Aviatik D.III

Preliminary note: At first we thought that we got the scale wrong, but after double checking or even triple checking it, we realized that it was that long.

The Aviatik D.III was a prototype German biplane fighter that flew for the first time on November 1917 and became the basis for the subsequent Aviatik D.IV and D.V models.

Initially it was powered by a 195hp Benz Bz IIIbo gearless engine and was armed with the usual pair of LMG 08/15 machine guns.
After some testing performed at Adlershof during February 1918, some modifications were performed as they were requested by the Idflieg. In April, a second prototype, this time powered by a Benz Bz IIIbm, flew, even if the first variant (powered by the Bz IIIbo engine) was already in production. However, due to some delays and the armistice, none of them completed and it never went beyond the prototype stage.
