Hi, Steve....glad to hear the temps are down. Please keep us NACA canard
drivers posted with results from the new scoop you make. Thanks for sharing
this valuable information. Paul Conner, rotary powered SQ2000

Subject: [FlyRotary] Temps finally down
I made my eight flight today, and I'm happy to report that my inlet scoop
augmentation on the Cozy did the trick.
I flew only about 1/2 hour because I had some other work that I wanted to
do
on it, but the temperatures ran at 190 coolant, and 200 oil.
I climbed up a couple thousand feet, and instead of throttling back and
watching my temperatures come back down from 210/220, I wasn't quite up to
a
stabilized temperature yet. That was a big change. I pulled power back
to
what I had been running previously, and the temperatures stayed the same,
maybe dropped a little. I then throttled up to zero boost, and the
temperatures held. YEAH !!!!! They used to climb up with the throttle.
On the decent to landing, I thought that I would have to chip the ice off
of
the engine. Coolant dropped almost off the gauge to about 140, and oil
down
to 160. Actually when I touched down, they were even lower than that.
Now that I know that I can cool it, I'm going to make another scoop,
narrower on the sides, but a little taller (actually lower) to get a
little
further outside the boundary layer. The next scoop will have a smaller
inlet area compared to the current one.
