Brian, I think the 63000 series is a standard exponential curve symmetrical airfoil with the high point at 35%. The last digits describe the thickness percentage, therefore a 63010 has a 10% thickness. I use the foil on both wings and stabs and find it to have outstanding character for pattern.

Mine are not bipes but it doesn't really matter. I use 10% wing roots and have found I really like 9% at the tips. Coupled with my very narrow tip chords, thinner tips enhance a foil's ability to build a smaller LE radius there, critical to snaps and spins being done crisply with precision and character. For a bipe's wing, thinner foils buy little since the chords are usually smaller and LE radii even smaller than on monos. Yet another reason why bipes should work the current schedules better.....

For stabs, determining what thickness you need if you want servos burried, will drive thickness percent up to a point. I try to never use more than 12% tho. I've found that thicker % stabs tend to mush in pitch and I don't like them as much as thinner %. I will compromise a bit by increasing root chord some and keeping the % thickness unchanged, in order to drive thickness up for servos. One man's philosophy on design parameters, of course
