Default prop size

Will a US-41 comfortably turn a 22 inch prop? If so, what is the max pitch, and if not, what is the largest prop you'd be comfortable with?

This is why I'm asking: I'm putting this engine on a 1/4 scale Vaillancourt Birddog, it is going to weigh probably between 18-22 pounds, and will only be flown scale (I promise, no torque rolls or knife edge). A scale diameter prop is a 22, and I plan to put a lot of detail on this plane, and the scale prop is part of it. I can lose the idea if it just won't work, maybe go to a Q52, although I already have the -41 (got a heck of a deal, brand new in box with the aluminum Pitts muffler)
