|
|
John:
If I move the attachments, I will have open holes
corresponding to the original placement. I have
considered to use inserts to compensate for the
possible weakening, whose length may be most of the
length of the spar.
What do you think about this option?

José Toro,
If you change the length of the wing struts, you
will affect the angle of
the bolt holes that were drilled in the spars at the
airframe mounting. Even
a little length will render the current spars
unusable or worse if you bow
them to fit, the spars may fail in flight. Also you
can not move the spar
connection for the lift struts with out weakening
the spars. Please consider
this .....
Thanks, John Oakley

José,
You are right, new inserts, longer, may take care of that problem, although
the new attachments will probably over shadow the existing holes. The real
problem is the vertical holes drilled in the spars at the fuselage
attachment point. It may be easier to have the new struts made to order at
the factory. John could use a little support anyway.
My fuselage was out of square by about 3/8 inch and I set my attachments
different on each side to make it up. The wings come together when I folded
but are several inches different in height when out, you can see it if you
look close. The plane in the air doesn’t know a thing.

John:
With different length lift struts, the difference in
height was obvious when wings were folded, about three
inches at wing tips. Like I mentioned in a previous
e-mail, it was incredible how nice this plane flew for
over a decade with these assymetries.
Thanks for your feedback!
