I wasn't up for fighting with the canopy tonight, so instead pulled out the electric aileron trim to see how that all goes together. I neglected to take photos of the actual fabrication and how the mechanism all goes together, so here's a beautiful picture of the plans:
I drilled the holes and notches in the block that holds the pivot arm.
Lots of layout, drilling, nutplates, etc later, I had the attach bracket made and the block and pivot arm mechanism attached. I screwed the bracket to the center seat ribs. I haven't located and attached the servo motor itself yet. That'll be up next.
