[NSRCA-discussion] New APC CF Props

[Dave Lockhart]

Carbon fiber is carbon fiber for the most part.  The distinction here is really between a CF prop that is formed from continuous strand and/or woven CF material in a mold vs an injection molded prop using chopped / milled CF (typically only a percentage of the material injected).  Injection molded is not as strong because of the shorter fibers and somewhat random orientation of the fibers……so more material (and weight) is needed to achieve the same strength.

 

Regards,

 

Dave

I'm ignorant of CF prop technology I guess. What's the difference in a carbon prop and a carbon fiber prop?

Jon C flew with one during practice in Orange County a week ago.  They aren't exactly carbon fiber, just using carbon instead of glass fiber, lighter than an APC, heavier than a true carbon prop.

Has anyone used any new APC 20.5x14 carbon fiber E props yet?  If so, what's the report?  They are certainly less expensive than the Falcon CF props.
