I applaud your efforts, I've often thought the Quail was a design worth reviving.

I'll add your efforts to my VW Powered Homebuilts Rant.

I'm a little concerned about your empty weight, and it's effect on performance. You're about 200 pounds heavier than a well built Teenie. Some of that can be alleviated with more wing, but you don't list a wingspan, chord, or area, so there is no way to gauge if your stall speed has any credence. A teenie stalls - as well you know - a lot faster than you're claiming, with a 18 ft wing, a 40 inch chord, and less weight. The maximum coefficient of lift for a Clark Y is not a whole lot higher than that for Teenie airfoil (I forget what exact section it is, but it's a 15% 4000 series section). The only way you'll make those stall numbers is with a substantial span increase over the Teenie.

More detail is needed to give your labor of love a fair evaluation.

Good luck building, and flying, and should your numbers prove out, I'll be the first to sing your praises. The configuration you've chosen is one I like a lot, and have thought about designing my own airplane around.
