The above poster pretty much nailed it.

We have a 3-blade flex-o-fold and are very happy with it. Each prop type has advantages and disadvantages - ain't none of them perfect.

Re: Folding prop maintenance/reliability?

Every time this question comes up, someone (usually me!) points out that feathering props are inherently less efficient than a well designed folder. Their basic design requires that the blades have no twist in their shape, ie they are flat paddle-like shapes, and this is by its nature inefficient. The bottom line is that it takes more engine power to create a given amount of thrust; the most noticeable result is less fuel economy.

They do generate lots of thrust in reverse when stalled, and thus are good for backing up off of mud banks and generating "braking" forces.

The better folding three blade props have gotten much better about thrust in reverse, but are not as good as a feathering one.

As Weyalan said, each has its benefits.

Cheers,

Jim

Re: Folding prop maintenance/reliability?

After reading everything I definitely like the idea of the folding prop over the feathering for my needs, and the flex O fold looks to be fitting the bill. I definitely have a lot of research to do but you guys have given me a lot to think about and a good direction to look in. Thanks again

Re: Folding prop maintenance/reliability?

One of the big yachting magazines (Yachting Monthly) did a reasonably impartial and fairly comprehesive set of tests on a whole bunch of the major prop brands. You can find a link to it here
http://www.flexofold.com/upload_dir/...onthly_low.pdf

(N.B. Yes - that particular link is in the Flex-o-fold website, but since the flexofold did rather well in the tests, I guess they see it as a testimonial of some sort). It is interesting reading, for sure.
