❏ 8. Use 320-grit or 400-grit sandpaper to roughen
the outside of the 11/32"x 6"[8.7 x 150mm] brass
tube and the inside and outside of the 3/8"x 1- 1/2"[9.5 x 38mm] brass tube so glue will adhere.
❏ 9. Use 30-minute epoxy to glue the dowel spar
and tubes together—both tubes should be centered on the dowel. From now on this assembly will be referred to as the stab spar. Note: It may be necessary to sand down the dowel to get it to fit into the 11/32" [8.7mm] brass tub.
❏ 10. Enlarge the holes in the nylon swivel clevis
with a #40 drill.
❏ 11. Slide the swivel clevis and two 3/32"[2.4mm]
wheel collars onto the 4-40 control rod. (The set screws will be installed and tightened when finalizing the radio setup after the model has been completed.) Slide the bearings over the stab spar. Fit the ribs on the pushrod and the stab spar. Working over the stab plan, fit the assembly to the die-cut 3/32"[2.4mm] balsa sub leading edge and the die-cut 3/32"[2.4mm] balsa sub trailing edge. Join the rest
of the ribs to the assembly.
❏ 12. Hold the stab assembly to the building board
with T-pins. Glue the ribs to the sub leading edge and to the sub trailing edge.
❏ 13. Securely glue the stab spar and the stabilizer
control rod to the ribs.
❏ 14. Use a razor plane followed by a bar sander to
shape the top of the sub leading and trailing edges even with the tops of the ribs to accommodate the sheeting. Make sure none of the T-pins are in the way.
❏ 15. Sand the trailing edge of the plywood S1 ribs
to accommodate the balsa stab trailing edge.
❏ 16. Remove any T-pins from the stabilizer
assembly that will be concealed under the stab skin when you glue it into position. Glue one of the stab skins to the top of the stab. Thick or medium CA could be used, but aliphatic resin is recommended because it will allow more working time for positioning the skin. Use T-pins and weights to securely hold the skin down until the glue dries.
❏ 17. Remove the stab from the building board. The
same as you did with the vertical stabilizer, trim the bottom of the sub trailing edge and the bottom of the sub leading edge even with the ribs to accommodate the bottom sheeting.
