Well, no homecoming for me. It's my younger daughter's first homecoming tonight.
Last kid at home, so I'm very present to the fact that these are the last
"firsts" for me as a dad. Bittersweet.
Anyway, out in the hanger finishing maintenance, and didn't think I had ever taken
pics of my induction box mod. When I was trying to fix the uneven EGTs a
long time ago I noticed the air filter was VERY close to the firewall, and imagined
there was little room for air to turn that 90 degree corner and flow through
the filter. I made a small aluminum spacer to see if it made a difference.
Well, it DID make a small difference in max speed and RPM and fuel flow, but
nothing for the EGTs. That got fixed later when Nick sent me the vanes and
fiberglass tube. Yay!
I've left this in place just in case it helps a little bit. Don't figure it can
hurt.
Hope the pictures are self-explanatory.

| Subject: | Flying the new larger stab. |
Buz Thanks for writing that up. My
Lightning has always been squirrelly on landings! Greg Hobbs is in the pro
cess of changing out the tail on my Lightning while it is in Arizona. Your
impressions of the revised tail flight characteristics are timely=2C very
helpful and appreciated.
On a different but related subject=2C when watching a video of Nick landing
the Lightning LS-1 I noticed it lands very flat with nose wheel barely clea
ring
the ground. That characteristic is
common in high aspect ratio sailplanes that use only flaps for glide path
control. When talking to Greg about this
he mentioned that one of his homebuilders had shortened his nose strut by 1
=BE inches
to improve nose wheel ground clearance on landing. Greg suggested we try s
hortening mine by at least =BE inch for a trial. You can do =BE inch witho
ut cutting the nose
strut where it would contact the firewall. This allows for a little faster
landing without the nose wheel touching first and causing a PIO to start.
If it
works out well I will try the extra inch later.
Thanks again=2C Gary=2C N335AL Sn 133

Subject: Lightning-List: Flying the new larger stab.
Yesterday I flew two flights in the current demo Lightning with the new
larger stab and to say the least=2C I was very pleased with the flying
characteristics. My concern was that the larger area stab would (please
excuse the term) "dumb down" the wonderful overall sporty feel that the
Lightning has had from day one. No worries=2C it still has that
great sporty Lightning feel when flying around enjoying your "jet".
But I can also happily report that the new stab makes the takeoff and landi
ng
feel in pitch to be much more solid and less quick reacting=2C so Nick's
latest mod has removed any concerns about longitudinal pitch stability that
some
folks might have had when initially checking out in the Lightning. So the
bottom line is that this mod makes a great airplane even better.
A few other observations from my flights yesterday. First=2C on both
clean and dirty stalls=2C the nose is not as high when the stall occurs and
the
stall itself is not as brisk. You still get the "pre-stall buffet"
about 3 to 4 knots before the stall and then recovery is just as quick or m
aybe
even quicker. Also=2C the new larger stab should result in a slightly
increased CG envelop=2C but I don't have the actual numbers for that.
So for those of you with flying Lightnings=2C do you want to order the kit
for the larger stabilizer? The kit itself is actually a carbon fiber
"cuff" that fits over the existing stab and it is then epoxy glued in
place. Not too difficult or time consuming except maybe for the finishing
and painting. Of course=2C the Lightning guys can do the mod for you if yo
u
don't want to tackle the job yourself. So the decision to mod your
Lightning with the new larger stab really depends on you and the way you li
ke
the way your "jet" feels on takeoffs and landings. One other consideration
might be if you ever decide to sell your Lightning=2C you will be able to s
ay that
it has the latest mod that was developed by the factory for the current
LS-1.
Blue Skies=2C
Buz
PS: Lightning builders=2C owners and people interested in the
Lightning are starting to arrive for the annual Lightning Homecoming and
Fly-In. It's not too late to head to SYI. It is again going to be an
educational and fun event.

Bill, you can rotate the filter 90 degrees so the pletes in the filter media
is going side to side, easier for the air flow accross the area between the
firewall and the filter. Small increase but each little things help.
