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.

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.

I'll look when I get home tomorrow.
