I've been lurking for a few weeks. Just bought a KR-1
project and I have a couple of questions. Has anyone
used Ashok Gopalarathnam's airfoil on a KR-1? Any
reason not to?

Happy Friday guys
Mr. Langford (alias Flinkdink, AKA long ranger), please straighten us
out on the above topic.
My KR2 plans have only 2 wing sections, both RAF48 - one is 48" chord
(for the centre section) and the other is 36" for the tip.
According to my plans, these are the final dimensions a

Unless I'm mistaken, you might be a while waiting for Mr. Langford
Ashok designed that airfoil specifically for the KR2S

Thank you - it has now finally sunk in that there is a bit more to the
2S than a fuselage stretch, I had better get the supplement.
Take care

Nor did I know that the 2S had a different airfoil. Where can I get that
supplement?

You 2S guys please adjust my thinking if I am wrong.
The 2S is not any different than the 2, just Stretched. Certainly not the
airfoil.
The new airfoil was designed for the 2S, but has been put on the 2.
The new airfoil is not a product of RR.
The new airfoil is a mod that you may choose to

That is what I thought and you are mostly correct Dan, but I gather from
Mark L that the wing plan form is also subtly different. (Tip sectio

The published wing area is greater for the S, so the win is clearly changed.

The 2
If you are still building the same kr2 wing planform you can still use
the WAFs but you need to raise the rear spar about 1 inch to reduce the
incidence at the fuselage.

The problem is there wasn't a 36" airfoil template you could use for the
tip...until.now. See the bo
