DLE-170 Twin Gasoline Engine

A: The DLE-170 Twin Gasoline Engine is a 170cc horizontally opposed twin-cylinder gasoline engine designed for giant-scale RC aircraft, large sport aircraft, large aerobatic aircraft, scale models and professional aeromodelling projects.

A: The listed import price is £2,005 for the DLE-170 Twin 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 170cc, equal to approximately 10.37 cubic inches.

A: The DLE-170 is listed with output of 17.5 HP at 7500 RPM.

A: The listed RPM range is 1,100–7,500 RPM. Final RPM depends on propeller selection, fuel mix, tuning, air density and engine condition.

A: The listed bore is 52mm / 2.05 in and the listed stroke is 40mm / 1.57 in.

A: The listed engine weight is 4.11kg / 9.06 lb.

A: The engine uses horizontally opposed twin cylinders, which helps reduce vibration compared with many single-cylinder gasoline engine layouts.

A: The DLE-170 uses double V-type reed valves with bottom induction.

A: Yes, the package includes automatic electronic ignition.

A: Yes, mufflers are included with the package.

A: Yes, spark plugs are included.

A: Suggested propellers include 30x12 and 32x10. 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, ignition battery 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, large sport airplanes, large aerobatic models and scale aircraft designed for a 170cc-class 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, 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, 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 170cc twin-cylinder gasoline engine provides high power, strong thrust capability, low vibration and a high power-to-weight ratio 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.
