To the Forum members-

I am not building or flying a Kitfox, but I was wondering if I could possibly get some information from you.

I am the moderator of a forum that is for builders and flyers of the Pietenpol Air Camper and specifically, Pietenpols that are powered by a Corvair engine. Many of our builders are moving away from the original Pietenpol FC-10 airfoil and using the Riblett 30-612 and 30-613.5 airfoils.

It is my understanding the the later model Kitfoxes use the Riblett 30-612 airfoil. Am I correct on that? My question and the purpose of the post is this-

for comparison purposes only and as a point of discussion on our forum, I was wondering what the recommended CG range is for that airfoil when used on a Kitfox? I am not looking to stir up the pot, so to speak, or get into a discussion. I am simply looking for that bit of information. Does the factory recommend a CG range? If not, how did you determine the range? What do you use for a range?

Any help and information is greatly appreciated. I hope that I am not butting in. I was just looking for some info from fellow builders, and want to say thanks in advance for any help that you might provide.
