Hello,
Here's test flight with my 120" Don Smith Corsair and Moki 250. The prop is a 32" "solo prop" from CARF models with carbon blades. The pitch is set to about 23" calculated from the blade angle at a given distance from the center. It revs on the ground 3940 rpm and unloads in the air in a shallow dive to 5940 rpm.

Hope it works, you'll see wing folding in the end
