You guys sure don't give me much credit! Yes, I'm bringing my wings up to
stock KR2S length, so dire predictions of my demise might be premature...at
least due to WAF or spar failure. Besides my spars are beefier than most
anyway (for reasons I dare not go into). I said when I built my wings
Not to beat a dead horse here, but one thing I think someone is missing is
that though you increased the wing area, you are decreasing wing loading,
and I believe that in itself would be compensate for the shear and bending
moments mentioned earlier.

I know this has been noted before, but I will repeat it. The Diehl wing
skins are significantly longer than the stock wings, and there is no
"beefing" required, and I know of NO incidents attributed to the longer
wings. I have them and the wing span is 23'6".
Mark, you don't have to worry.

Time for a new air filter and I can't find it anywhere. It is for the
Revmaster 2100 with ram air. Hose clamp at each end.
Can anybody help?
Thanks,

Hey Guys,
Before you get carried away please remember that Mark Lankford was
flying with clipped wings and I don't believe that he is adding anything to the
designed length of the wings. He is just bring them to the original designed
length. I'm just happy he is making the needed repairs

You must be careful with wing extensions as they increase the bending moment
at the wing root significantly. Also consider the extra load it will put on
the wing attachment fittings.
Aren't the Diehl skin wings longer than the stock plan wings? Guess I could
look it
Just checked mine with a digital level and also got 2 on the right wing and 1.8
on the left. Is that close enough for KR work. Maybe I should consider aileron
trim. Naw, not until it flies.

Always use the plans for determining these things.
The example from the plans is correct, 5" up at
the tip, Virg

KR2 standard wing with RAF48 airfoil.
Dihedral at bottom of wing: 3.64 deg.
Dihedral at wing chord: 3.05 deg.
Dihedral at wing center: 2.93 deg.
Dihedral at top of wing: 2.21 deg.

Actually, the dihedral isn't measured from the bottom of the spar, generally
speaking. It's more of a centerline angle thing, so measuring off the
bottom of the spar isn't an accurate representation of the "real" dihedral.
The real dihedral isn't even as high as 3.7 degrees...it's a little low

Interesting to read about your wing extensions. I am wondering what
you are doing about the extra bending moment and shear they will create.
If my calculations are correct (assuming no increase in your AUW, 1200lbs)
Your Bending moment will go from 68,000 inch pounds to 93,500 inch
What is the degree of dihedral on the KR2?

That is interesting. I assumed that it I put a digital level on the stub
and set it to 0, then put it on the outboard wing, it would give me the
angle of dihedral. Surprise, I got 2. I never gave it any thought, since
it had already been set when I started on the project. No wonder, I wander
