Well-done on this! If I may ask, what CNC mill are you using? I would expect the trailing edge to be paper-thin, especially if your airfoil profile is like this, and it's not a bad thing, necessarily (sharp trailing edges are good). Maybe a good thing to do would be to strengthen the trailing edge with some layers of fiberglass. Just a thought... keep up the good work!

It's a Taig mill. I think I need to strengthen the trailing edge a bit, but want to keep the design as simple as possible. I figure that the required strength of the blade material increases with the rotor diameter, and that if Dan and Hugh can use wood on their beasts, then I ought to be able to use wood for a smaller one. If I get a blade I like, I may make a bunch of them, as I have a bunch of small motors collecting dust. Rich Hagen
