IIRC, Roy Marsh's plane, the 'poster child' for the original KR-2S promo literature, used the 23012 airfoil, which some of the Beech and Taylorcraft aircraft have used. Per NACA airfoil nomenclature, that makes it an unreflexed 12% thickness airfoil.
I have no information on how Roy's plane performed other than I believe it was the basis for Rand Robinson's claim that the KR-2S was a 180 MPH airplane.
