Helihobby and Like90 both sell blades like these. They're flat bottom all the way through, but the root of the the mount is twisted to create the angle of attack. They require a much higher headspeed to get the heli off the ground, consequently making it much more stable. The only problem i've found so far, is that because the blades are designed with the root fixed, there really isn't any way to adjust tracking that I know of. It's not like you can bend the roots like the stock plastic ones because these are wood. So you system might be better if it works. I included some pics of my bird in it's work stage so you can see.
