<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>
