A: The DLE-40 Twin is commonly listed with output of approximately 4.8 HP at 8500 RPM. The product page also describes it as a five-horsepower class engine.

A: The listed RPM range is approximately 1500–8500 RPM. Final RPM depends on propeller selection, fuel mix, tuning, air density and engine condition.

A: The DLE-40 uses an opposed twin-cylinder design, which helps reduce vibration and improves smoothness compared with many single-cylinder gasoline engines.

A: The listed bore and stroke are 32mm × 25mm.

A: The listed total weight is approximately 1.5kg / 3.3lb including engine, mufflers, ignition module, spark plugs and mounting accessories.

A: The engine-only weight is approximately 1.17kg / 2.58lb.

A: Yes, the package includes an electronic ignition module for reliable spark timing, smoother starting and strong throttle transition.

A: Yes, the package includes two mufflers.

A: Yes, the package includes two spark plugs. NGK CM6 is the recommended replacement spark plug type.

A: Yes, engine standoffs are included according to the product page and common DLE-40 package references.

A: The DLE-40 requires unleaded gasoline mixed with suitable 2-stroke oil. A 30:1 gasoline/oil mix is commonly listed for this engine.

A: Common ignition battery options include 4.8–8.4V NiCd/NiMH, 6.6V LiFe or 2S LiPo depending on ignition-module compatibility. A regulator may be required with LiFe or LiPo packs depending on setup.

A: Suggested propellers include 19x8, 19x10, 20x8 and 20x10. Final propeller selection should match aircraft weight, altitude, flight style, break-in status and safe RPM range.

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

A: It is suitable for large-scale RC airplanes, sport aircraft, scale aircraft and aerobatic aircraft designed for a 40cc-class twin gasoline engine.

A: It is best suited for experienced RC pilots or beginners working under expert supervision. Twin gasoline engines require careful installation, fuel handling, ignition setup, propeller safety and regular maintenance.

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: Maintenance should include checking propeller bolts, engine mounting bolts, muffler bolts, spark plugs, 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 the propeller arc during operation.

A: Twin-cylinder gasoline engines can provide smoother operation, reduced vibration and refined throttle response for larger RC aircraft where smoothness and reliability are important.

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.
