Kit includes 10 brightly marked aircraft.

The Hansa-Brandenburg D.I, also known as the KD (Kampf Doppeldecker) was a German fighter aircraft of World War I. Despite poor handling, it was built for Austria-Hungary, some aircraft serving to the end of the war.

The D.I entered service in Autumn 1916. Its unusual arrangement of interplane bracing gave rise to the nickname "Spider", while its poor handling gave rise to the less complementary nickname "the Coffin". The D.I was the standard fighter aircraft of the Luftfahrtruppen until mid 1917, being used by several Austro-Hungarian air aces such as Godwin Brumowski and Frank Linke-Crawford. Some Phönix built D.Is remained in use until the end of the war, being used briefly by the armed forces of The Republic of German Austria (Republik Deutschösterreich), where they were used to fight Yugoslav attacks on Klagenfurt in Carinthia.
