Fokker DRI1/28
Probably the most built aircraft from WW1. There are so many versions possible. Nice kit for little money, but requires some extra work.
Background information:
The Fokker Dr.I, flown by legendary flying ace Manfred von Richthofen, better known as the Red Baron, made history in World War I. This agile aircraft achieved high climb speeds and was capable of reaching a top speed of 193 km/h thanks to its Oberusel radial engine.
