Rans, (and ACS,) sells a "kit" to install a manual trim on their S-12. I am
adapting that kit for a manual trim on my plane. It definitely requires
some engineering.

me (I'm an electrical engineer), but I don't know how hard it would be
to modify the elevator, etc.

Adding electric the "right" way:
1. Strip one half the elevator.
2. Fabricate trim tab.
3. Cut and weld elevator to fit tab.
4. Weld in a bracket or support for the servo.
5. Install and wire the servo. (You know how to do that.)
6. Attach the tab using piano hinge.
7. Check it all out to make sure it works. (I'd guess 10 degrees up and 40
degrees down, depending on size.)
8. Re-cover the elevator, including access for the servo and hardware.
9. Paint and trim.
Now you could do all of that externally, including a bubble for the servo,
but you'd still have attachment problems, particularly since the elevator
is made from very small tubing.
