[C320-list] Gori-Prop buyer question - Not a prop manufacturer debate

[Chris Holt]

So I see you're thinking on the same lines as I was Pat.
Does anybody actually have the 15 x 10 Gori 3 blade and can report that 
there are no problems with the 15 x 10?

Just out of curriosity, having an under pitched prop means that you can't 
obtain maximum torque before reaching max RPMs, correct?
