Thanks Tracy, and all other well wishers.  I really appreciate your
comments.

I have some indication that the temps might not have been as high as I
thought.  I need to recheck my calibrations.  I was also seeing 7500
rpm at about 100 mph and climbing at 500 fpm.  That doesn't leave me a
lot of room to go faster so I think my prop isn't going to work even as
well as I had hoped.  I will just call this my Cessna 150 emulation
mode.
