The FlySpark AeroEngine-730 Four-Cylinder Gasoline UAV Engine is a high-power 730cc propulsion system designed for large industrial UAV platforms that require strong thrust, long-endurance performance, and reliable field operation.

With a four-cylinder, two-stroke, air-cooled engine architecture, the AeroEngine-730 delivers powerful performance for heavy-lift UAVs, large fixed-wing aircraft, hybrid VTOL platforms, cargo UAVs, and professional industrial drone systems.

The engine provides up to 63.5 hp / 47.3 kW power output and supports UAV platforms up to 270 kg MTOW, making it suitable for demanding professional applications where high propulsion power and dependable operation are required.

Its air-cooled design reduces system complexity, while the solid-state magneto ignition system helps provide stable combustion and lower maintenance requirements. The engine supports push and pull propeller configurations, giving UAV manufacturers and integrators flexibility for different airframe designs.

The FlySpark AeroEngine-730 can also be configured with optional EFI fuel injection, electric starter, and generator system depending on project requirements. This makes it suitable for UAV platforms that need engine power as well as continuous electrical support for avionics, sensors, and mission equipment.
