Hello Tim, Thanks for the pictures. I found picture 059 (see attached) to be
of particular interest.

Note that the laterally fixed cross bar between the control sticks in that
picture is round and has an adjustable aileron stop bracket (by means of a
through bolt) welded onto the bottom of the round cross bar. This bracket is
probably what Keith Miller was referring to in his posting on the subject of
aileron control stops.

When you look at picture 0371 (also attached) you can see that the laterally
fixed cross bar has been changed (in my kit # 116) to a square configuration
and there is no adjustable aileron bracket welded onto it.

It also appears that the vertical position of the laterally fixed round
cross bar in picture 059 is higher than the laterally fixed square cross bar
in picture 0371 with relation to the wing spar mounting box. This would
result in the push rods going out to the ailerons also being higher in
picture 059 than in picture 0371.

Maybe this would account for the fact that Hans Christian found that the
holes in his wing ribs did not match the long aileron push rod vertical
position. Perhaps Tri-R made a change in the laterally fixed cross bar from
round to square and at the same time lowered the vertical position of the
laterally fixed cross bar. What say you Rich?

Also note the significant difference in the fore and aft vertical support
going to the wing spar mounting box in the two pictures. In picture 059 you
can see the exposed edge of the plywood core of this vertical support. In
picture 0371 you can see an extensive amount of fiber glass lay up entirely
covering this plywood core, which is presumably inside the fiber glass lay
up. This lay up was done at the factory as part of the fuselage quick build
feature by Bill Grote and his crew. (Bill are you still on the list? Anybody
have an email address for Bill?)

'OC' Baker Says: "The best investment we can make is the time and effort to
gather and understand knowledge."

PS: Tim, I noticed that you sent a copy of your 8/7/2010 email copied below
to the matronics aeroelectric-list rather than the matronics kis list. I
imagine that that puzzled a few of the aeroelectric-list readers. Do you
want to send your email again to the matronics kis list so that the archives
there are complete?

OC

I can confirm that on my kit #079 has the fixed cross bar with the welded
bracket for the aileron stop. This is also the same cross over bar that is
illustrated in the build manual (which clearly shows this welded bracket ) .
Not sure why Rich would have changed this to the other design as it looks
simple(Cheap) to make . as for the position of the aileron tubes going out
to the wing , I also initially had the same problem as Hans , but I then
mounted the two stick assembly brackets attached to the spar tunnel upside
down which lowered the assembly enough to provide the correct clearance.

Keith
