The FlySpark AeroEngine-170 EFI Twin-Cylinder Gasoline UAV Engine is a professional 170cc electronic fuel injection propulsion system designed for medium and large industrial UAV platforms that require stable power output, efficient fuel control, and reliable long-endurance operation.

Built with an advanced EFI fuel injection system, the AeroEngine-170 EFI provides automatic fuel delivery and closed-loop pressure control for consistent combustion across changing altitude, temperature, and flight conditions. Compared to traditional carbureted engines, the EFI system improves fuel stability, throttle response, and operational reliability for professional UAV applications.

With up to 17.5 HP output at 8,500 RPM, 170cc displacement, and a lightweight 4.1 kg engine body with air intake, the FlySpark AeroEngine-170 EFI delivers strong power-to-weight performance for fixed-wing UAVs, hybrid VTOL systems, industrial mapping drones, inspection platforms, and long-range monitoring aircraft.

The engine supports real-time engine telemetry through RS232 protocol, allowing integration with advanced autopilot systems for monitoring fuel status, RPM, temperature, and engine health. This makes it suitable for professional UAV integrators and manufacturers who need better engine visibility during long-duration missions.
