I have to disagree. My Deb floats like a dream and doesn't have a sharp stall. The only spad I've built that had a bad snap was the Dominator and I think it's the tail design and I probably had too much travel on my elevator. I was going to build another one and redesign the tail to look more like the Deb tail, but I haven't gotten around to that. If that's been your experience with them, that's your experience and I certainly can't disagree with that, but to me, the spads I have built have flown well and had decent flight characteristics. It's not hard to get a rounded leading edge either, but I do it more for looks than anything else. Not trying to argue because I'm sure you have a lot more flying experience than me, but I just haven't had a lot of bad luck with mine.
