I think you would be able to make a pod racer out of a digi-q, some lexan, plastic and mold, foam, 3.8 motors, wire, and wires with small plugs and female connectors to fit in. Like this!
[]-[] <-- Electric ducted fan units
\ / <-- The wires with plugs
[-] <-- Pod with digi-q PCB inside
The difference in motor speed would steer pod like the car. Wires with plug would have female connector in the motor. The wires would simply plug into the EDF's. Small pieces of lexan would make small wings on pod and engines.
