hehe, I meant aerodynamically speaking...

This is probably not a nice thing to say, but... I hate ARF's. They take almost as long as a kit to build and I am never satisfied with the finished product.
I know how to CAD and I found a guy willing to laser cut my parts. Airfoil choice is kinda difficult. I have a friend that has a Masters in Aero that helps me some, but I don't like to bother him too much. (not that he'd mind, I just dont't want to wear out my welcome.) And I like to be able to talk intelligently with him. (not look like a dumb***) I was wondering what kind of experiences people have had with blending airfoils and how necessary it is in the model world.

So I went about it in reverse? [X(] That's typical for me.

I am designing an ME 329. It's a flying wing with two pushers that was in development by the germans at the of WW2. Is there a benefit to a blended airfoil in a case like this? Or should I just go with a fully symmetrical airfoil. (it will be powered by .30 to .50 glow four-strokes) pics at http://www.luft46.com/mess/me329.html
