The year is 1953. Nazi Germany has used nanite technologies to create micro-reactors and electric turbines to power this vehicle. This technology caused a shift in the war. It kept the Germans in the lead with technology, one of the reasons why the war went on for so long. They retrofitted a lot of the old vehicles with this new technology. The vehicle was able to fly about 500 feet off the ground gave it a strategic advantage.
The model itself was pretty much straight forward , except the turbines were made from PVC pipe and aerator parts, and the frame is brass tubing.
