From: "PatrickW" Wouldn't the overall wing strength be compromised more by cutting the top skins for wing lockers than it would be if the top skins were left intact and 40 lbs were hung in the area someplace near the CG between the main gear and the firewall? I thought the wing derived significant strength from it's skin? My wings are complete, except for final riveting of the top skins. I have the wing locker option, but have not cut the skins at this time. The idea of leaving the skins intact for reasons of strength, and exploring external cargo storage options is an attractive idea.

From: "leinad" Patrick, I'm not an aeronautical engineer but part of my thinking on this issue was that the cut outs are mostly effecting the negative G strenght of wing since they are on top. I'm going with with the wing lockers.
