Why I don't like folding props

A quick photo essay

They get sloppy

Then they beat themselves to death

Lastly they end up over pitching.

This example isn't excessive damages, it's about average.

Same thing is going to happen if you SLAM the transmission from forward to reverse without fully idling down. That ductile failure damage you see there is not normal or is damage from impact which only happens from abuse - someone has shifting without idling down to a reasonable rpm. I'll bet the farm on that.

My Martec folding prop has that kind of damage, although not as bad, and it was treated very gently. 24 years of service is what did it. My new prop is designed to prevent that happening.
