Remember, aerodynamic forces vary as the square of the velocity.
By increasing speed, from, say 55-mph, to 80-mph, aero forces, stresses, and strains will increase by more than twice! Perhaps requiring shorter spans between supports.
He said 2 or 3mm abs thickness. Aluminum sheets are really wobbly. Worse than abs. I was at home depot checking out different materials. Steel was solid, but geez I didn’t realize it was that heavy!!!! No possibly way I could do a steel underbelly
