About the project
Two pilots.
One impossible idea.
No backup plan.
One impossible idea.
No backup plan.
Simon and Hugo met on the terrace of Birrfeld Aerodrome and discovered they'd independently arrived at the same audacious idea: electrify a 1934 Bücker Jungmann. That was 2023. They haven't looked back.
Birrfeld Aerodrome · 2024
Simon
Software Engineer and 3D Visualisation
Trained aerobatic flying at Langenthal Aerodrome in the 2010s. Flew a Pitts and Christen Eagle II. Came to Birrfeld with a crazy idea about electric propulsion — and found someone who'd had exactly the same one.
Hugo
Physician and Human Factors
Flew his CASA Bücker "The Red Ballerina" out of Langenthal. Obsessed with the intersection of historic aircraft and modern engineering. When the idea arrived, it felt less like invention and more like inevitability.
The project
Not a prototype.
A proof of concept for a generation.
A proof of concept for a generation.
This is Project 1 — the first in a series of experimental kit aircraft built under the umbrella of EAS, the Experimental Association Switzerland. The Bücker Jungmann is the test case: can a historic airframe be converted to electric propulsion cleanly, safely, and repeatably? If yes, the template exists for others. Different airframes. Different propulsion systems. The same spirit of obsessive, independent engineering.

For the engineers
EAS · Experimental Association Switzerland
The Bücker project operates under EAS — Experimental Association Switzerland — which provides the regulatory framework for experimental aircraft construction in Switzerland. Project 1 is deliberately designed as a template: a repeatable, documented process for converting historic kit airframes to alternative propulsion systems. The vision is a series — different aircraft, different power sources, same rigorous experimental methodology. If it works on a 1934 biplane, it works anywhere.
The vision
"One day soon, we will take off from Langenthal Airfield in almost silence. No engine noise. Just the hum of a propeller, the wind, the struts, and 90 years of aviation history — electrically propelled into the future."
— Simon & Hugo
