He wanted a wing that would allow a smooth transition from hover to forward flight, and used the Airfoil Tools website to find and download the appropriate airfoil profile. To get around this, he designed the wings and their internal ribs to be printed in one continuously extruded line. It was printed with lightweight PLA, which can ooze badly when it stops extruding. used the process demonstrated in the video after the break to create the wing for his latest VTOL RC aircraft. If you’re moving beyond foam board wings, 3D printing is an excellent way to create an accurate airfoil, and provides us with an excellent guide to modeling wing sections for easy printing. The exact airfoil shape of a wing has a massive effect on the performance and efficiency of an aircraft and will be selected based on the intended flight envelope.
