should be able to produce better speed numbers(210-230mph) and not sacrifice
much more in approach and stall speeds.

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 p

I don't know about the speed, but I can tell you that there was a considerable
amount of credible and documented (and flight-proven) study and research done
to arrive at the AS50xx-series of airfoils that are spec
Hi all, is there any noticeable speed difference between having AS5048 and
AS5046 at the root. Also, how do the stall speeds compare? I know it is
something quite difficult to quantify because no 2 aircrafts are the same.
Lastly, has anyone used thinner than 15%. Would thinner mean more speed?
