Merry Christmas! It's been one year since I received my first kit and started my build.
This took longer than expected and the sequence is critical. I left all the skin rivets open on both sides of the slot which helped, but I did end up drilling out the aft spar rivets to make room for the wedge and hinge bracket rivets. Either way it's a tight fit no matter what, best to follow the directions exactly. I ended up flipping the wing several times with the help of my sons and friend (Stephen, Benjamin and Traegan).
Middle hing rib installed
tight fit with some of the edge rivets
Managed to get to all locations and keep the rivets all facing the same way
