Paul,
              I would like to subscribe to your newsletter. By the way
I was a Flight Test Engineer on The V-22 Return to Flight Program at Pax
River for several years (2001 to 2004). I could tell you some stories.

I would love to hear them. Scaled down I think the concept
could be a whole new  sector of general aviation.

Here is something I am working on. I am also working on
improving a youtube video I have on the concept.

How is Boeing coming along with the variable twist
rotor blades? IMHO that will make the entire concept
much much safer.

           Unfortunately I left the program right after the return to
flight phase and were able to get the V-22 fleet flying again. I believe you
are right about the IVO prop concept. In fact Sikorsky uses a similiar
concept with the H-60 (Blackhawks/Seahawks/Jayhawks/Pavehawks) tail rotors
and I can speak as an H-60 crewchief and former H-60 test engineer that this
is the best tail rotor design there is. We have never had a tail rotor come
apart on an H-60. But to emphasize your point, we have had cracks on the
V-22 rotor hub and retention system. We were still trying to find solutions
to that when I left the program. Nothing drastic, but you had to watch for
it during inspections.
          I am building a Cozy Mark IV with a Rotary 13B Turbo. I am not
using a stock Turbo because of the change air density at around 10k feet so
I am using a much larger one. Being my expertise is in electrical and
avionics I hired a mechanic to put the engine together that is experienced
in aircraft conversions. I have been reading the articles about leaning and
power management and I find them very interesting. I am considering
buying your book on Cooling Your Wankel as well. Also to your credit I have
been looking at the IVO constant speed or adjustable props and I have
already decided to put it on my Cozy. Keep the good info coming thank you
for sharing some very much appreciated knowledge. Once my engine is
completed I will provide pictures and stats on the components and operation
to add to the library.
