    Tail airfoil references?

    David Lednicer's "The incomplete guide to airfoil usage." The Incomplete Guide to Airfoil Usage is a great reference for wing airfoils. Is there a similar list that shows the tail airfoils.

    I am particularly interested in tail airfoils for a fast, lightweight (sub 1400lb gross) plane capable of the +/-220mph range.

    10% chord airfoils appear to be popular, would there be any advantage to a slightly thinner section (6-8%?).

    Re: Tail airfoil references?

    I'd be interested in any opinions on the tail airfoils below.

    Re: Tail airfoil references?

    We had a discussion about tail airfoils, a few weeks ago. For my knowledge there is no "similar list" with tail airfoils. When you said thinner, I guess you thought about classical sections like NACA-0008, it might be better to try NACA 6x-xxx series like NACA 64 012 for example, it has lower Cd than NACA 0008, but in same time it's thicker, which is a very good idea from a structural point of view, not to mention, that it has max thickness at around 40% of chord, which is another advantage over NACA 4-series.

    Re: Tail airfoil references?

    The NACA 0010-64 appears to be rather similar to the NACA 0010-34 ragarding the position of max thickness around 40% anyway. The main difference appears to be the noticably sharper leading edge of the 34 series.
