Travel Struts, Folding Wings, Trim Connector

Now that we have complete wings that are attached, we found a problem when we went to fold the wings.  There was some interference with the back of the root rib.  This was fixed by trimming the edge of the butt ribs and also trimming a little bit of the plexiglass sunroof.  The wings fold very nicely now.

Two rear travel struts were fabricated.  When the wings are folded, these struts pin the wings to the tail to prevent them from moving while towing.  Work has aslo begun on two additional front travel struts.  Brackets were made from angle steel that will attach to landing gear bolts and will be the lower attach point for those struts.

A 4-wire connector, located at the bottom of the tail, was installed on the power and control wires for the trim motor. It was secured with cable ties, which was not a trivial task due to the limited access.  Function was tested and the trim motor moves as expected when the trim buttons are pressed.
