Paul, Pardon my ignorance, but is there a web forum related to this
newsletter or are all of your discussions pushed to newsletter
recipients via email (e.g., the crashed/rebuilt P/S 215 thread I am
currently receiving)? Regards, Carrick

I Mr. Lamar,
I would like to subscribe to your newsletter. I don't bring much if
anything in the way of technical expertise but in the course of my
own initial research in selecting a powerplant for my
post-retirement homebuilt aircraft project, I have come to the
initial conclusion that a rotary engine is an excellent choice in
terms of its power to weight ratio and overall reliability. As I
pursue my goal of a rotary powered homebuilt, I will likely be
asking a lot of questions; I hope this forum is the place for
gaining the knowledge and insight I need.
Thanks and Best Regards, CB Cheney
Welcome on board. I agree with you.

In any event,
I would like to know if anyone is operating a single rotor 13B w/ EFI &
turbo (Richard Sohn maybe?) and if so, what Takeoff & Cruise HP ratings
are they getting? Also, are all aluminum rotor and side housings still
available for the 13B or Renesis (I see RotaryEngine.com Al side
housings but not so sure of rotor housings)? Haven't seen anything
specific on the Pettit, Atkins, Mazdatrix, Pineapple, and other sites.
Would like to know what the firewall forward ready to fly weight for
such a setup might be? My target would be a ~200lb (or less) setup as
described above with ~200 hp Takeoff and ~180 Cruise power. Is this a
Pipe Dream / Unicorn Hunt for a single rotor? Envisioned airframe is the
Just Aircraft Super STOL (not the soon to be debuted Stretch XL
version). Any insight you have would be greatly appreciated.

A single rotor with aluminium end housing (from Racing Beat) under 200
pounds and 120 HP
is doable at 7500 RPM with a 3.12 to one gear box and a P-port. NA
A NA p-port 2 rotor version would generate over 250 HP and weigh not
much more.
Russ McFarland's 650 HP turbo P-port time to climb engine in the works
weighs
220 pounds with Bell 47 gear box. It runs on alcohol.
