Testing the Sensenich 3-blade composite propeller on the Rotax 912 ULS on a Zenith STOL CH 701

Here we install and test Sensenich Propellers' new three-blade ground adjustable composite prop for the Rotax 912 engine. As you can see, this new hub uses pin gauge rods to set the prop pitch. The prop is 3B0R68C-0. We've been impressed with the ease of installation and setting the pitch, as well as the performance.
Each hollow composite blade weighs about 3 lbs., with nickel leading edge protection.

Is this prop available in a larger diameter?
The light weight of the prop is easier on both crank shafts (direct drive) and gear boxes. Is it available in a 72 inch diameter for the Rotax 912S? Because of the gear box on the Rotax 912 cruise rpm of the prop is 2140 rpm @ 5200 engine rpm. This prop looks very much like a Keiv prop in its shape and construction.
