| Subject: | Lightning Newsletter for November 2009 |
All,
The November Lightning Newsletter (Issue 2-11) is now posted on both
the Lightning web site and Jim Langley's site. Go to either:
_www.flylightning.net_ (http://www.flylightning.net/) .
or
_http://www.jimslightning.com/_ (http://www.jimslightning.com/)
This month's newsletter covers the recent Lightning Homecoming and Fly-In,
as well as the latest news from the factory, dealers, and builders and
flyers. In the factory section is a photo of the newest Lightning employee,
Angi Skinner. Call the factory and tell her hello. Also, you will see the
new Lightning T shirt (modeled by Dana) that you can order. They may even
have polo shirts with the new Arion Lightning logo if enough people are
interested. For either shirt, call or email Mark. Once again, Pete has an
engine clinic article (Jabiru Lubrication), and the safety article has to do
with winter flying and the cautions about icing conditions. In the Tech
Tips section, Tex shares some more tips that he has come up with (maybe I
should call it Tex Tips).
Finally, I have a request. I need some more photos for future "Lightnings
of the month" consideration. So if your jet has not been a past Lightning
of the month, send me a photo of your airplane.
Blue Skies,
Buz

Pete:
Would a 3300 get the same quality break-in in a LSA Lightning as it would in a
standard Lightning? I ask because of the different prop pitch, thus different
engine loading in the two different configurations. It seems to me that the
engine loading of a LSA wouldn't be as great as with the standard Lightning.
I remember that the best way to break in the 3300 is to do several touch and
goes resulting in full power, then reduced power repeatedly.
Perhaps the lighter loading of the LSA engine could be compensated by a longer
break-in period?
Just a thought.
Regards,
Marvin

Marvin,
The rpms and prop loading on the Lightning LS-1 more closely match the
expected RPMs of Jabiru LSA aircraft. I would expect break in to be very
similar. The Lightning EXP when propped for speed puts more load on the
engine but I don't know if that really affects break in. The only times
we've seen problems with inadequate break in is when owners try to baby
their engines and do not run full throttle to climb out and cruise at a
reduced throttle setting of 2300 rpm.

Marvin,
As Pete said the LS-1 would have very similar prop loading to the Jabiru J
series aircraft. I would think that if the engine is propped to run near
3300RPM at WOT than the expected prop load at 2850 say would be the same
regardless of airframe prop combo, than again I think prop load is somewhat
of a voodoo art any ways.

Thanks Pete and Nick,
I am of the same opinion as you Nick :-)
