❏ 1. Unroll the plan sheets. Roll them inside out so they will
lie flat.
❏ 2. Position the wing 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. Locate the two die-cut 1/8" [3mm] balsa stab braces
(SBR) and two die-cut 1/8" [3mm] balsa stab centers (SC).
Glue the parts together to form the 1/4" [6mm] balsa stab
brace and the 1/4" [6mm] stab center.

stab center (SC) to the balsa stab brace (SBR).

sticks. Cut them to size as shown on the plan to form the stab
outer structure. Pin them to the building board over the
plans. Glue them together forming the stab outer structure.
❏ 6. Locate the 1/4" x 1/4" x 30" [6 x 6 x 750mm] balsa
sticks. Cut them to size as shown on the plan. Then glue
them in place to form the stab inner structure.
❏ 7. Cut the 1/4" x 1/2" x 30" [6 x 13 x 750mm] balsa sticks
to size as shown on the plan. Then glue them in place to
form the elevator outer structure.
