Brief Description: Rear Spar Attach Fiittings - make to fit!
Thanks to Paul Minelga's Kitlog site, I had a warning that there may be issues if you make the rear attach fittings per the templates on the plans. I found that if you drill the holes in the forward fittings per the template in the plans, it is further out than the 1 1/16" REF dimension shown on the plans. This is actually a good thing because at 1 1/16" hole spacing, there is little to no clearance between the fitting and end rounded end of the spar.
I moved the hole out to match the forward fitting spacing and added some material length.
Drilled forward fittings to 1/4". Step drilled the spar holes to 1/4"
