Chassy/hull and running gear with metal tracks as used for both the Flakpanzer Gepard and the Leopard A4. I have cleaned the tracks in a sonic bath and silicon oiled them, the gear sets have been cleaned and lubed with silicon oil too. Some surface corrosion is still visible on the steel shafts but its just cosmetic. Mechanically what is there in in good nick. I have fitted radio gear (not included) and had it running round my house to test. I picked this up with plans to 3D print new wheels and body but to be honest I have so many other projects to do I have decided to concentrate on my other projects instead. This would suit a 3D printing enthusiast wanting a cool project or a tank collector for parts or restoration. Any questions please do ask.
