Larry,
You are right on. Mark Lougheed did extensive CFD analysis of the wing
to come up with the optimum angle of attack and washout. The goal was
to be flying level at the higher cruise air speeds and to have as close
to the optimum elliptical lift distribution as possible to minimize drag.
Steve Eberhart
Mark is right. One of the things the original poster wasn't taking into
consideration is the pitching moment of the airfoil which tends to
rotate the wing down.

It is Friday after all, so Dana, Larry wants to know if you used a BLACK

RV-7A, the last parts kit shipped today. About another year to go. And
to be legit, I have played around with some KR parts.

Hi Bob, you too? My ride with Marty was one non-stop roller coaster
ride. He kept his hand about two inches over mine and kept dropping it
to stabilize the stick. That was my first KR ride. Not the way to gain
Ashok, the 15% and 16% airfoils are well suited for
use in single airfoil wings. I don't remember any discussions about
using the 18% in any configuration other than as a root airfoil tapering
to a 15% at the tip.

Building an RV-7A but I still have the original AS504x
decisions on their own. My AME
is also in my local EAA chapter and goes the extra mile to work with
problem cases.
Just a story where I was very impressed with my AME and the FAA. How
often do you hear that!

The horiz. Stab. Langford has on his KR incorporates all of the
modifications you have described short of the Armorall dispenser. His
plane just keeps adding up flying hours. Don't know if it is proving
anything but it seems to be well mannered. He has engineering drawings
for all of the airfoils used on his plane.

the AS5045 and AS5048
airfoils I put one of the panels out in the sun to speed up the drying
of the black lacquer finish. Very bad move. After only fifteen minutes
the heat had caused the blue styrofoam cores to swell. I was building
the panels to a +- .008" tolerance. The 1/8" th
could be excited into a buzzing condition where the
hinge were assuming something approaching a sine wave I would think it
could be even worse that the typical flutter scenario.

Wouldn't it be easier to just fly the panel over? :-) Larry and I will
be flying in in his RV-7.

N14SE, just a tail, wing and a lot of imagination
solution to what happens to the oil
from an oil leak. Cooling air exiting on the bottom of the plane
carries the oil out there. Updraft cooling, with exits in the low
pressure area just in front of the canopy, deposits the oil on the
canopy. Not good.

Can't wait to hear how the stability is with the Mole horns on the

ave a new list for flying KR's with the
AS504x airfoils. The number is growing. So far, the airfoils are
performing exactly as predicted.

six pack of that red stuff he likes :-) He only gets it if he flies to

m, try the standard RV metal prep practice:
1. Wash with Dawn dish washing detergent using a scotch brite pad to
scuff up the surface.
2. Thoroughly rinse with clear water.
3. Acid etch
4. Treat with alodine.
5. Prime with Napa self etching primer.
6. Paint with your paint of choice.

while the foam used for full
scale aircraft construction is OPEN cell. This is why you don't need to
micro model wings and you do full scale wings. Read the book, it
explains everything. Better yet, watch the video. Both can be ordered
from Wicks.

Plan in Chapter 11 and be sure to read Dr. Dean's article "Is Building
an Airplane Hazardous to your Health?" in Chapter 2. Also, Richard

A lot of good stuff here.

Because KR is more a state of mind than it is an airplane and like minds
