I found some aluminium parts (a skin send in error), which allowed to go forward with the wingtips. First I made a cardboard template, then I cut out the parts.



Then they get folded and matched to the wingtip.



Then the parts get drilled for the strobe and the LED support. On the latter part there is heatsink and the wiring support which are protuding and so I had to drill out the opening in my part.


I still have to drill the wingtip, tidy up the rectangular opening and take off the blue and brown protections.
