We are an independent student team at TU Delft developing a solar-powered UAV capable of indefinite flight. We rapidly design, build, and test prototypes to validate our designs in the real world. As a small, highly connected team of motivated and skilled students, we are able to integrate novel solutions like relaxed static stability, and optimize the design across aerodynamic, structural and control disciplines.

The current prototype, Everloft 1, is in the final assembly and testing phase and will be capable of all-day flights in its final iteration.
