The classic Clark Y airfoil and its variants like the YH are probably the most used and most studied airfoils in light aviation. This thread on the Clark Y-equipped https://www.homebuiltairplanes.com/...mics-new-technology/12165-davis-da-2-lsa.html got me thinking more about this airfoil's desirable characteristics for light aircraft: decent lift/drag, docile stall behavior, flat bottom facilitating easier wing construction and rigging.
What are some alternative airfoils that share these same characteristics (decent lift/drag, docile stall behavior, flat bottom) but offer advantages over the Clark Y? I'd also be interested in any thoughts on the "fat" variations on the Clark Y like the Clark YM15 and YM18 as I am interested in both decent speed and short-field operations without flaps and attracted by the structural benefits of thicker wings.
Cheers,
Matthew
