Currently still tweaking my build of the A-7 Corsair (http://www.simpleplanes.com/a/5Ebql5/A-7-Corsair-II-v2) but I've yet to work out how to make the entire rear horizontal stabilizers work as the planes elevator. I've seen and downloaded aircraft before which do this but I haven't worked out myself how yet. This video shows what I mean if you watch the jet when it takes off around 1:12 mark (https://www.youtube.com/watch?v=CZmrHUaX7nE)
Since you're on PC you can also nudge a rotator in to the fuselage until it's mostly concealed, set it to be controlled by pitch inputs, and attach the stabiliser to that. You might need to xml edit the range of motion for easy controls, though
just go to edit shape on the control surfaces and make it go all the way.
