Xs-1
I built a XS-1 a couple of months ago to be dropped from a B-29. I had a rocket motor in it, when dropped it didn't light and it landed in a field with stickers, ticks, and Poison Ivy, so it's still there. The B-29 and the profile XS-1 are my friends, the XS-1s have 13" wing if I remember correctly, very quick little things.
