Guys,
I've got a few newbie questions for the Stearman. First, mounting the top wing to the fuselage: I have both the top and bottom wing in alignment per the instructions, but the cabanes do not line up on the hardwood blocks along the fuselage. If I pull it into the desired position, it appears to start twisting the wings somewhat.
I'm not sure how to align this properly. Do I loosen the Phillips screws that mount the upper wing to the bottom wing? I'm thinking if I do this it will knock the top/bottom wing relationship out of alignment.

For some reason, I can't wrap my brain around how to do this.

Last question, I'm putting in an O.S. 1.20 fs (w/pump). What prop size do you all recommend? Composite or Wood?

Thanks for any input.
