(Page 40-02) Bad hole locations using template

As mentioned in the previous post, drilling holes in the wing skins using the templates in the build manual doesn't work well.  I followed the plans exactly, realigning the template for the top then the bottom holes, marking the hole centers with an awl, then drilling.  This resulted in several holes which were misaligned with the holes in the pre-punched landing light ribs, sometimes by more than a half diameter.  This required slotting the holes in the landing light ribs.  Two holes in the plexiglass had to get the same treatment.  This is a cosmetic rather than a structural problem, but I'm not happy about it.  This could have been done better.

There also appears to be an error in the build manual on page 40-04 step 9.  I believe it should read "Wire to the W-1223B-R" rather than W-1223B-L.  I've reported it to the Mothership.
