Wig tip gap at trailing edge - will add epoxy filler

Passed the fixture wire through the mounting hole. Crimped & soldered the power wires to the fixture.  Sealed the connections with heat-shrink & riveted a strain-relief clamp to the spar tip (7V3-3).  Secured the fixture to the fiberglass tip with two #6-32 mounting screws then verified that operation of the fixture by py adding power to the connector in the wing root bay.

Completed the installation by fitting & clecoing (silver)  fiberglass tip in place.  The tip flange slides ~20mm under the end of the compound curve of the nose skin.  Could not get perfect alignment of the 7V9-1 or 7V9-2) due to the compound curves of the win tip structure.  Will fill the gaps with epoxy fiberglass resin & micro-balloons to sand smooth.
