          strut problem)
      
      I and at least several others encountered this same problem with the 
      front strut while building 701's.    In our case, the relative angle 
      between the lower fitting on the landing gear and the upper attach point 
      on the wing was wrong.   These were on the one-piece struts where the 
      entire strut was welded in a single piece, and right and left side were 
      off by the same amount.  Solution was to cut the top ends off the struts 
      and top it with a sleeve (purchased from Zenith--in my humble opinion 
      they should have provided it at no charge) that was free to rotate to 
      the correct angle, then drill and bolt it in place.  From what I 
      understand, Zenith subsequently went back to providing 2-piece struts 
      for the 701s to avoid this problem.  Check the 701 archives for details. 
       II'm surprised to hear they are back to one-piece in the 750, but if 
      the problem is the same, the solution probably is too...

      The wall thickness is not constant. The struts are extruded and the ends are
      thicker than the midsection.
