Hard Mount???

[Atwood, Mark]

	Question for all you vibration guru's out there.  I'm tired of
soft mounts.  Seriously.  

	 

	Has anyone RECENTLY, tried using a reasonably firm, or hard
mount on a pattern plane with a YS???   I know I know...my servo's will
take a beating, blah blah blah.  And I'm sure it's true to some extent.
But I have several sport planes with YS 1.20's hard mounted, they run
like tops, idle at 1300, ...they literally purrr...  And I've been
flying them for YEARS...and I mean 8 or 9, with no issues on servos,
airframe, etc.   

	 

	I'm just wondering if we've over played the soft game and
shredded a zillion headers in the process.    Now I know my sport planes
are all wood and therefore handle the vibration better...  But wouldn't
the newer Nomex construction planes handle it fairly well too?

	 

	Would the current firewalls hold up??   

	 

	Is there a happy medium?

	 

	I'm considering mounting a 1.60DZ on a Brio with simple rubber
washers for isolation ala a gator style mount.  It's virtually a hard
mount with minor "give".  

	 

	Thoughts???  Opinions??  I'm all ears...

	 

	-Mark
