I hafta agree with Rick N. on the Powerfin.

I also run a 3-blade, 72 inch Powerfin behind my 912ul.

Although I enjoy the performance its wide blades provide, and its ease

of adjustment, it is not as robust as a Warp.

I had the oil cap go thru the prop (my fault - failed to ensure it was

secure before flying).  Put a big enough gash in the leading edge to as

render that blade unusable.  Had to spring $140 for a new blade.
