<div>Yes we do. The semi-scimitar design was a huge departure
from the "Normal". I heard from many "...what an ugly prop.....never
will use.... blah, blah, blah...." among other things. But performance
has silenced everyone.</div>

RE: Unusal Props</div>
<div><br>
</div>
True It might be that.<br>
I don't think I've ever seen a prop labeled as to how many blades.<br>
Interesting thought<br>
I like you're "tlarld"<br>
<br>
the prop markings are like this<br>
2<br>
12 O 5<br>
REV-UP<br>
<br>
with the "O" being the hole in the middle.<br>
<br>
It's times like this I wish the "list" could handle pictures. <G><br>
