Paul,

here’s a scenerio,,,,flying along with a ringfeder [flex coupling] on
my prop as a PSRU…..at about  4500 engine rpm…prop turning say
2250….elastomeric starts to wear out and the prop speed begins to
drop…..I divert and land…..taxi in and stop…..from what  see at the
ringfeder site I need some more elastomers and a wrench to pull off
the plate and prop and replace the elastomers. Put the front
plate/prop back on and start back on the flight.

Elastomers are small and light enough to carry a couple sets with me
on the plane and take along on the flight so I can replace them when
needed

Is that too simple an explanation on what the ringfeder is doing for
me?

It is under size for the HP you are trying to put through it. Send us
some pictures of what you have.
