Jack,
I think the 15 inch by something prop should be the right starting point in my case, but the only thing I am not certain is the difference in P-factor between the 15 inch vs 17 inch like yours. Did you had to add more right thrust on your setup? One more question, could you comment on the incidence on the stab and the wing, I mean did you had to do any adjustment?

No, I didn't modify the thrust angle nor the incidence, the plane flies perfectly out of the box and your setup isn't different enough to change that. Do me a favor and post your power setup (batteries, brand, C rating, motor, impedance, rpm/V, resistance, etc) and I'll run it through MotoCalc and post a side-by-side of mine to give you an idea of performance...
