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 powered SQ2000 canard
