<DIV><BR></DIV>
<DIV>Interesting Nat,</DIV>
<DIV> </DIV>
<DIV>For a tip chord that is around 10", thats' around 0.15" or around 5/32".
</DIV>
<DIV> </DIV>
<DIV>The present tip chord I use in my designs is around 6" therefore the TE
thickness would be around 3/32" at the tip of my ailerons and roughly 2X
that at the inboard end, which is pretty near what I used. Dumb luck or
empirical experience, take your pick</DIV>
<DIV> </DIV>
<DIV>thanks, that's good info</DIV>
