MAN! You have done your delta homework! With the heavier gear, it will come out at 25 ozs or so, which should still be light enough. I'm following the LS planform, and I thought you might like to see a naked DD type airframe. The fins are basically a hatch cover for the 600 MAH battery, and I will fiberglass the fins to make them nice and stiff. The big servos will be laid down flat, I think, to help tuck them in. The airfoil is 1" thick at it's highest point, which works out to 5%. I'm going to see if this thing can be ready for tomorrow. There is a minimum of trick or fancy techniques that burn up time, that's the beauty of these deltas.
