Something puzzles me. I found by chance, over the Internet, a 'ribs
generator' program, designed for radio-controlled models, wih more than a
thousand profiles available. You just enter the profile type, the chord of
the first rib, the chord of the last rib, and the number of ribs, and

I believe the RAF 48 in the plans are plotted from published coordinates, the
model RAF 48 may have been plotted by some curve fitting analog program.
I wanted to add more sq. Ft. to my KR w/o extending the wings so I plotted a
54" cord that is installed tight to the fus, the outer stub [48"] tra

I don't know about the thickness, but I can tell you that it sure does look

A "french curve" is a drafting template (you remember Drafting 101, where
you learned technical drawing, orthogonal drawing, lettering, etc.?) ;o)
Anyway, you use it to "fair in" curves between points. It has nothing to do
with Parisian women.
As Mark has noted many times, and documented in t

There's a PDF file of the RAF48 wing profiles at
http://www.krnet.org/as504x/raf48_templates.pdf . I did these a long time ago
for Dana, I think it was. They are CAD generated and accurate to the published
coordinates. But like Don said, the plans version work fine too. These are

The trouble is, what I get is different from the KR2 Scale 1 drawing.
The
KR2 profile is slightly thicker.
What the hell is wrong here?
Hey mon ami
There is not much wrong - your airplane flies great - no?
The RAF 48 (according to my software) is 14.96% at 30%Ch or 182.43mm f
