Key Highlights

Why the SW800Pro fits high-speed unmanned flight programmes.

High Power Density

784 N from an 8.4 kg engine unit. A 9.5:1 bare-engine thrust-to-weight ratio leaves more of your mass budget for payload, fuel and structure.

Wide Speed Band

25,000 to 65,000 rpm gives fine-grained thrust modulation from idle to full power across the flight envelope.

Single-Command Start

One-key electronic start with a fully sequenced profile. The starter pops out in 0.8 s while the ECU handles glow, fuel and ramp automatically.

Standard Aviation Fuel

Aviation kerosene with 3–5% lubricant, widely available at civil airfields. Full-throttle flow 1,850 g/min.

Full Telemetry

RS-232 and RS-422 interfaces expose speed, EGT and status to your flight computer; the ECU retains one hour of data before any fault.

Serviceable Design

25-hour maintenance interval, a 12.5 kg shipping case and a complete accessory set delivered with every engine.

Applications

Civil and commercial domains within the manufacturer's stated scope of use.

High-Speed Unmanned Aircraft

Large unmanned platforms needing jet-class speed and altitude beyond piston or electric propulsion. The 80 kgf class suits airframes in the 40–80 kg MTOW band.

Firefighting & Emergency Response

Aerial firefighting and emergency-response platforms — an application explicitly covered by the manufacturer's scope of use.

Industrial Air & Surface Drying

Road-surface drying and industrial high-mass-flow air duties, also named in the manufacturer's scope of use.

Scope of Use & Export Compliance

The manufacturer specifies this engine for model-aircraft flight, competition, demonstration, firefighting and road-surface drying — entertainment and civil applications only. Modification for unlawful purposes, or resale to countries under national export restrictions, is prohibited.

Engines in the 80 kgf class fall under dual-use export control. International shipments require an end-user certificate (EUC) and an export licence under the regulations of the People's Republic of China; Sheng-Fang Technology assists buyers through the application process.

Every engine ships with a manufacturer's certificate of conformity and full shipping documentation. Accessory set: engine unit, ECU (V5), GSU, mounting frame, DB3 power plug, DB15 signal plug and 2 m fuel line.
