Rather than a traditional steel  SAE prop flange the new gear box would
    have this hub.

    The prop hub and shaft flange are combined.

    Saves weight and cost and the pitch is ground adjustable.

    Paul,

    What length of prop would this work with, and any prop manufacture in mind ?

    Warp Drive and Sensinich and an out fit in Oz makes compatible blades.
    Th Oz company name escapes me at the moment.
Bolly props I think.

The blade hubs are becoming a world wide standard.

Maximum length I have no idea. Probably the material is a factor.
I would do extensive testing.
