Why does everyone want everything in 3D which can be done way easier and look even better by just exploring your creative side.
Build a miniature pod racer with anything you can find. You can get the parts you need from sink drains, pvc pipes, parts from plastic models, wood, shoe laces, nuts, screws, broken household appliaces, electronics....anything you can think of.
After you have build your pod racer, you can rig it like a puppit with a wire on each pod and the cockpit and attach the wire using an eye-screw. After you rig it, you can film infront of a greenscreen or on an accual location (better) then digitaly remove the wires later or just use a thinner wire that blends in with your background.
