Another thing to keep in mind in relation to meeting the LSA performance
criteria is who, besides you, is going to know for sure what the stall
speed (or any other parameter) really is. If you say the stall speed is 51
mph, as long as that's plausible who's going to even give it a second
thought?
thanks, I agree with mark not to misuse our precious time!
my question is related to that I simply may want my bird (KR1) to be
light sport compliant. 51mph does it, 55 doesnt. but I plan mine to be
simple and light, so I guess it should be fine.

Hi I posted this a while back,
Can i assume that no one has used the formula to determine stall
speed? Not sure how to with the RAF48, no idea what the Coefficiant of
Lift is, although the "new" airfoil probably has it someplace, or what
to input with the density of air number. Anyone care to take

I went you these links and understand a bit better but I dont have the
Clmax curve for the RAF48 or the "new" wing (at least the latter must
be around someplace). BTW I have never heard of this being discussed
to consider an aircraft for LSA compliant, has anyone else? Anyway not
sure what to use f

Make sure the CG stays in range with the heavier weight. Expect
longer takeoff run and slower climb. Watch the sink rate on landing

I should have included this one too:

Google for "utility category aircraft", and
https://en.wikipedia.org/wiki/Load_factor_(aeronautics) is at the top.
Utility means 4G load factor, and Normal means 6G.

"You could also build it by the plans and consider it "utility category"."
What does that mean?

Sorry, we are looking at a KR2 that is partially built. Has fuselage, tail
and stabilizer built, no start on the wings yet.

Lots of folks have built KRs and simply placarded them at 1100 pounds or
more. There's
Is there a way to increase the useful load by 50 pounds? My wife and I
would fit, but we could not carry any fuel or baggage. lol

Is this question about an airplane being built, or already finished and
registered? KR2 or KR2S?
