The need to make a strong and light aerodynamic structure reminded us of a youth misspent building model airplanes. We made the duct walls of 1/16-inch balsa wood. With the grain vertical, it can easily flex to follow the required curves, but has good compressive strength. Start by supporting the back of the duct floor at the required height. We used masking tape to hold it in alignment from side to side.
