Hi, fellow rotary enthusiasts....I flew my rotary powered SQ2000 canard
again today. With the smaller prop and my previous mixture adjustments
(enrichening), the engine is producing 5300 rpm static,
and is running very smoothly.  Takeoff roll was short, and climbout was
at 120 knots. Outside air temperature was 70 degrees F.  Now that I am
producing more power, I am producing more heat. I
climbed to 3000 feet AGL, and the water temp got up to 192 degrees in the
climb. Oil went up to 185.  These temps were higher than previously
encountered. The only solution I can come up with is
that the higher rpm's are producing more power/heat.  Fortunately the
temps came back down to 180 water and 175 oil once I leveled off.  I was
able to throttle back and just fly around and enjoy the
fruits of my labor for a while. I need to slowly increase my cruise
speeds and check for flutter (increasing 5 knots at a time), and do some
canard stall testing, but today I decided the heck with
testing and just relax and enjoy the flight.  Temps on descent came down
to around 160 and 155, but of course it wasn't much of a descent (3000
feet down to 1000 feet traffic pattern altitude).  The
aircraft is easier to slow down on final now that I can idle at 800
engine rpm's (365 prop rpm's with the 2.19:1 Ross). I have received my
street ported 4-port engine parts, and I will soon be
putting this together with NA rotors and housings, and then I will swap
engines and probably be able to put the larger prop back on.  Keep
building guys....it's all worth it.  Paul Conner, 13b

Got any pics of your rad ducting Paul? What was the climb out RPM Paul?
New prop size and pitch?

OOps....On my last reply to your questions, I failed to answer your question
regarding climb out RPM and new prop size and pitch.  Climb out rpm was 5400
rpms and the new prop is a 3-blade wood Performance prop that is 62 x 72.
(Old prop was 64 x 78, which I may re-use after installing the ported 4-port
I am assembling). I'm not sure if I will go to the airport today to take
pictures. Cold front has arrived, temps only around 50 today.  Hope this
helps.  Paul Conner

Thanks Paul
