I did last minute touch up sanding and surface prep on the canopy skirt and then primed it.
I mounted the aileron trim servo and added the spring clips to the aileron actuator tube. First I mounted the servo to one of the wing access panels and ran the actuator arm to center. Then, with the actuator tube connected to the aileron, I set the aileron to the center position using the rigging template attached to the end of the wing. Finally I lined up the mounting plate to the hole in the wing and used a drafting triangle and angle measure tool to transfer the center point to the actuator tube.
I then removed the actuator tube from the wing, marked the positions for the spring clips and drilled the rivet holes for the clips.
