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.

  =20

  Elite Long-Wing, Fixed-Gear

  Empty Weight 1505

  Re-Man IO-360-C1E6 from Lycon (in CA) with high compression pistons

  M-T Prop

  Single oil cooler (in front)

  Downdraft cooling

  Presently in primer, no interior (just seats)

  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.

  I should have my transition training completed sometime this week and =
will hopefully personally fly her before the weekend.  Can't wait and =
still can't find the words.
