Matt,
There are some pictures of my installation on my site
www.gapilot.com/construction. Or go to 'Construction Information' section from the main home page. You will see the Duckworks landing light listed.
While you are working on your wings thinks about your cable runs, and how many cables you have. I fitted my wings at the weekend and found running the wires hard work. Especially as I did not originally plan to fit an (EZ-Pilot) servo in the wing. So there were more wires than I anticipated!
Hope it helps you out.
Regards,
Tim.
