This goes back to the thing about many thinking the KRs are cruising with the
nose down.

If I can read my notes from testing I did some time ago my KR, with +3
degrees( or was it 3.5 degrees) AOA built in to the wing and 3 degree
washout, 1100 pound flight test weight, 150 mph cruise, flies with the
wing at +1.5 degree AOA. That would make the fuselage 2 degrees nose
down. This is almost in the "percent of error" of level flight. In all
in flight photos my KR seems too be flying level.

Early KR's flying at that speed and hundreds of pounds lighter might
possibility have a nose down attitude. At 180 MPH fly-by speed they
were certainly nose down. Like the pilots, the KR's have gotten heavier
over the years and that concern was self correcting. No one is going to
get it "exactly" right for their speed and flying weight so get it close
and go fly.
