TIP: Joiner rods on the fuselage have diameter
of 4 mm, carbon spars in wings have inner
diameter of 4 mm. They should fit into each
other but sometimes the fit is too tight or you
cannot insert joiners rods into wing spars at all.
You can use drill and wet sandpaper to make
joiner rods thinner. Use breathing mask to avoid
inhaling carbon dust!
Remove support legs from all parts. Also sand all sharp edges
and printing imperfections to avoid covering foil damage.
