As a kid I was fascinated by paper airplanes for a while, and I noticed then that the tube shaped paper airplanes were the ones that traveled the furthest, had the most stable flight, and followed the straightest path, out of all of the paper airplanes I tried. So, my question is whether anyone has used large straight air tubes or air channels for cars, aligned precisely in the direction of travel? I am not sure if a round tube or square tube would be best, but inside needs to be straight and smooth. Thank you.
