Lloyd, while I will admit the Bonanza wing is a very smooth platform when
kept within it's envelop
Please bear with me as this is a new computer and I'm having a little trouble
getting used to it. The question I have for anyone who would care te express
an opinion concerns the airfoil for a KR2S. The design I would like to use is
the one Roy Marsh developed for the KR2S prototype. It is a

Bob, I just plain wouldn't use a 23012, no matter how modified it was.
Although it was used on everything from Cherokees to Bonanzas, the stall

Which Cherokee used the 23012?
I've flown several airplanes that use 23012, none of which were threatening.
Aren't the flight characteristics of a wing nearly as dependent on aspect ratio,
geometric twist, wing loading, high-lift devices, stall strips and planform...to
name a few...as the s

After thinking about your post, I'm compelled to comment further. Understand
going in that I'm as amateur as one can be, so I don't know what I'm talking
about:
It was mentioned that Roy Marsh's son is an aero engineer and chose 23012 for
Roy's PURPOSE-BUILT KR2S speedster. The magazine art
I think you just finished saying the same thing I did. It's probably not
going to have a pleasant stall characteristic, and if you tune that out
through other geometry changes, you'll be throwing away the speed.
He's free to build it as he sees fit, but I hope it sees more time in the
air than Ro
If I am not mistaken, this is the same or nearly the same airfoil on my
Bonanza. While it is a great speed wingtrust me..when it
stalls, IT STALLS. If both wings are not absolutely identical you will see
one wing drop dramatically sooner than the other.
Great for a roller coas

Another case in point about this airfoil. It may or may not apply to the KR
but take it as just more information.
When we first bought the Bonanza, of course we wanted to explore it's flight
envelope. So, up we went one day and decided to try some stalls. Power

Gentelmen,
I think that old saying is applicable here, "If it aint broke, don't

Hum, I'm still trying to figure out the worthwhileness (what a word) of this
