Woods!

I have used poplar a fair bit for ultrathin and narrow razer wheel bodies because it drills well and is strong. It is more dense, but when you use so little, the higher density doesn't hurt much. Over the years I have used a bunch of different species including bass wood and aspen and like those too. I have never made a car out of balsa - which is usually a good reason to do it !

My car Goat Slayer is 100% balsa with a 1/64 plywood top. Very fast car, but shipping it always made me nervous. It's been retired to Zeebzob USA.

Zeebzob, how in the world did you maintain the cant of the rear axle holes?? Balsa's like sponge--I would think all the weight back there would distort it.

That makes sense; no need to cant.
