11. Glue the rear nose former to the 1/8” ply front nose

former (K) with medium CA, being careful to align all three
holes in both parts as shown in the photo. Be sure the three
punch marks in K face out.

12. Trial fit the nose former assembly into the nose of the

fuselage. If the front nose former extends beyond the sides
of the fuselage, remove the assembly and sand it until it is
even with the sides. Do not sand it while it is fitted into the
nose as you can easily damage the foam fuselage. Once
you are satisfied with the fit, glue the assembly into place
with 6-minute epoxy. Remove any excess epoxy using a
paper towel dampened with denatured alcohol.

1. Glue the 1/8” balsa pushrod brace (G) perpendicular

to the 1/8” balsa servo tray (H) with medium CA.

2. Glue the servo tray assembly into the fuselage with

6-minute epoxy. The cutout in the front of the tray should
align with the front of the rear LG former.

3. Install the pushrods and guide tubes into the

fuselage by inserting them in the holes you made in the rear
of the fuselage. Do not glue the pushrods into position until
instructed to do so. The pushrods cross inside the fuselage.
The elevator pushrod, which exits from the right side of the
fuselage, has the ends bent at 90 degrees to each other.
