No kidding! I was thinking the same thing.
Last week, I ask if there were any reliability issues with the Jabiru
3300. (I'm going to use the Jab in my Lightning). No response. I guess
they are 100% reliable. Great!

Good to stimulate some discussion Tex + I too though Gary would get
plenty of info.
For 3300 reliability look to the Yahoo Jabiru engines list, but like
many things folk only tend to speak up when there are problems. We don't
say 'I've just had another trouble free flight what a wonderful engine,
I must tell everyone.
The do soon chirp up when they have a problem, hence the engine forums
are full of problems and if you review them alone you'll think the
Jabiru engine, including the 3300 is a pile of rubbish.
I've experience of both the 2200 and the 3300, they have their problems
slightly more so than any other engine I hear about (Rotax Lyc Cont).
The simplicity, economy and smoothness of the Jabiru engines sway me to
prefer them to the other options.
One comparison I would make is the 3300 seem to have less issues than
the 2200. Probably because they are generally further down the Jabiru
development calendar and maybe cause they are generally under less
strain. Whether that will apply into the future remains to be seen.
The very latest 3300 seems to have been sorted after Jabiru made a few
'adjustments' and I think you'll get a very fine engine! Certainly when
it comes to matching and engine to an airframe the lightning has it spot
on, I don't think there is an option that is even near close to being
worth using.
Regards, Clive
BTW, I now have the sound certificate exemption to go with the permit to
fly for my Esqual, next the insurance and then the UK CAA exemption all
timed for the good weather and my leave in the summer. Getting closer!!

Hi Tex,
A long silence and no activity from me!
I have been mulling over how I can better align the spar bolts/wing
roots/spar box halves without many more trial and error attempts and
consequently larger and larger holes for the spar box bolts in the wing
roots each time. I know that you can flox & epoxy them at the end, but
it's
still better to keep them as small as possible.
I have not made much progress on that, but I have decided that it is a
three
man job to put the spar bolts in - one on each wing tip and one holding
the
bolts. Until now I have had someone on just one wing tip at a time,
while I
do the spar bolts. I have a set of longer bolts that I have filed to a
point
to help get them in and align everything. I have done this, but it is
still
not yet well enough aligned to fit the original bolts.
The builder of a flying Jabiru had a look at my Lightning. He had what I
think is a very good suggestion for checking the wing angle of incidence
which does not depend on the fuselage being level in the longitudinal or
lateral axis, or having a level floor, or on placing an angle
measurement
gauge on exactly the same place on each wing with a jig.
Take a clear plastic tube with water in it. Line one wing up with the
wing
root. Line the water level at one end up with the leading edge where the
wing meets the root. The tube goes under the wing and up to the trailing
edge. Measure the distance from the water level at the other end, to the
trailing edge. This measurement is the vertical height difference
between
the leading and trailing edges.
Do the same on the other wing and adjust the wing position until the
measurement is the same.
Since the wing chord is the same, when you have set the vertical height
difference the same, you have set the incidence angle the same on each
wing.
What do you think?
Colin K.

I did mine by lining the wings up with the 'Karman' which is Spanish for
'wing root shape' on the fuselage. After bolting it all up I went over
it like a rash with a digital spirit level and it was as near as I could
measure.
I wait with baited breath on whether it flies with asymmetrical flap but
live in hope.
One point though, my Jabiru has a tweaked flap to get it to fly
straight, the 'wings' are as level with each other as I can measure and
it seems to be the wing shape rather than the angle that is making it
fly lop sided. I have some eccentric bushes and one take I'm going to
have a tweak at the root to see if I can trim it out. These have been
used where the flaps trimming was too excessive.
Is there a concern with the lighting that the fuselage isn't a good
enough template?

This method ensures that the angle of incidence is the same for both
wings,
but it does not set it to any given value. In fact the manual gives no
value.
I don't think you have any other reference than the wing root for the
first
wing.
Even with the spar bolts in place the wings can be rotated a few degrees
until the angle of incidence bolts are put in place.

Subject: | Seat height and width for new Lightning interior |
Hi everyone,
I'm new here and will be purchasing and building a homebuilt aircraft this fall.
I read on this forum that there were previously concerns regarding seat height
and width for tall/wide pilots. I have heard that the new interior provides
much more room, but haven't found any specific numbers yet. Does anyone know
the seat height (height from the seat cushion to the canopy) and seat width
of the new interior?
I have a sitting height of 38 inches and I would like to know If I will fit. I'll
be at Oshkosh to check it out personally, but it would be nice to have the
numbers beforehand.
Thanks in advance,
Jon

MessageColin, I think your method is ok and the wings being the same is
the finnally point to get to. I took two bolts and tappered them down to
a point and aditional 50 thousands off down the entire lenght of the
bolt, so they went in easier, you will have them on and off many times.
Get to know your neighbors real well and keep the beer on ice. Tex
