Engineer Alfred Marcel Joachimczyk in 1910, at the Deutsche Flugmaschinenbau Gesellschaft at Berlin-Rummelsberg, designed the “Maikäfer” (“Beetle”), with the construction being completed in the spring of 1911. After several trials and errors, the craft finally flew for 19 minutes, but was seriously damaged in a later flight. The Beetle was a two-seat aircraft with wings in a tandem arrangement, constructed of wood, steel tubes, and canvas. The landing gear consisted of wide wheels, a tail wheel, skids, and at the front of the hull were additional runners. The engine drove two pusher, counter-rotating propellers.

Designed by Willi Schultze-Herfort and built in Rummelsberg, near Berlin, by Deutsche Flugmaschinenbau Gesellschaft (D.F.G) in 1910 the Argus-powered monoplane as flown by Alfred Behrend at the 1. Internationale Flugwoche, 10-16 May 1910 in Johannisthal.
