What did you use for setting on the trutrak set ups?
Tom,
Sorry to say, I do not have the settings written down. I can see what
they are this afternoon if you think it will help. I started with the basic
settings they recommended and only had to change the ones having to do with
altitude hold (pitch sensitivity and servo torque I think). However, based on
the different wing, it will probably be different for your airplane. I
recently was up with Linda in her Lightning doing the initial Trutrak set up so
the settings she used would probably be similar for your airplane. By the
way, congratulations on your first flight.
Blue skies,
Buz

I had a great flight back to Williamsburg, Virginia, yesterday, once again
staying lower than I normally fly N31BZ, a modified Esqual with Lightning
Stuff. However, one odd occurrence was having a headwind when on an easterly
heading - very unusual. My initial cruising altitude of 5,500 had about 7 to
10
on the nose which changed to 12 to 15 on the nose when I climbed to 7,500
over the mountains. Later that went to 15 to 20 as I got further into NC and
VA. Dropping back down to 5.5 did not help and gave the same headwind
component.
Once again, my cross country technique is to set the fuel flow I am
looking for and accept the rpm and airspeed this gives me. In this case, at
5,500 when I set 6.0 gph it gave me an rpm of 2950 to 3000 (the altitude hold
causes the rpm to vary as it "flys" the airplane to keep the altitude constant)
and the true airspeed was 155.9 mph. Actual fuel burn from start up to shut
down (remember this would include start, taxi, run up, and climb to altitude)
averaged out to 5.9 gph for the entire flight. Actual inflight fuel burn
would probably be closer to 5.5 to 5.6.
Now having made numerous cross country flights in the 10 to 14 thousand
foot area and several in the 4 to 8 thousand area, I am about ready to say
that you can expect to average about 160 mph (140 kts) true when in the lower
area and 170 mph (150 kts) true when in the higher altitudes. Fuel burn seems
to be about the same in either altitude band. If you want to impress your
non pilot friends, tell them that you get about 28 mpg at 170 mph. Their Nash
Rambler won't get anywhere that at half the speed.
Blue Skies,
Buz

Buz:
Is 2950 a typical cruise RPM? Is that running around 80%, and how does the
3300 like that RPM range?
Jim!
