While HTV is busy working on new content, check out some of our old videos from a few years back. This Airfoil video was first published back in October 2013.
This video explains what an airfoil is, the parts of an airfoil and the differences between symmetrical and asymmetrical airfoils with emphasis on the Robinson R22 Helicopter.
