Here is the bottom view of the wing showing the hinge points. I used a wire to align the points on the aileron. Then I used the same wire to mark the drill points on the wing side arms. I finally got all things line up before setting the respective pieces in 30 min epoxy and hardwood shims. All in all, I'm pleased with the movement. I still need to add in the TE cap. On the top side, I'll need to radius the LE of the aileron and also extend the TE of the wing a bit.
