Doug,
I measured the angle of the top longeron at the cockpit while the plane is in the
landing position, it is 14.5 degrees. That's a little steep in my mind. Three
point landing should not be a problem! I'm not sure what other Pietenpol's
measure with the large wheels. Prop clearance is 25" in the three point position.
I will have to measure the clearance in the level position.

between those two values.

NX18235 sits at about 12.5 degrees in the landing attitude. It seems to
3-point nicely at that angle.
I don't know the exact prop clearance but it is at least 9" when wheel
landing.

NX899JP sits at just under 13 degrees. I don't think you would want it any
steeper than that

4" would be about 11" forward of the seat back and bottom interesection if
your plane is built according to the long fuselage plans. Or about 7.5" if
the seat back is at a 15 degree angle as Ray built his Sky Scout. I imagine
it is somewhere between those two values.

Jack,
I have a aircraft design textbook (Daniel Raymer, if I remember right) and 13 degrees
recommended is what I remember from the section on cockpit ergonomics.
I'll look when I get home tomorrow.
