Not happy with the twisted twin's rear, I attacked it with a razor saw...
My razor saw is none too fine, and despite efforts at keeping everything square, and the cut on the panel line, things went a little out of true. No matter, nothing that can be cured with laminated plastcard.
Once this lot has dried off, I'll sand it to the same profile as the rest of the fuselage.
The joint itself will be on a panel line, and therefore shouldn't need filling, as well as allowing me to rotate the fuselage back to the correct orientation.
