All this talk about 2.85 gear boxes, getting higher into the power curve,
improving cliumb performance, etc, is really interesting.  Since 3 of my 6
initial reasons for going rotary were reliability, I'm wondering what running
at these higher power levels is going to do in that regard.

 
Hi Marv,
 
I think it's extremely unlikely that anyone will have a catastrophic failure of a NA rotary below 8000 rpm.  Now if you turbo it, all bets are off.  This is one of the reasons I no longer run a turbo on the plane.  I can afford to blow the FD engine, and AAA will tow it back to my house. 
 
You are correct about wear though, but you have to decide what you want.  I want a toy, that makes people say "Holy S***" every time I take off.  Even if it "only" lasts 1000 hours before it wears out, that's 30 years of flying for me.  The symptoms of a worn out engine are pretty benign, so when the time comes, I just rebuild it.  
 
Cheers,
Rusty (anybody need a turbo?  anybody at all...  <g>)
