Mark,
Thanks for the kind word.  When you've had as much time under your belt as I have you'll have more skills than I do!!!   Just keep asking questions, and building these things will come!!!  Thanks again for your kind words.

Duco is a very good glue.  I do dilute mine about 50/50 with acetone.  I do what they call double gluing.  I put a small drop on the spot to be glued and a spot on the place that will be glued.  Then when a few minutes have passed I put another drop of glue on the spot and stick them together.  The fresh drop of glue activates both previous drops after they have penitrated the wood a bit.  Makes a good joint.  But make sure the joint is a tight joint.  Duco doesn't make for a filler in a poor joint!!! 
Here's a picture of my Rearwin Speedster to show what I mean by a slot for the horizontal stab.

btw  you trim the model for flight then fill/cover the slot with tissue once trimmed.

With this bird it looks like the vertical stabs are placed on the tips of the horizontal stab so you don't have to deal with a vertical stab on the center top of the horizontal stab.  Often with this type of model the horizontal stab will be glued, after covering, just at the middle front of the horizontal stab allowing the trailing edge to be shimmed up if necessary for trimming.  Quite often in most models a slot for the horizontal stab is made that will allow shimming the front or rear of the stab to adjust trimming.  A soluable glue like Duco will be use that can be disolved with a bit of acetone or thinner.  This will allow re-adjustment of the stab.  Now if you're creative like Mike Kelly you can add an adjustment screw and plate for minor adjustments.  But this is mostly for larger models unless you come up with very small nylon screws.  I'll let Mike give more details on that type of tail mounting setup.
