1/10 RC german SdKfz 9 Famo heavy artillery tractor

Fully 3D printable german SdKfz 9 Famo artillery tractor 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.

The Sd.Kfz. 9 was designed to have a towing capacity of 28 tonnes.

All were equipped with a winch, mounted in the middle of the vehicle, just under the cargo platform.
