BUILD THE TAIL SURFACES
Build the Stab
❏
1. Tape the Wing/Stab Plan view to your building
board. Cover the plan with Plan Protector.
❏
2. Locate the two die-cut 1/8" [3mm] balsa stab
center pieces. Glue them together with medium CA
to make one 1/4" [6mm] stab center.
❏
3. Locate four die-cut 1/8" [3mm] balsa stab tips.
Glue them together to form two 1/4" [6mm] stab tips.
❏
4. Pin the stab center over the plan. Using your
plan as a guide, build the leading edge and trailing
edge of the stab from 1/4" x 1/2" x 36" [6mm x 13 x
914mm] balsa sticks. Cut 1/4" x 1/4" [6mm x 6mm]
balsa sticks to the proper length for the stab ribs.
Glue them in place with medium CA.
❏
5. Glue the die-cut 1/8" [3mm] balsa gussets in
place next to the stab tip on the left side of the stab.
Center them on the 1/4" [6mm] stab parts. Repeat
this for the right side of the stab.
❏
6. Glue the remaining gussets in place as shown
on the plan.
❏
7. From 3/32" x 1/4" x 36" [2.4mm x 6 x 914mm]
balsa stick, cut out cap strips and glue them in place
on the stab ribs. Do this on both the top and bottom
of the stab. Note: On the stab cross-section you will
see that the cap strips extend across the leading and
trailing edge.
❏
8. Sand the cap strips to the shape shown on the
stab cross-section. This is also a good time to final
sand the leading edge of the stab. Use the cross-
section as your guide for sanding the final shape.
Build the Elevator
❏
1. From the 1/4" x 1-3/4" x 36" [6 x 32 x 914mm]
balsa sheet, cut two pieces 10-1/2" [267mm] in length.
❏
2. Using the plan as your guide, cut and shape
each of them to match the shape of the elevator
shown on the plan.
❏
3. Pin the elevator halves to the plan. Locate and
test fit the 1/4" x 3" [6 x 75mm] dowel in place in the
cut-outs on the LE of the elevator. When you are
satisfied with the fit of the dowel, glue it in place with
6-minute epoxy.
