Hi Rusty,

Great numbers on the cooling.  I sure like to hear that.  Better than
1500 fpm average to 10K ain't all that bad.  What initial climb rate
are you seeing?

If I ever get my plane flying, I bet I can beat you to 10K.  Of course
I'm starting at 6K. :)

Greetings,
 
I did the official sea level to 10,000 ft climb test today.  It took 6:27
from throttle up, to 10k ft.  Not bad, but certainly leaves room for
improvement.  The OAT was 92 today, and my max oil temp in climb was 186.
The max coolant temp was 213.  Full throttle, level, at 10k ft with the cowl
baffle closed was 180 degrees for oil, and 190 degrees for coolant.  Pretty
dandy all around.   

I did some glide tests, and it seems like the engine is not even running at
idle.  The wideband O2 goes right to 20 AFR, and stays there, while the
engine acts like it's only firing every now and then.  Turning the mixture
knob all the way up really doesn't change anything either.  Does everyone
else's do this too?   Didn't play with this too much, since the water and
oil temps were plunging to the 120 degree range.   

In the hour I put on the plane, mostly at full throttle, there were no other
problems.  The fuel actually transferred, but still erratically, though that
must be due to sloshing in the tanks.  Nothing leaked either, unless you
count the couple ounces of oil that I captured from the vent line.  That
seems to happen any time I run 7000 rpm for any length of time, and Tracy
said his does it too.  At least it's a convenient way to get rid of the
extra oil that accumulates from the premix.   

Today's added bonus picture is the single rotor, and RD-1C sitting on the
Kolb frame.  The engine and drive are just empties at the moment, to make
them easier to lift up there.   

Cheers,

Rusty
