DLE 430 Two-Cylinder Two-Stroke UAV Gasoline Engine

A: The DLE 430 is a two-cylinder two-stroke gasoline engine designed for unmanned aerial vehicles, heavy UAV propulsion, large aircraft prototypes and professional propulsion testing.

A: The listed import price is US$8,635 for the DLE 430 UAV Engine Standard Package. Final pricing may vary if installation support, propeller matching, generator planning, cooling layout review, workshop support or UAV prototype integration assistance is added.

A: The listed displacement is 430.8cc.

A: The DLE 430 is listed with 42HP output at 6800 RPM.

A: The listed maximum RPM is 7000 RPM.

A: The listed idle speed is 1000 RPM.

A: The listed static thrust reference is 110kg. Actual thrust depends on propeller, pitch, reduction setup, air density, tuning, fuel mix, cooling and airframe installation.

A: The listed bore is 70mm and the listed stroke is 56mm.

A: The listed theoretical compression ratio is 11:1 and the effective compression ratio is 6.5:1.

A: The listed speed reduction ratio is 2.55.

A: The listed spark plug type is 14mm DLE-8.

A: The listed spark plug gap is 0.6mm.

A: The product page lists a DLE self-priming carburetor.

A: The listed fuel reference is gasoline 93# / 97# with 2T FD full-synthesis oil.

A: The listed oil mixture ratio is 50:1.

A: The listed gearbox oil reference is 85W-140EP API-GL5 / GL6 / SAE 140 EP gear oil.

A: The DLE 430 uses a double-set DC capacitor discharge ignition system with 12V power supply and 5W per ignition piece reference.

A: Yes, it is listed with a permanent magnet generator producing 14.5V / 90W.

A: The listed starting motor current is 35A.

A: The listed rotation direction is clockwise.

A: The listed radiator system is fan cooling.

A: The listed main engine weight is 27kg, exhaust weight is 4.1kg and total reference weight is 32.25kg.

A: The listed recommended propeller is a 1.5m variable-pitch carbon-fiber propeller. Final propeller selection must be handled by a qualified integrator.

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

A: Yes, the product page specifically states that it can be used for unmanned aerial vehicles. Final suitability depends on airframe design, cooling, vibration isolation, propeller selection, gearbox setup, electrical integration, payload, fuel system and safe test procedures.

A: No. This is a high-power heavy UAV gasoline engine and should only be installed and operated by trained users, professional integrators or supervised engineering teams.

A: Electrical planning should cover 12V ignition supply, starter battery sizing for 35A current, generator output wiring, fuse/protection strategy, vibration-resistant connectors, grounding and safe cable routing.

A: Cooling planning should verify radiator fan airflow, ducting, heat rejection, engine bay ventilation, fuel-line heat protection and temperature monitoring during test runs.

A: Typical required items include suitable propeller, variable-pitch control system if used, fuel tank, fuel tubing, fuel filter, starter battery, ignition battery, wiring harness, switchgear, throttle linkage, engine mount, vibration isolation, gearbox oil, cooling layout and field tools.

A: Maintenance should include checking propeller hardware, pitch mechanism, engine mounting bolts, exhaust hardware, spark plugs, ignition wiring, starter wiring, generator output, fuel lines, fuel filter, carburetor tuning, gearbox oil, fan cooling system and general engine cleanliness.

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

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, gearbox oil misuse, wiring errors, generator overload, dirt ingestion, water exposure or unauthorized modification may not be covered.
