Great job on the newsletter Buz! I will certainly try to contribute some
material in the future. Thank you!
I am particularly interested in the new pitch system geometry, the new
electric trim system with an actual trim tab on the elevator, the 1" longer
engine mount, and center throttle.
As I am early in the build process, I am wondering if any of the updates
mentioned can be added to existing kits?
Can anyone share the production status of these updates, and which can be
applied to already delivered kits?
If they can be applied, do they require other modifications? For example,
does the longer engine mount require a different cowling, or do the pitch
geometry and CofG changes impact the need for the horizontal
stabilizer/elevator modification?

Progress on the main gear legs today.
First I cleaned out the paint from the gear leg holes in the spar box. I
used a drill extension and a 1 1/2" wire brush wheel, which I managed to
twist into the 1 3/8" ID tube.
This made a difference but not quite enough.
I bought 48" belt for a belt sander, 120 grade. I turned this inside out
and
used it to manually sand the main gear legs.
It took less than five minutes of sanding on each to get them to fit. A
bit
more on one side than the other as one hole was slightly tighter. I
finished
where I had sanded with some finer grade emery paper. I marked the holes
and
legs 1 and 2, so that I can match them up again after the spar box is in
the
fuselage. The main gear legs are ready!
Not so good with the nose gear leg. I have cleaned out the paint from
the
tube with the drill extension and 1 1/2" wire brush wheel, but the gear
leg
only went in a half inch. I have spent about 20 minutes sanding the leg
and
now it goes in about 3". I am hoping another half hour tomorrow will
finish
the job.
I did use the 1 1/2" wire brush wheel to clean the paint from the
weldment
that goes on the bottom of the nose gear leg and now it fits perfectly!

Well folks, we changed the tires on the main wheels today to Goodyear
Flight Custom IIIs; one of the original tires definitely was out of
round and quite obvious while spinning it on the axle during removal.
The new tires improved the shimmy a bit but it hasn't gone away.
However, we have a new theory: during the tire changing, we noticed
that the axle is quite loose on both main gear. The next idea is to
put some shim stock around the axle to tighten its fit in the socket.
Has anyone else noticed that the axle doesn't fit tightly?
I'll post the results when we get the axle tightened.

Thanks to all for the help in getting a suitable CFI
to help me get my Lightning in the air and finished.

Hullo from Australia, I have kit 32 and my axles were very loose. I
had 2 half inch washers made up for the outboard side with a taper and
holes for the nuts. On the inboard side leave the axle full length and
cut a thread on the axle and a tapered (very small taper) washer and nut
to hold the axle centre and tight, all you then have to do is drill the
=BC hole and AN 4 bolt and nut according to the plans. As it was I had
cut the axle to length so I had a tap put in the axle and bolted it in
with a tapered washer and bolt with locking nut and safety wire to stop
axle rotating.
I do have a question relating to the flaps, when I fitted the port flap
I could almost get my fingers between the flap and wing in the retracted
position. As you cannot unbolt the flap brackets and you cannot bend,
cut or weld them I had larger bronze bushes made and I drilled them out
of centre with the flaps in place. I still have a fair gap as I was
running out of meat on the flap brackets, what do I do now to make the
gap neat and just big enough to clear? The starboard wing and flaps are
just fine.
