The complete version of my modular wing section. I am intending to go on to build and fly a full model aircraft with many 3d printed components in the future. This is a step in that direction
De-burr and glue
The spar and ribs mechanically fit together and are tight! you will need a good de-burring session to fit them. similar for the leading and trailing edges but not so critical.
the spar, although cool, is not really functional, its quite heavy and not as stiff as i'd like. leading and trailing edges are hot glued on.
