The INF Inject DA50 is a 50cc single-cylinder two-stroke UAV propulsion system engineered for Group 2 to Group 3 unmanned aircraft, delivering precise electronic fuel injection (EFI) for extended range and operational resilience. Designed by Innoflight with U.S.-manufactured Desert Aircraft components, the engine excels in defense and ISR environments where size, reliability, and efficiency directly impact mission success. Its integrated INF Inject EFI module optimizes combustion and telemetry, while the INF Ignite ignition system ensures safe-start sequences and advanced RPM control across flight regimes.
Available in multiple configurations—including twin spark for ignition redundancy and alternator-equipped models for onboard electrical generation—the DA50 provides remote start, in-flight restart, and continuous power up to 350W at peak throttle. Electronic engine management systems offer throttle precision and autonomous health monitoring, reducing maintenance loads in the field. With real-time system integration and high-efficiency performance (up to 65% improved fuel economy vs. carbureted engines), the DA50 delivers dependable propulsion for tactical UAVs operating in demanding defense scenarios.
