Thanks for your responses, folks! I've been thinking a lot more about this project, and I will be writing things down and doing some more drawings. Here's what I'd like to do to check/refine the aerodynamics:
Build a scale wind tunnel! For the 1/24th scale of this model, it would be pretty easy --and I can even use my belt sander (upside down on the floor of the tunnel) to mimic the moving roadway, and to spin the tires...
Is this something I can find on Instructables? How would I make a scale sized smoke trail device?
