--> Yak-List message posted by: "Tim Gagnon" <NiftyYak50@msn.com>
I have started flying my airplane (Yak-50) on more cross countries and have been
using the published numbers for cruise and so on. I was wondering what everyone
is using and what kind of numbers those settings are giving you. Also, what
is a good altitude. I normally fly less than 200nm.
One more question. What is your normal start RPM? Mine is creeping again..
Thanks in advance..

Tim,
For nominal cruise, I am using the same power settings as the 52. 65% and
700 mmHg. With that I am seeing 240 kmph. To play with the 52's, I have to
pull back to 62% and 600 mmHg. That gives me 220 kmph.
I start with the advance opened by somewhere less than a 1/4. Wam up is at
40%. Mine fluctuates between 40%. I do see the usual "twitching" of the
Tach needle but not a creaping up. Have you checked the resistance in the
throttle quadrant? Has you tension loosened up. Sorry..I'm blanking the
term for that knob that tightens or loosens the tension in the throttle
levers???

Friction Lock. :-)
Just for the record I am at the opposite side of the spectrum (what else
is new?). I run the M-14P hard. I used to baby it along at 65% or so,
and put-put-put my way across the country. That was until I started
having serious problems with leading on the exhaust valve, Marvel
Mystery Oil or NOT!
I then changed my tactics. I now run 80% to 85% on a regular basis.
RARELY lower than that. Throttle is pulled back on a cross country to
JUST the point where I see the manifold pressure gage move at all. This
takes the carb off the enriching circuit and saves you fuel with no
significant power loss. I see about 155-160 knots at this setting
depending a lot on outside air temp, altitude, etc. I also change the
oil a LOT... About every 20 hours if possible. NEVER more than 40
hours.
I have run the engine this way for the last 300 or so hours. I now have
just near 700 hours in the engine, and I have one cylinder with
compression that is not perfect. It is about 80/73. The rest are 80/76
or higher.
I believe that with really careful management of cylinder head temps
(shutter position, etc) you can run very low power settings. However,
if you let the engine run too cool with real low power settings, you are
doing it a real disservice.

Mark,
Thanks...having brain lock today... something about the fenzy leading up to
my son's wedding and Bridezilla!
Using the 80% and 800 mmHg manifold pressure, what are you seeing for fuel
consumption on XC's?

| Subject: | Re: ACR Personal Locator Beacon super deal |
Just thought I would pass along this great deal on ACR 406 Personal Locator Beacons
with internal GPS. Just bought mine from James (special pilot price) for
$550.00 then you get a $75.00 rebate from ACR until the end of this month, for
a total price of: $475.00!
Thats lower than dealer cost by the way. Give him a call at: 1-800-743-7238 and
tell him your a pilot and that you saw it on the Yak List.
Happy Flying!
