Also it is lighter than a metal one so different inertia.There are a lot of techniques and formulas for propeller design, in fact I did my aerospace engineering senior design project on a propeller design using blade element analysis, but then there's the real world. The calculated design is just a starting point for testing.
The fact that my new propeller has less pitch than the old one, but turns slower, pulls worse at low speed, but goes faster in level flight (in short, acts like a higher pitch prop) is interesting. I suspect that the thicker section and higher camber of the wood prop gives it a higher effective angle of attack, I.e. more effective pitch.
