About ALPHAFROG

ALPHAFROG is a German ultralight aircraft manufacturer. Its legal notice names exentra GmbH in Pfaffenhofen an der Ilm, Germany. The company's vision is that flying should be open to everyone, simple, affordable and free of needless barriers. It aims for as little bureaucracy as possible.

The ALPHAFROG fleet runs from light single-seaters in unregulated classes to a four-seat touring aircraft. The models are the G1, the BIRDY, the G2 and the eG4. The G1 can be set up with an online configurator, and the BIRDY and the G2 can be reserved.

The company wants to make flying safer through software support. It also builds on proven aircraft concepts. Every ALPHAFROG aircraft flies with the Exentra Flight System, which is software that detects hazards before they arise. The airframe is generously sized. The aircraft are also designed to carry a rescue system, which is part of the safety concept.

The aircraft use highly efficient powertrains, which the company says give noticeably lower operating costs. The design is modular, so the aircraft stay easy to maintain and upgrade. Modern materials and technology, such as full-carbon structures, keep the weight low.

ALPHAFROG also offers electric and hybrid drivetrains. The company says they make quiet, low-emission flight possible for more people.

Every design follows one principle: lighter, smarter and built for pilots who want freedom without barriers. The ambition is the same in every class. The company wants an aircraft that brings together quality, safety and the joy of flying. Its pages are available in English for international and US readers, in German and in French.
