Hi.

Has anyone used these ? If so, what are your opinions?.

Thinking of using a pair of these on 815kv brushless out runners.

Here is a library photo.

Personally I think the rubber coupling is far to short and they act more like a solid coupling , best bet is to go for the Mobile Marine Models couplings, far superior...

... or MMBs which are very much like MMM's.

ukmike...it really depends on the application 

1. the coupling you display is designed to provide a resilience in motion between components in shaft rotation....not necessarily a shaft alignment issue
2. an example of the coupling design concept......could be to eliminate the impulsive characteristics of an internal combustion engine

For a high power electric application....best copy a typical coupling they use  .......Derek

            Extremely good couplings  --  used them on tugs with 100mm props (in kortz nozzles) and high torque motors
            between 3000 -6000 rpm for many years.
