Hello,
I want to say something about it.
The Antoinette had not a Clark Y profile, not the original and not the replica.
Before the World War I there was no Clark Y wing, <span class="hps">developed</span> <span class="hps">1922.
</span>The thickness of the ribs does have a large impact on the aerodynamic and Clark Y <span class="hps">is a</span> <span class="hps">profile</span> <span class="hps">that</span> <span class="hps">is ideal</span> <span class="hps">for all aircrafts.</span>

Greetings matz
