About us

RS.aero is the continuation of Reiner Stemme’s previous aviation history.

The history
Dr. Reiner Stemme and his team bring a lifetime experience of designing aircraft to the RS.aero. Since the 1980’s they are well-known internationally for designing high-performance aircraft with unique technological features and capabilities – such as the legendary STEMME S10 glider or the 3-ton surveillance aircraft Q01.

 
Access to a global partner network

RS.aero relies on a highly skilled engineering network of long-time colleagues and partner companies. This global network enables the methodical and cost-effective development of aircraft platforms.

Thanks to close cooperation with research institutes, the latest technological findings are incorporated into aircraft development.

Furthermore RS.aero is conducting various research programs aiming at finding the most suitable sustainable aviation propulsion systems of the future.

Started with the elfin
The first development project of RS.aero was the innovative electric motor glider elfin, where elfin is a perfect high performance self-launching glider, as well as a long-range recreational cruiser with a panoramic side-by-side cockpit. The final development, production and marketing of the elfin aircraft was transfered to the sister company elfin.aero GmbH based on an exclusive licence agreement in 2024.

Focus now on the 5-ton aircratft platform RS.500

With the 3-ton aircraft platform Q01 and the Patroller drone, Reiner Stemme and his team have gotten the first experience with manned and unmanned utility aircraft for various commercial and governmental application purposes. The result is the development of the innovative RS.500 aircraft platform:
FULL DAY MISSIONS, COST SAVING, PAYLOAD FLEXIBILITY, CLIMATE NEUTRAL & ECO-FRIENDLY

Sustainability also in the community

Much more than a mere business case, RS.aero sees these activities as an obligation to society and future generations.
