I am just not sure if I can get away with the scale airfoil on the model,my WS is 50" . Any thoughts? Im ready to start cutting Greg
Hey Greg! I went with a vanilla clark y. Works awesome. Takes off and flys very stable. I also was going to use the scenario you mentioned above. But it just seemed too thick for what I wanted to cut and I ended up not wanting the hassle. Its doable but I just felt more comfortable with the clark y.

I'll post some updated pics by Saturday (should have a rough coat of paint). Its taken apart right now for wbpu and is looking good. I had to sand all the darn latex paint off because it looked terrible and seemed too heavy. Let me know what you decide to go with.
