Sorry Vance, but the reality of my 600+ hours on this gyro doesn't add up to
a wash between static and flight...   on a static run-up, the rpms get to
6250, but flying with enough air to keep the blades spinning, I usually peg
the 7K at 6990 (digital readout)....( 25 mph airspeed minimum and usually
<80 mph max.)   I am using a 10.5 degree prop pitch setting...( this should
be enough to get the number crunchers going crazy).... BTW, I will burn a
little over 14 gph if I can tolerate an entire hour of roller coaster flight
at almost WOT... more likely and probably more accurately, I will get the 14
gph with a probable average engine rpm about 6200.... I don't know how many
of you guys can stomach the entire hour on "the steroid hummingbird"... I
know when I'm finished, I need lots of time to calm down and get my senses
retuned to ground speed!!

Now here is a guy getting some real HP out of his rotary engine.

If you assume he has a real bad carburator system and his BSFC
is 0.55 at 14 gallons an hour Gary is looking at 153 HP.
At 0.50 it is 168 HP. Not bad from a 12A.

Most people burning 6.8 gallons per hour in their rotary are pussy 
footing around at 74 to 82 HP.

Looks like you can might use another blade once you find a way to get
another
20 HP out of that 12A at 6000 RPM Gary. Go for peripheral rotor
housings,
long intake runners and fuel injection. A 13B would just add weight and
some power of course.

BTW how is your Ross gear box holding up Gary?
