As far as performance, I think it performs as well or probably better than the other props commonly used on the 912. It is difficult for me to judge the performance difference, however, because for me everything is new. New airplane, new engine, new prop, different pitot static system and completely new instrumentation, so I can’t honestly tell what to attribute any perceived changes in performance to, but it flies great.
Other than that, the craftsmanship is outstanding and prop is beautiful and it makes the airplane look awesome. So, what is not to like, except the price? It is a bit pricy but I would gladly spend the money to get a prop that wont tear up my engine and gear box. The cheaper heavier props, are in my opinion, penny wise and pound foolish now that we have this new option. Speaking of pennies that is my two cents on that issue.
I like the new Sensenich prop a lot.
The thing that I appreciate most is the fact that it is hollow carbon-fiber, therefore light weight, which means it has low inertia. I am told (by every ROTAX technician I talk to) that it is critical to the long term health of the 912 engine and gear box to use a prop that, at a minimum, meets the inertia specifications set forth by ROTAX. When it comes to comes to prop weight: the lower the better for the 912 and its gear box. And this new prop is unbelievably light.
Another improvement over the Warp and some others is the hub/blade-pitch adjustment system. With the Warp Drive there are simply two halves that clamp together with through bolts. The blade-pitch is adjusted by assembling the hub and blades and prior to tightening the clamping bolts, rotating the first blade by hand to the desired pitch. Then try to repeat the process with the other two blades attempting to get them all set to the same pitch. there is a lot of trial and error in the whole operation.
The new Sensenich system has indexed pins that drop into holes in the hub allowing you to adjust the pitch very easily with good accuracy.

Just checking to see how the project is coming along. Going to be able to fly this summer?

The rate would depend on speed and engine temps....but for the most part, I averaged 350 fpm at 78 mph. I could climb all the way at 500 fpm, but my CHT tended to climb. I would climb for awhile...level off and build speed and cool the engine...etc. But for the most part, I could have continuous climb at 350 fpm all the way up.

Sorry for the late reply.Busy at Can-Zac building my CH750. Completed in 6 or 7 weeks of 12 days. Can't quite keep track of time. The wife is OK with me being away, but the dog is starting to growl at me.

Still hoping to get over there and see your project soon. Dick Reeve would also like to see it because he's looking for something else to build now that his Legacy is flying.
The Sandbar shots are from Big Susitna, Yenta and Skwentna rivers. Lots of places to put down over there.
750 weighed 798 with and 0200 and 76" wood Sensenich prop.
