If you use a digital level you can set it on the motor mount and "zero"it. Then
you can take your readings as the plane is sitting. Also, I taped the level
to the bottom of a longer precision level to measure the wing angle on the bottom
of every other rib. You may be surprised at the deviation. Just average
them and try to make the outboard end of the wings close to the same angle so
you have an even stall. The more I think about it I may have turned the back
wing u-joints upside down or used some that Kolb made with the holes in a different
location. Can't remember, but I do remember that Brian had some suggestions.
I think the older "blue" manual had some good tips and suggestions that
were not incorporated in the newer one. I could scan the wing set up part and
send it to you offline if you want. I could also send you pictures of my front
and back wing attachment points if you wish.

Yes Rex... anything you can do will help me out... the manual would be a great
start because i have the new manual and it doesn't mach my plane... also my plans
are from a classic so its all screwed up... can you measure the distance
between the left and right wing roots at the rear by the u joint and where it
is pinned to the fuselage... and no i have not tried rotating the u joints...
i never gave that a thought...

| Subject: | Aileron trim and a new video |
Thanks to all for the aileron trim suggestions a few months ago. I made an adjustable
trim and then had to add a little bit on the rudder trim for the extra
drag. See attached pictures.
Also, I made a new video with the camera mounted outside and added some music.
I'm flying about 2500'. Would like to go lower but a little nervous as some
times no good options for landing if an engine out occurs.
Go to utube and type in "flying a kolb over table rock lake" and it should come
up.

Not bad Rex. The mount seems to be pretty steady. I am surprised that You
Tube allowed you to post it. I had some videos on YT and they blocked the
video's since I didn't have copywrite permission for the song I used. That
is why I went to Vimeo.

"Forgot to reduce the size of the picture. Sorry!"
>>>>>>>>>>>>>>
my curiosity is getting to me...... the picture of the aileron trim....
can you take another picture from further away... is the trim tab mounted
dynamically? does it flex as you move the aileron? or is it fixed?
what is the rod that the linkage is mounted to?
I have the aileron counter weights on my mkIII.... but they go from the
aileron torque tube forward.... Assuming they are dynamic and move as
you move the ailerons.. do they reduce some of the stick pressure like a
spade would do? and then maybe I am over imagining things here....

| Subject: | Re: NEED HELP... Setting wing incidence on a Mk3 Xtra |
Hello Sir,
I have one of the early MkIII Xtra's as well. I did change to the new taller steel
legs and would advise anyone to do that.
Both the Wing and the tail Horizontal incidences need to set correctly and I would
certainly call the factory for the latest settings. I don't remember what
they are but I did set the Leading edge of the HS too low, per a factory letter
for newer models, and this created a dangerous first flight with wayyy too
much UP pitch which could have killed me..
I did get a new universal joint from the factory that was much wider then the original
and I have a bunch of washers to get the wing incidence correct. This
is the trick to getting it all lined up right. The factory reset the wing incidence
to reduce the effect of the wide nose during flight.
You will have to reset the gap seal and windshield fairing again and maybe make
a new one, once all the incidences are set . I remember it took some effort
but I eventually used the original fiberglass parts.
To summarize:-
a/ I'd recommend getting the tall steel legs. There is a left and right and make
sure you install them correctly. I had to redo this as its easy to
b/ Call the factory, get the new incidences for both the wing and tail and a possible
new wide universal bracket.
c/ You should not have to cut any of the flap controls, that does not look right.
AND we will try to help as well..
Regards
FrankD
MkIII Xtra, N1014S

You will probably be fine without brakes. However, I do have a concern.
Consider this; you are going downhill in the rain pulling your trailer. You
enter a tight corner, it's tighter than you expected so you put the brakes
on. All of the trailer inertia is attempting to turn your PU sideways. You
are in prime condition for a nasty jack-knife. I had a close call like this
once on dry pavement.

He also said not to set it up with the adjustable u joints...

Not sure what he meant by adjustable u-joints. The only adjustment I am aware
is with washers. ??

Boyd, It's a fixed tab mounted to an extension of the aileron counter-balance.
I'll send a pix tomorrow.
