Mine is being built from parts by Bruce Turrentine. BTW, there are a lot of factors involved in building
a Renesis for aircraft use that are not obvious. For instance, you can't take the manual transmission
version and stick an automatic counterweight on it
without a re-balance of the rotating assembly.

I'll be running an RD-1C 2.85 gear drive to take
advantage of the higher rpm powerband.  Just ordered
the prop and it was a challenge working out how to
get the same (or close) cruise rpm that I use now
and still have the extra power available for
'afterburner'.   Clark Lydic at Performance Props
was very helpful. I'll let you know how successful
we were  (or weren't)  I haven't got the bill yet but Bruce says he will
build them in the aircraft configuration for about
$5800.

PS:  My favorite part of the 2003 Sun 100 race was
my radio call to #28, the longeze that started in
front of me.  "Race 28,  race 29 passing high on the
outside".    That was just as much fun as winning!!!

Tracy,  can you give us the "poop" on how you got
your
hands on a Renesis engine and perhaps the cost?  I
may
need one of these engines to run over you at SnF 05!
 
See you at Lakeland with either a Vari Eze (0-200)
or
my new Long EZ (0-320).   Ron  --- Tracy Crook <lors01@msn.com> wrote:
