These went together really well...the rudder/fin are simply glued over a single layer core paper and after the fin was on, a fillet wrapped around perfectly to give some strength.
Then the stab has a fine wire spar which slipped into the fuselage, poked out perfectly on either side and served as some solid real estate for the sandwiched stab. I dropped the elevators a bit too. Here is the sequence:
I think I'll be able to start the engine and cowling next. Starting to look good!
