DA50

The INF Inject DA50 is a precision-engineered 50cc single-cylinder EFI engine built for Group 2 and Group 3 unmanned aerial vehicles with MTOWs around 25kg. Developed with high-grade components from Desert Aircraft and integrated by Innoflight, the system is optimized for ISR, defense, and commercial UAV operations requiring extended endurance and advanced reliability. This lightweight, CNC-machined propulsion system offers refined performance across variable mission profiles, with integrated EFI technology drastically improving fuel efficiency—up to 65% over traditional carburetted engines.

Available in multiple variants, including twin-spark configurations and starter/alternator-equipped models, the DA50 delivers high-resilience ignition, remote start capability, and in-flight electrical power generation (up to 350W). Its INF Ignite ignition module ensures secure low-RPM start sequences, while real-time telemetry and precise throttle control are managed through an embedded electronic engine management system. With fully integrated EFI calibration and optional generator compatibility, the DA50 is a turnkey propulsion solution for autonomous missions demanding dependable thrust and system-level control.
