About Us


REINERSTEMME.aero GmbH (RS.aero) seizes the opportunities offered by the new generation of electric engines for light aircraft: CO2-free, quiet and cost-effective. They fulfil our urgent goals in environmental and climate protection.

RS.aero relies on a team and a partner network that has been sucessfully turning research and innovation into sophisticated aircraft products for many years.

Our first aircraft, the RS elfin 20.e, is a remarkable combination of a two-seater electro-hybrid powered aircraft for touring flights, however with top competitiveness in gliding. This combination opens up a global market beyond classical borders.

The electric flight duration will be between one and three hours and benefits of the latest battery technology. It will be launched on the market with its maiden flight in 2021.

The second aircraft will be the RS 100 WHISPER. It is based on the RS elfin 20.e technology, and is a reconnaissance aircraft for regional environmental, commercial and governmental missions. It will be launched in 2022 using profound advances in battery development, combined with high-quality aerodynamics. The electric flight in 2025 will be up to 5 hours – CO2-free, quiet and with a minimum of the operating costs in comparison to conventional systems. We shall publish the RS 100 WHISPER in 2021.
