Subject: [FlyRotary] Home again,
home again!
Wife, drove me and my flight gear to
aircraft getting there around 1100. By time finished loading,
reinstalling the avionics - the @$#%^ transponder wouldn't slide all the
way back in an engage the pins it was 1130 and the wind was picking
up. - I figured I'd stay low enough and out of class B
airspace anyway.
I told her that she could pick me up back
at the home airport in NC if I didn't have any problem - she said I
wouldn't have any problem. Curious, I asked how did she know I
wouldn't have any problem - "Headwind" she said. Women, got to
love em.
Cranked up the engine and let oil and
coolant temp rise to 120F and taxied to runup at end or runway.
Everything looking good, I restricted takeoff rpm to 5400 (6000 ft long
runway), still accelerated rapidly and lifted off. Kept it low
until hitting 140 mph hoping to maintain good cooling. However,
coolant temp rose to 220F during the circuits of the airport as I slowly
climbed. I pulled the power back to 4500 rpm and the temps
stabilized at 210F. Oil temp was around 185F. Normally
coolant is in syn with the oil or perhaps 5F higher. After flying
for approx 20 minutes coolant temps were at 200F, so slowly coming
down.
This is pretty much what Tracy reported
when first flying with the Renesis engine - tight engine, more power,
more heat. So it appears that this engine is much tighter. I
can now maintain level flight burning 4 gph when it used to take 5.5
gph. Can't wait until its broken in a bit more to see what the top
end is. Overhaul kit from Real World Solutions and parts from
Bruce T appear to have come together in a tight nit engine.
But, it does appear the small cooling
inlets (which I had planned to open up a bit) are too small for the new
HP being produced (are you listening, AL {:>)?. Also, several
people mentioned after I arrived back at GooseCreek that the exhaust
was deeper and louder. Even
my wife mentioned it no longer had that "whinny" sound.
So thanks for all the well wishes from
everyone, advice, and engineering consultation on the cause. I
have mailed seals to Tracy and Bob Perkinson, so that should provide
some "harder" data on the status of the seals.
