Estes Great Goblin, #9724 Build, Part 12, Gluing On The Launch Lugs

The rear of the lower lug is placed 1/2" from the rear of the tube.

This is a "show" model, the filler primer will have to be sanded off at the gluing area. 

Note the root edge mask down the fin glue area.

Here's a "flying" model build, the seams are filled with CWF but the fins and body tube don't get filler/primer.

The lower lug is glued on the centered pencil line 1/2" above the bottom end of the tube.

I slide the fins in place (dry, no glue yet) to visually double check the centering of the lug.

The rear of the upper lug is placed 10" from the low end of the main airframe tube.

Sight down the tube to check the alignment while the light tack glue dried.

As expected, the dried wood glue fillet ended up with bubbles.

Two follow-up fillets of Titebond Quick & Thick filled the gaps and widened the glued area.
