Dear Mr. Lamar

 I would much appreciate being included in the newsletter list. I am 78
 and am exploring the viability of building a homebuilt using the
 wankel etc. If one just reviews the physics of the of the
 reciprocaters versus the rotaries it would seemed the informed choice
 is the rotaries. I am not a conspiracy theorist in any sense but it
 would seem that those who manufacture internal combustion engines of
 any stripe using pistons that stop and start thousands of times a
 minute would be very quick to point out what ever they could, real or
 imagined, that would be detrimental to the rotaries. We are talking
 about protecting massive amounts of money committed to tooling and
 manufacturing and of course having to deal with patents etc. But I do
 think rotaries will eventually rule the day.

 I am an engineer by trade so the intended course of action is to mount
 the 13B on a test stand, and see what can be done. Certainly I will be
 going over plowed ground but new eyes, new ideas, and a new approach
 can't hurt. My course of action will be engine first, airframe second.
 I must say it does amaze me to see people dive into a homebuilt
 project without a VERY clear idea of how they intend to power the
 finished product. I expect the entire iteration to go relatively
 quickly after I sort out the engine given the 51% rule...What fun.

 Thanks

 I have a Kit plains magazine article coming out in a week or two
 on the physics of the rotary verses the piston engine.
 The newsletter just acquired a running engine with gear box
 on a test stand. Some interesting stuff is coming up. Thanks
 to Milo Burroughs.

My suggestion to you is if you are not planning on redesigning the 13b and
the airframe fit the engine, start working on the airframe while you search
information on the engine.  The 13b has been tested in many aircrafts and we
know that it WORKS fine.  The installation is not standardized so we still
have some problems with that, but not with the engine itself.  Good luck
with your project.
