Of course, this is a very general question. If you can give detailed answers, even better. I've read that many Japanese planes used an airfoil similar/identical to the NACA 2200 series - but I don't remember where I read it and I don't remember which planes were mentioned.

I also think that I've seen a couple of documents that mentioned the airfoil type, but again I can't find them. http://forums.ubi.com/groupee_common/emoticons/icon_mad.gif

So whoever can shed a bit of light on the issue, please do so.

It is true that most high performace airfoils will be symetrical, that is the top being same profile as the bottom, where lift is equitable. on Gliders, the Eppler designs {{Eppler 210 with slight undercamber for example}} ( which he developed many foils ) develops the most lift. and of course a " flat " bottom air foil for the heavy lifter/s bomber etc. Never heard of NACA " 2200 series " though I have seen listing like : NACA 2412 and NACA 2418 . You can go here : //www.davincitechnologies.com
and stroll thru the list and down load the foils but as to specifics you may have to go to the manugactures spec/build sheet to match 'em up. I built several of my own foil designs for Radio control sail planes but Martin Eppler's 210 pretty much got to it way before I did... and you can pretty much agree that a symmetrical foil is pretty hard to beat for pure acrobatics or on the " edge" as most fighters need to be and some with dihedral like the F-4's and the WWII F4U gull wing....awesome performance indeed !!!! Never heard what the IJN or IJA used for foils but would bet they are pretty symmetrical eh?

JtD, David Lednicer's list has many of them: Incomplete Guide to Airfoil Usage (http://www.ae.illinois.edu/m-selig/ads/aircraft.html)

Hey, that's great already. I guess the aerodynamic performance for some of these will be hard to find, but at least now I know what to look out for. Thanks!
