Here is a quick update of the SA-5 progress. I glued on the antennas, the umbilical door, and the hydrogen vent pipes. The umbilical door is cut from .005 sheet stock while the antennas are cut from some strip stock I had that looked close. The hydrogen vent pipes look a bit different that the last update. I added the short straight section after the bend at the top of the pipes. I at first thought I could leave it off, but the more I looked at it the more I knew that the short sections needed to be added.

The bottom of the vent pipes needed to have a slit cut into them so they could fit over the stub fins. Also note that I have glued the fairings back on the base of the vehicle.

Here are a couple of pics of the stub fins dry fitted to the hydrogen vent pipes. Note in the pic on the left that I have also drilled the vent holes in the tops of the fuel and LOX tanks. The pics also show the LOX and fuel fill and drain ports.
I also fashioned some hydrogen vents for the stub fins that will be glued on later.

I have also filled the areas on the inboard nozzles where Airfix had molded in for the turbopump exhausts. The inboards on the Block II vehicles exhausted their turbopumps out the sides of the boat tail in aerodynamic ports which are not yet installed. The outboards will require some modifications to look more like the real thing. The inboards need some extra details as well, they were not simple curved bells.
That is it for now. Thanks for looking.
