DLE-120 120cc Twin Gas Engine with Electronic Ignition and Mufflers

A: The DLE-120 is a 120cc opposed twin-cylinder gasoline RC airplane engine designed for giant-scale aircraft, large 3D aerobatic aircraft, scale aircraft, sport models and professional aeromodelling projects.

A: The listed import price is £1,185 for the DLE-120 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 120cc, approximately 7.3 cubic inches.

A: The DLE-120 is listed with output of approximately 12 HP at 7500 RPM.

A: The product page highlights 50 lb static thrust, making it suitable for demanding large-scale and 3D RC aircraft setups when correctly installed and tuned.

A: The DLE-120 uses an opposed twin-cylinder design, which helps reduce vibration and engine wear compared with many single-cylinder gasoline engines.

A: The listed bore and stroke are 47mm × 35mm.

A: A common DLE-120 package reference lists total weight at approximately 2781g / 6.13 lb, including the engine, mufflers, ignition module and accessories.

A: The engine-only weight is commonly listed around 2306g / 5.08 lb.

A: Yes, the package includes an electronic ignition module. Electronic ignition supports faster starting, smooth idling and strong throttle transition.

A: Yes, the DLE-120 package includes two matched aluminum mufflers.

A: Yes, two spark plugs are included for the twin-cylinder ignition system.

A: Yes, four 0.98" / 25mm standoffs are included according to the product package description.

A: The engine requires 87–93 octane unleaded gasoline mixed with 2-stroke oil. A 30:1 gasoline/oil mix is commonly specified for this engine.

A: Common ignition battery options include 4.8V–8.4V NiCd/NiMH, 6.6V LiFe or 2S LiPo depending on the ignition setup. Battery selection should follow ignition module requirements.

A: Suggested propellers include 26x10, 26x12, 27x10 and 28x10. 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 giant-scale RC aircraft, 3D aerobatic aircraft, large sport aircraft and scale aircraft designed for a 120cc-class twin gasoline engine.

A: It is best suited for experienced RC pilots or beginners working under expert supervision. Large 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: A 120cc twin-cylinder gasoline engine provides high thrust, smoother operation, reduced vibration and strong throttle behavior for very large RC aircraft and demanding 3D flight setups.

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.
