The comments from NC had me looking at the control rod runs again. A little more work with a round needle file and the run is almost straight. Still in a good direction to meet the horns. Now glued and an extra brace to hold where they exit the fuselage.
Also soldered threaded rod to the ends of the pianowire and put z-bends at the servo end. Now, if only I could find the bag with the spare horns and the little screw. I have one, but not both....
Next I need to join the tail surfaces on and do the bottom decking. For that I need to paint first, as the rudder is a different colour. While waiting for paint to dry I painted up the top wing gun. Also tried working out a more scale exhaust. The plan calls for 9mm half round, which is a bit big, and the full size is separated from the fuselage. This is using a bamboo skewer:
I think it will work, when I get that far.
