Default which airfoil?

I'm scaling up some 3 views of a curtiss jenny, and I'm wondering what airfoil to use on it. I'd like it to appear somewhat scale, which means undercamber. I can't find out what airfoil the original one used, and maybe it wouldn't fly so good on a model anyhow. Suggestions anyone?

Default RE: which airfoil?

The Jenny had an "Eiffel 6" airfoil but I couldn't find the co-ordinates. Another fellow was looking for them here but nobody responded. http://www.rcuniverse.com/forum/m_93.../tm.htm#935302

I would just use a Clark Y but that's not very scale-like. It'd fly well though.

If you don't mind the extra building and covering time to get the undercamber the Selig 4061 works great for slow speed. It may or may not be better than a Clark Y but it'll have some undercamber for the scale look.
