Hi list.  I just joined recently.  I am considering rotary power for my RANS
S-16 (www.shekari.org).  I'm looking for a powerplant in the 130-140 hp
range.  Most of the rotary conversions I've read about are higher power than
that.  The S-16, for those not familiar, is a little smaller than an RV-6,
about 930 lb empty weight.  Factory recommended engine is the IO-240
Continental at 125 hp, although several examples have O-320s in them.

I talked to Bruce Turrentine, and he seemed more interested in the Renesis
and sort of discouraged me on the 13B citing parts availability.  I guess my
question for the list is, is there a good configuration for that horsepower
level, maybe the 12B or something else? I would plan on using Tracy's
reduction drive and engine controller.

The bare engine weight of the IO-240 is 240 pounds by the way.

Thanks,
