Re: Angier's question about laminar flow improvements at the wing/aileron
interface.

Angier, I'm not an aero geek by training but I have read NASA's treatises on
their research on NLF airfoils and from what I could glean, it is very
doubtful that even a perfectly clean and polished Lancair wing will maintain
laminar flow as far back as the leading edges of the ailerons (the only NLF
airfoils on the airplane). In the real world, at least the one I fly in, you
will collect enough bug-guts on the leading edges - I often find them as far
back as 6 to 8 inches - so 100% laminar flow is unlikely.

Of course, the name of the game is "Experimental", but this one. IMHO, seems
like a lot of trouble for not much return.
