Which folding prop?

[Sail 'n Soar]

I need a folding prop to use with my Astroflight 020sensorless geared motor. Kv = 2567 vs 3000 for the Astro 020 sensored motor, so it turns a little slower. Output shaft diameter = 1/4 inch, 11 to 12 inch diameter props. I've been looking at the Master and APC folding props because the Graupners appear to require a smaller drive shaft.

Your thoughts and experiences?

The Graupners work fine with the appropriate collet adapter.
