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 0320 . 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 0320s & 0360 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 .
