Sometimes even giant death-bots wanna shake tail out at the old roller rink. 'Specially on disco night.
About this creation
I was building these for another model, but they turned out way bigger than I wanted. Still, the idea turned out well, so I snapped a few pics for posterity before scrapping them.
Kinda reminds me of those urchins at the mall with the wheelie shoes.
The small gears are convenient thumbwheels. they spin the spiral gears.
Keep crankin, and the main road wheels spin down into position.
