This aircraft, D-1433, which Friedrich Karl von Koenig-Warthausen named Kamerad, was a two-seater
low-wing monoplane with an empty weight of only 265 kilograms (580 lb), a top speed of 105 KM per hour (65 mph).
The aircraft, with its high aspect ratio and very low wing loading, would today be classified as an ultralight.
Daimler decided to have a new 20 Hp engine developed by its former chief engine-engineer Ferdinand Porsche.
The resulting 2 cylinder boxer motor was the first small aviation engine in its class, being both light and with low fuel consumption.
Koenig-Warthausen took off from Berlin Tempelhof Airport at midnight on 9 August 1928. After a long around the world journey, thick fog forced him to end his flight
in Hannover on 23 November 1929, 15 months after it began, having covered 20,000 miles (32,000 km) in 450 hours flying time.
