Taking advantage of having to haul out this year to replace the
cutlass bearing, I ordered a Flexofold
folding prop to replace the fixed factory prop.
There are so many options for folding props it is difficult to
differentiate them. I went with Flexofold mainly because most of the
C270 mailing list members who have folding props have Flexofolds and
speak well of them. So at least it was a known quantity.
The sizing of the prop seems to be one part science two parts art!
Doing a poll on the C270 list, the recommendations given by
Flexofold themselves vary widely from 13 to 16 inches with assorted
pitches. (When I have some time I'll summarize the numbers on the C270 site.)
After talking with Flexofold, I went with a 14x11 R-3 (that's 14
inches, pitch=11, Right handed, 3 blade).
Here are some photos with the blades open and closed:
Here is a short video of opening and closing the blades:
