Yes, I glued the tabs into the wing.
Bottom wing first. I applied some thick CA into the wing then inserted the strut with the tab attached to the strut.

When it was dry I positioned my top wing to get the correct incedence. Then I used thick CA on the top tabs that are already secured to the strut and put on the top wing. I rechecked my incedenece and taped it in place.

After I was sure the tabs where secure I disassembled the struts from the wings and poured thin CA into the tab slots to secure them further.

FWIW, this is also covered in the manual.
