That is not the prop that all the STOL guys like Peppard, Goza, Mackey etc are using. They are using the heavier 44 pound version by the Ohio Whirl Wind company and swear by it. It takes less than 1 minute to change the pitch on the heavier prop and it can be converted to a full constant speed by the factory if you so desire in the future. I do not know of any SC guys using the light prop. I think it leans toward the Rotax group, and I would be concerned about its durability in the larger SC engines especially 180hp and above. I don't think you will get the answers to your questions here cause I don't think anyone is using it. My opinion only.

Whirlwind aviation and whirlwind propellers.
2 deferent companies . Whirlwind propellers , which mine is {"GA200L 78" & 18lbs and 20 min. adjust time} and whirlwind aviation like Goza used ? [STOL 210G , &44 lbs and FAST adjust time], but they used to be one company and then split.
WW aviation makes certified props, mostly constant speeds but also make the VERY good ground adjustable STOL G210 , & WW propeller makes only exp. props none of which are constant speed so a lighter hub but can not be converted to a constant speed.
WW propeller does make props for 912s and all kinds of exp , airboats & even make blades for the M14P Russian radial , if they can make a blade that hold up to these beast I am not worried on my . If I understand it right WW propeller still makes the blades for WW aviation ? BUT my blades are NOT the same design as the STOL G210 that Goza and others like so well.
The GA200L 78 which I have is made for s & up 180hp . It is not as light as a Cato but is adjustable.
The 20 min. adjust time " is " a draw back for sure . BUT 26 lbs lighter than the faster adj. G210 by WW aviation is a big deal also for my plane.
I have a prop I can spin way up for take off and climb & in 20mins a prop I can cruse to Alaska from Kansas. Works for me!
I can not say how it compares to any of the props that every one is running on super cubs as I have not tried them, but would like to. It would be fun to do some pull tests with different props but the same plane .

I don't think that the time element of changing the pitch should greatly influence your decision of which prop to buy. Once you descide which blade angle you prefer, you will seldom change the pitch again. I do like my 200G and when testing to determine blade angle performance differences, I did make several flights in a short time span with blade angle changes. In a couple of hours I ran through the entire blade angle range 1/2 degree at a time. You will not do that with the 20 minute adjustment. But once you have determined which angle you like the best, the time element will not be important.
44lbs is definitely not the 18lbs it says on the website..... Is that 18lbs per blade? I thought these carbon props are supposed to be light? Also when it comes to the spinner is the 12" and 13" referring to the diameter or the length of the spinner?
Two different props. I have the 18 pounder. The 44 lb. one is twice as much $ and is heavier because of the hub, but is much easier to adjust. Spinner measurement is diameter.
