Mini-Bee: an eVTOL hybrid aircraft
Mini-Bee is a piloted multicopter designed for two people. Its multiple rotors allow vertical takeoff and landing, supported by a hybrid system using a general aviation engine to generate electricity during flight.
Technical Specifications
- Cruise speed: 170 km/h
- Range: 600 km
- MTOW: 700 kg
- Max power: 100 kW
- Capacity: 2 people

Versatile & Sustainable
Mini-Bee can be used for civil emergency missions such as air ambulance transport. With its compact VTOL capabilities, it is ideal for urban mobility, cargo delivery, or even personal transport in dense areas.
Our team uses advanced materials and hybrid electric propulsion for lower noise and reduced emissions. Extensive testing ensures Mini-Bee’s safety, performance, and ease of maintenance at low operating costs.
We believe Mini-Bee will transform air mobility with its simplicity, efficiency, and sustainability.
A Highly Collaborative Project
The project operates under a dedicated Lesser Open Source License, enabling cooperation between academic, industrial, and individual contributors via an open-innovation workflow and public wiki.
Some tasks may remain private, and proprietary elements can be integrated. Only interface works fall under the open source clause. Coordinated management ensures structure and progress.
All participants can reuse project outcomes technically or commercially, with default royalty terms defined.
An Open and Innovative Community
The Mini-Bee initiative fully embraces the principles of open innovation. By adopting a less restrictive open-source license, we foster close collaboration among various actors—universities, companies, and independent innovators. This approach democratizes the development of VTOL aviation and allows anyone to contribute to the evolution of Mini-Bee.
Transparency and Collaboration
The Mini-Bee project is designed to be transparent and collaborative. We actively share our progress and challenges on a public wiki, where contributors can follow developments and participate in discussions. This openness ensures that the project benefits from diverse perspectives and collective expertise, accelerating innovation.
Coordinated Contribution Management
The project is carefully coordinated to integrate diverse contributions while meeting safety and performance requirements. Each task is clearly defined and assigned, ensuring the project moves forward in a synchronized and goal-oriented way.
Contribution Use and Protection
While the core of the project is open source, some contributions may remain private or be protected by other forms of intellectual property. This allows flexibility for participants while safeguarding important innovations that may require additional protection.
Commercial and Technical Opportunities
Participants are free to use the results of their contributions for commercial or technical purposes, following a fair benefit-sharing model. This encourages innovation and commercialization while supporting the broader Mini-Bee ecosystem.
We invite all aviation and technology enthusiasts to join this exciting journey. To learn how you can contribute or to follow our progress, visit our wiki or contact us directly. Together, we can redefine the boundaries of aviation and shape the future of urban air mobility.
