Had a little free time today so I finished the flap hinge modification. 

Similar to what a lot of rv builders do, I cut out three of the loops and then bent the hinge pin at 90 deg. This allows the hinge pins to each the last loop on either end. 

Not shown here but I took two loops from spare hinge material and will fabricate a bracket that will be screwed to the flap brace. Then repeat the same thing for the other wing.
