Big Lake Flight

7 posts in this topic

I finally got the 75 inch STOL Whirlwind Propeller installed and went for a flight Saturday evening.  The prop is incredibly smooth.  Was studying the issue of gear box chatter with the Rotax 912 ULS.  Minimum RMP is 1600.  This prop allows that for sure.  Very quiet.

It will take off as fast as you have nerve to pull back on the stick.  LOL.

Very nice Jeff.  What blade angle did you end up using? Sure does sound smooth.

Whirlwind advertises as quiet and smooth. That is exactly my experience.  Very happy with it.
