I have my wings mounted in my frame started putting on the skins. I first
used a single jack in the center to take the sag out of the spar but it
doesn't seem to take it all out, especially on the root end. After getting
the skins on, I noticed I had some oil canning in a few sections.
I'm curious for those of you who have or are working on your wings, did you
use more than one support to take the sag out? Do you have any oil canning
in your wings? I need to get a couple more jacks and some plumb bobs to
make sure everything looks kosher.. but just curious.

Matthew,
Once the skins were clecoed on, my wings were very rigid. I only used one
support (a 5 gal bucket and an old car jack) in the center. When you put
all of the skins on, the oilcanning should be a thing of the past..
My wings came out within 3/64th of being true with no special care
involved. I personally think that you would have to screw up very badly
to have the wings come out very far from true.

I found the same problem in my wings with oil canning but the solution
turned out to be the twist and not the sag. Some of the holes on the spar
were off by about 1/16 of an inch... the match hole technology has always
been so good I just shoved cleco's in which was a bit mistake. The solution
turned out to be to take the skins off, cleco in all the properly aligned
holes, check the twist was good and then match drill the bad holes and
cleco. The twist was good and no oil canning. If I remember right this was
on the outboard wing panel of the right wing.

This is something I have struggeled with... I subscribe to both the Matronics rv9
list and the Yahoo rv9 list. I simply route the emails with a rule into a single
incomming folder. Then I read & reply to what ever message is of interest.
That means that some of my comments land on one list or the other depending
on where the question was asked. I agree with others that yahoo is a spam source
once you give them your email...
Keep up the building, and ask away if you have questions.

What kind of antenna cable connectors are used for Com and Nav radios? Is
there consistency among manufacturers?

I just cut a plastic pipe and shoved it in to hold the rear spar level. A
few shims to make sure it was really level did the trick. With all the skins
clecoed on the wing was as straight as I could measure.

Any opinions on a two power pack wing tip strobe setup over a single wing
tip strobe arrangement? Must make a decision before OSH QB wings&fuse are
on their way .

--> RV9-List message posted by: ivo welch <ivo.welch@yale.edu>
I guess oshkosh is a big draw and why a lot of people have not been around.
well, in case anyone is interested, I purchased a nice little RV-9A from
kevin shannon about 2 years ago. over the last month, noel simmons
(from blueskyaviation.net) has been doing a lot of avionics and other
upgrading for me, and it appears that he is doing a great job at it
right now. I am very pleased so far. also, reasonable pricing, though
quality work is first and foremost. I plan to write a webpage about the
upgrade job and put it up, too.
the point is that I think noel is planning to fly to oshkosh with
n994ks, too. So in case you want to see a real nice panel job, nice
quality work from builder and upgrader, and chat about 9As, you should
try to find noel there.
hope this helps some other builders.
regards,
/iaw

| Subject: | flight characteristics |
--> RV9-List message posted by: Im7shannon@aol.com
I remember reading somewhere that the prototype 9A had a stock RV 6 tail, and
the reason for making the horizontal tailplane larger was to compensate for
the pitching moment of the new airfoil.
My question to those of you flying now, when you are putting along trimmed
out for straight and level flight, are your elevators in trail?
994KS always needed a degree or so of down elevator to trim out. Are you
reading this Ivo? Have you noticed this condition? I am wondering if changing
the
angle of incedence of the HS from zero to +1 degree might help keep the tail
up at cruise. What have those of you flying noticed?
Thanks, Kevin
I am using this airfoil on my Colt49 "scratch" build (now I see where the
term scratch build came from after I scratched all the hair off the top of my
head)
