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. From two of the straightest 1/4" x 1/2" x 24" [6mm x
13mm x 610mm] balsa sticks, cut the stabilizer leading
and trailing edge to match the stabilizer plan. Pin the leading
and trailing edge over the plan.
❏
4. From 1/4" x 1/4" x 30" [6mm x 6mm x 762mm] balsa
sticks, cut and glue the stabilizer ribs between the leading
and trailing edge.
❏
5. Locate the four die-cut 1/8" [3mm] balsa S3 stabilizer
tips. Make two sets of S3’s by gluing two of the 1/8" [3mm]
S3’s together to make 1/4" (6mm) thick S3’s.
❏
6. Glue the S3 stabilizer tips to the trailing edge of the
stabilizer.
❏
7. Locate the four die-cut 1/8" [3mm] balsa S1 and S2
stabilizer tips. Glue two of the S1’s together and two of the
S2’s together to make two 1/4" (6mm) thick S1’s and S2’s.
❏
8. Pin S1 to the stabilizer tip plan. Pin and glue S2 to S1.
❏
9. From the 1/4" x 3" x 5" [6mm x 76mm x 127mm] balsa
sheet, cut two stabilizer joiners as shown on the stabilizer
plan. Glue the joiners to S2. The stabilizer tips will be glued
to the stabilizer later when the main booms are attached to
the wing.
