BUILD THE TAIL SURFACES

Build the Stabilizer

1. Unroll the plan sheets. Roll them inside out so they will
lie flat.
2. Position the fuse plan so the stab plan is over your flat
building board. Cover the plan with Great Planes Plan
Protector or wax paper so glue will not adhere.
3. From one of the 3/16" x 3/8" x 24" [4.8mm x 9.5mm x
609.6mm] balsa sticks, cut the stabilizer trailing edge and
trailing edge doubler to match the stabilizer plan. Pin the
stab TE over the plan and glue the doubler to the front of the
trailing edge.
4. Pin the die-cut 3/16" [4.8mm] balsa stabilizer leading
edge (S1) in position. Trim and fit the 3/16" x 3" x 2-1/2"
[4.8mm x 76.2mm x 63.5mm] balsa stabilizer center
between the die-cut LE and the trailing edge doubler. Glue
the stab center to the LE and to the front of the stab TE
doubler.
5. Pin the two die-cut 3/16" [4.8mm] balsa stab frames
(S2) in position. Glue the frames to the leading edge S1 and
the stab TE.
6. From the 3/16" x 3/16" x 30" [4.8mm x 4.8mm x
762mm] balsa stick, cut and glue the stab ribs to the stab
frame.
7. Remove the stab from your building board. Inspect all
the glue joints and add CA to any joints that don't look
strong. Fill any gaps with balsa sanding dust and a drop or
two of thin CA.

Build the Elevator

1. From a 3/16" x 3/8" x 24" [4.8mm x 9.5mm x 609.6mm]
balsa stick, cut the elevator leading edge to length and pin
it over the elevator plan. Pin and glue the die-cut 3/16" balsa
elevator frames E-3 through E-5 to the LE.
