Kevin,
Congratulations. After engine break-in you should see CHTs drop by 25 =
or more degrees. Also, since your CHTs are so high, it is no wonder =
that your oil temps are running high. I had a lot of trouble initially =
with high CHTs. I installed baffles around the cylinders so that only =
about 1.5 inches was open at the bottom (I got this off of Burt Rutans =
web page). It works wonderfully. Also, make sure you have VGs =
installed on your NACAs and make absolutely sure they are set right =
(i.e., the difference between the front and the rear separation distance =
of the VGs must be 0.75 inches).
Good luck. I have almost 200 hours on my Std Elite RG and it is running =
wonderfully. I'm currently getting my instrument ticket in it and it is =
just a blast.
Cheers . . .
Jack

After 3 years and 4 months of building, this past weekend Mike =
Pollock, Velocity owner and test pilot, made the first flights of our =
Velocity, N111VX. My wife and I flew chase with Milt Mersky and Dave =
Bertram in Milt's & Mike's Velocity.

Elite Long-Wing, Fixed-Gear
Empty Weight 1505

Saturday 6/28: The outside temp was about 90 (it was morning) (it's =
hot in Scottsdale, AZ now). CHTs were high (over 400) on taxi. She =
flew beautifully for about 15 minutes over the airport but the oil temp =
was slowly rising. At 245 degrees, Mike decided to land. The lowest =
oil temp on descent was 230. Mike said that the wire duct was quite =
hot. CHTs were high but under 425 in flight. Oil reached around 256 =
and CHTs reach around 467 by the time Mike taxied back and shutdown. We =
were expecting high temps until the engine was broken in but the oil =
temp was concerning. Duane Swing suggested that a small NACA scoop in =
the fuselage at the forward end of the pilot wire duct that holds both =
oil lines would help by keeping the lines cooler in flight. We put in =
the NACA scoop (or hole for the time being) and the next morning we flew =
again. CHTs were below 425 (mostly around 370-380) and oil temp was =
below 245 the entire time. Between the engine slowing breaking in and =
the small NACA for the oil lines all temps were in check. We flew for =
almost 2 hours in the local practice area around 6,000'. Mike did slow =
flight, stalls, steep turns and flutter tests - everything went fine - =
she flew beautifully.

still can't find the words.
