Has anyone experience or knowledge on how to retrofit wingtip nav lights after the wing has been constructed? Thanks

No direct help, but if it is an XS wing, do make sure that the installation is airtight. The XS floats because of the air trapped in its wing If you don't seal efficiently around those lights it will become like a PA28 which sinks in 3 minutes! Regards, David Joyce, GXSDJ

Thanks David... its a classic; so foam core wing construction.. as far as i can tell from construction information the chord ribs are solid; i canâ€™t think off anything other than making up a 1/4â€ or 3/8â€ bore mounted on a long tube; unless someone knows of an allocated area in the factory material for this purpose.

I seem to remember an article about this in the Europa Flyer - you might try the new search facility on the club website. Personally I would be tempted to run your wires along the wing close outs. You could no doubt find a suitable three core flat wire and bond it in place and then drill a hole between your wing tip opening and the outer aileron close out. Best of luck, David

I've done just that with Creighton Smith on his 96EG (Classic) rebuild.  The plane was to be repainted but obviously we didn't want to screw up the finish and make more work.



I used a 1/2 inch chrome moly tube with a sawtooth cut (like a hole saw) in one end then sharpened it to make my drill.  

I drilled forward of the spar in line with where the lightening hole would be just forward of the spar (leading edge side).  In the Classic manual you can see where the lightening hole is in the foam.  Often you can clearly see the spar location and if you look closely, the hotwire line in the wing is also visible (which is the center of the lightening hole).  The port wing was perfect but we got off a bit in the starboard wing as we hit the bottom of the skin just as we got to the end of the spar.  We were lucky.



Drilling:

I was responsible for the spanwise alignment of the drill (I snapped a line on the wing) and Creighton was responsible for the elevation of the drill.  We drilled through the solid foam of the walkway root area nervously.  Then when we hit the lightening hole, I pulled the saw (tube) and used my borescope (Amazon 15 footer that displays Bluetooth to my cell phone) and a bit of feel to align with the bulkhead in the outrigger area and drilled center in that.   The tip area was easy as the original builder left off any reinforcements so all I had to do was angle the hole back slightly to get a hook on the wire.



I'm hazy on how we ran the wire through the hole, I think I used my fish tape and attached the wire or a string with a loop and inserted it through the drill tube and pushed the fish tape through to the tip.

Once we hooked the string or wire through the tip hole, we pulled it through the tip, we made a tip support out of ply and mounted the Aveo light.



On 12AY (Classic Kit A054)  I planned a 3/4 inch black butyl tube through my wing.  It was a lot easier.



Best Regards,

Bud Yerly
