Blender 1.1 - Beta Test (youtube.com)
Left Steer and Right Steer to turn top blade.
Break to turn Bottom Blade
Gas to kill simulation, warp speed.
All of the blades can make game unstable pretty quickly. It would need more time steps/physics steps in the simulation to be able to handle it. Not something I can do.
Beta Blender 1.1
Very large blender that blends cars
