    Subject: Re: Seat height and width for new Lightning interior
    Good morning It is my understanding that you must cut the seat base and drop it to the floor of the fuselage, then re-glass it for the lowered position to gain more clearance for tall pilots. I am 6'3" tall and I too had problems with head clearance in the standard Lightning. This procedure sounds like a workable solution.

    MessageGood morning. Doesn't Lightning now have a template for setting wing angle of incidence? Gary ----- Original Message ----- From: Colin J. Kennedy To: lightning-list@matronics.com Sent: Saturday, May 17, 2008 9:24 AM Subject: RE: Lightning-List: email 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.

Kennedy To: lightning-list@matronics.com Sent: Saturday, May 17, 2008 7:43 AM Subject: RE: Lightning-List: email 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.

    A drawing with measurements and method are described in the manual. There is no template. I really don't know if that would help or not. It might. Colin K.

Hi Colin, I used a "water level" extensively when rigging my Pitts. The neat thing about it is that it can be any length - such as wing tip to wing tip. The method you describe above should work. However, I think the new incidence jig that Lightning has come up with will be simple and likely do a more precise job when using one of the new digital levels. But as I said, your "water level" method will work. Blue Skies, Buz **************Wondering what's for Dinner Tonight? Get new twists on family favorites at AOL Food.

Hi Clive, The karmen on the two fuselage sides are probably pretty close in the original molds, but that may change over time with use. Plus the individual layups could vary, as could the way the two halves are glassed together. All of these processes leave some room for very slight miss-allignment of the karmen on each side. In the past, some Lightnings have come out with no roll when using the karmen and others have had a roll to correct. So it just depends. The new jig that SYI is using makes sure both wings are set to the same incidence. Adds one step to the process, but insures they are the same.

    I am 6'-2", but have a torso/sitting height of 39.5". I fit with just enough clearance for my headset. I lowered my seat by cutting out the seat support and center console where is rests on the spar box enought so it sits flat. I think I have pics on my build log site. Go to www.jimslightning.com and then go to the build log. It is hosted oin mykitlog.com Jim!

    Thanks Jim! I've been following your builder's log for a few weeks now. Great work, and a great service to the homebuilding (and potential homebuilding) community. As you already know, it is a bid of a challenge to find planes that fit those of us with long torsos. :D Now I am even more psyched about getting to see the plane up close at Oshkosh.
