Paul, is anyone working on a one rotor . Suitable for LSA applications
other than Richard.
Anyone contemplating a 16x one rotor.

Clifton,
Originally I had planned a four place a/c with a two rotor to replace a
150hp O-320. I read about single rotors but never paid too much attention.
As needs and desires have changed, I am now working towards a 120hp single
rotor p-port and aiming for the weight to match an 0-200 for an extreme
STOL. Hopefully by the time I'm ready for the engine someone will have done
all the hard (smart guy) work.

    I have a single rotor 13B built by the late Lou Ross.  It has his reduction drive 3.17:1 turning a 68 inch IVO magnum electrically adjustable prop.  Custom exhaust with muffler, and Ellison throttle body.  It has run, probably 8 hours or so, and by Lou's calculations made around 120 hp at 6000 rpm.  Probably a few months of installation remaining before I attempt to start it in my Q200.

With a 3.17:1 PSRU it may well indeed produce 120 HP or more. Lou was a very good engineer.
