Listees:
Joe Beyer Claims his craft stalls at 46 mph.
I ran air calck on the RAF48 airfoil @ 900# with the 78 sf wing area
claimed and sure enough got a clean power off stall 52 mph. I then put
51 as a given with a Lift Coef. of 1.5 and then 1.6 and got max.
allowable gross weights of 780#

I don't know that anybody can really "confirm" their stall speeds. It
sounds easy enough, but

I should also mention that there are several more KR stall speeds listed at
Orma's site at http://www.kr-2.aviation-mechanics.com/krinfo.htm . Mine
needs updating, now that I know a little more about the error in my airpseed
indicator, and there are a lot of KRs that aren't listed there, so
Gee Mark,
Did you ever consider that that "gritty overspray" may be energizing your
boundry layer, and delaying your stall?? I guess you won't know until it all
gets polished out, and you fall out of the sky at a higher speed. ,}

Well there's your answer then. Just pick up your KR2Sport
get yourself and
others in a possible jam.

What procedures are used to set GA aircraft???I thought our planes even
though Experimental are still GA airplanes Hell if you go off of RR
suggestions we would all still be building the old RAF48 airfoil.Nothing
wrong with this wing,but testing and research by our own KR family members
Bob, you are absolutley correct.
And the airspeeds are Indicated; True; Calibrated.

Come on guys!
Get serious! Anyone who is looking at an airspeed indicator to determine
when an airplane is going to stall needs to learn how to fly. While airspeed
(actually equivalent airspeed [EAS], look it up) can be helpful to measure
performance, when it comes down to flying the

That's true but I think you may have missed the point. I think some
