I'm not sure of the thicknesses (12% vs. 15%) but it says right on Van's website that they use:
NACA 230 Series for all 2 seat RV's except the RV9A, which uses a Roncz and the RV10 which was a tailored airfoil of some sort.
I believe the RV3 had the 23012 and the others 4/6/7/8 use a 23013.5 as mentioned previously. A 230 series wing with 15% thickness is a pretty thick wing...
Anyway, I'm not the expert - but between what is on Van's website and what I have laying around here, that's the info I've got.
Cheers,
Stein

This is my question, which airfoil is used on the -10?

If it's a customized airfoil, there might not be a specific number for the entire thing. It could be a combination of airfoils from root to tip...I don't know - but I do know who does! Give a call out to Oregon.

It's not worth it to bother them.
I was surprised they didn't use the same airfoil as the -9 due to the success that they had with it.

But I think the bottom line is that the -9 airfoil was designed to aid in low speed characteristics and that was not a factor in the goals for the -10.

True but the -9 is still very fast for its HP.
Don't get me wrong, Van's did a great job on the -10 and I'm not second guessing them in any way. Just trying to understand their decision making process.
