Heinkel He 3


The He 3 which followed later in 1923 was a small cantilever monoplane with a monocoque wooden fuselage, accommodation for a crew of three, and powered by a 75-hp Siemens-Halske radial. Its most interesting features were the easily-removable wings and an undercarriage which allowed the quick interchange of landing wheels and floats. It is not known how many He 3s were built, but the type was used mostly for exhibition and sporting purposes. One, with a 100-hp Siemens engine, was first in its class at the 1923 Gothenburg seaplane exhibition.
