Unicorn EFI – Sustainable Redundant Injection System

We would like to present our new redundant and flex-fuel electronic fuel injection systems developed for ultralight aircrafts and drones. 

We officially launched during the Mondial de l’ULM at Blois in September 2024 with our injection systems.

Since then, our products have been homologated for use on Ultra Light aircrafts in France by the authorities (DSAC) in February 2025 (UC105i and UC105iS) and have been flying for hundreds of hours already.

Our focus on safety and sustainability has resulted in the most advanced engine management to date.

We offer levels of automatic redundancy never achieved before and we also incorporated flex-fuel technology allowing existing aircraft engines to run on bio ethanol fuels.

Our flex-fuel technology allows any fuel to be used and mixed in any proportion seamlessly. No restriction at all!

E85 bio ethanol fuel is available worldwide and outperforms every petrol-based fuel being in sustainability with over 78% reduction in CO2 and 90% fine particle emissions or in engine safety with its octane level of 107.

Embraer has been flying with pure ethanol for over 20 years successfully for thousands of hours while most engines allow MoGas which includes ethanol proving their compatibility with such fuels.

We believe Ethanol based fuel are the future and the best alternative to date to Avgas while offering the best ecological impact of all available fuels.

Unicorn Aviation is an innovative French company specializing in advanced solutions for the propulsion of light aircrafts and drones transferring technology and solutions from motorsport at the highest level. Our solutions are flight-proven and developed to increase safety, efficiency and environmental responsibility in general aviation.
