"elastomerics" were the rage. "composites" were the rage. The combination of them must be better. "the end of metal fatigue!" EUREKA ! If you will notice in the history of even modern helicopters. some parts just work better with good ole ball bearings; as Chevy Chase said as 'Fletch'.. "come on guys, its all ball bearings these days"
Enstrom even has a ($25,000) mod to eliminate them problematic "lamiflex" bearings? (well? lets do the math,, i hear one lami=thousand bucks. they last how many years?,,, how many Enstroms fly how many hours/year?
Chevy was wrong, its not ball bearings guys,, its SALES ! we need the $$ ! (last time i worked on an A-star was about 1989 & the cost of the starflex was ? 19 thousand?---they still sellin' them today too.
i know,, i know,, as the bug would say "again, pokey has added nothing to this thread". BUT? i feel i have, so? i am all warm & buzzy an gonna fuzz off.
