Development of the machine started in December 1909. It was powered by a 12 hp engine driving a two-bladed tractor propeller. The undercarriage was a tricycle construction with a strong skid in the middle of the front wheels. The characteristic wing – later the trademark of the Geest Möwe Eindecker types – was based on earlier work of Alois Wolfmüller. The machine was not tested as Wolfmüller realized that the machine would not reach the required speed to get into the air.
