INF 50cc EFI Engine (PN: IF50FI, IF50FIALT, IF50FITS, IF50FIALTTS)

The INF 50cc EFI Engine is a high-performance, fuel-injected UAV propulsion system designed for Group 2 ~ Group 3 unmanned aircraft with a maximum take-off weight (MTOW) of approximately 25kg. Built with components from Desert Aircraft, a trusted U.S. engine manufacturer, this engine delivers reliable performance for defence, commercial, and ISR applications.

Key Features:

• 50cc Single-Cylinder Engine – Lightweight, CNC-machined for durability and high tolerance precision.
• INF Inject EFI System – Optimized fuel consumption, improved reliability, and real-time telemetry for enhanced mission performance.
• Electronic Engine Management – Integrated system for precise throttle control and monitoring. Engine health management and protections throughout missions. 
• Fuel Efficiency – Using INF Fuel Injection improves fuel efficiency up to 65% compared to traditional carburettor engines, extending range capabilities enormously. 
• Advanced Electronic Ignition – Using INF Ignite single cylinder ignition provides advanced ignition curves and RPM control as well as a unique safe-start protocol for low RPM starting and transition to full run mode. 
• Twin Spark capable – Available in a twin spark (IF50FITS, IF50FIALTTS) variant with dual independent ignition modules for redundancy during complex missions.

Integrated Starter/Alternator (PN: IF50FIALT)

The IF50FIALT model includes a 3-phase starter/alternator system, available in:

• 6s (24V) or 12s (48V) configurations
• Remote start capability for autonomous UAV operation
• In-flight power generation, delivering 200–350W at peak throttle (7000 RPM)
