1/10 RC german 8,8cm Flak 37 Sfl self-propelled gun

Fully 3D printable german 8,8cm Flak 37 Sfl. self-propelled gun in scale 1/10.

The Sd.Kfz. 9 (also known as "Famo") was a German half-track that saw widespread use in World War II, and the heaviest half-track vehicle of any type built in quantity in Nazi Germany during the war years. Its main roles were as a prime mover for very heavy towed guns such as the 24 cm Kanone 3 and as a tank recovery vehicle. Approximately 2,500 were produced between 1938 and 1945.

Both tracks and wheels were used for steering. The steering system was set up so that shallow turns used only the wheels, but brakes would be applied to the tracks the further the steering wheel was turned.

A few models of this half-track were adapted to mount the infamous 88 mm FlaK 18 cannon in 1940. The vehicle was supposed to be used as a tank destroyer, picking enemies from the distance, behind the cover of allied units. Still, for a half-track, the crew were decently protected against small-arms fire.

The full name of the vehicle is: 8,8cm Flugzeugabwehrkanone 37 Selbstfahrlafette auf schwerer Zugkraftwagen 18t (8,8cm anti aircraft gun mod. 37 self-propelled carriage on 18t heavy tractor).
