Default RE: DLE 30 & Plastic Props

ORIGINAL: davidhand

I am a nubie to gas engines and have a DLE 30 on which I have mounted a glass filled Master Airscrew propellor. I have been told by an experienced club member that plastic prop not good on a gas engine as it could transfer shock load to the crankshaft in the event of a rough landing that could be damaging. While I respect the advise of the member who gave me this information I am curious to hear of other views on this subject.

This is a problem with any large engine running any large prop thats not wood. Wood props are brittle in the rotation diecrtion which if they strike is good thing.
Plastic is too tough.
Even Carbon is really only for very experienced and wealthy pilots

I'll stick to wood for now.

But this all revolves (pun intended) around proper landing. If you can land its not really an issue.
