Wow I think your right. Is this a common way
When I built my lamyak 40 I just glued the bottom spar at the root ribs and then did everything needed to the top of the wing. After I was done with the top I flipped it over and then pressed the spar all the way into the slot and finished gluing it.
Looking good. Keep asking questions when you have them. We want you to have the best slab experience possible. They are more fun than you could ever imagine.
