BUILD THE ELEVATORS
❏ ❏ 1. Place the die-cut 1/8" [3.2mm] balsa elevator
base over the plan. Mark the locations of the “ribs” on
both sides of the base.
❏ ❏ 2. From the grooved 11/16" x 11/16" x 18" balsa
control surface LE, cut a piece to the length shown on
the plan.
❏ ❏ 3. Glue the elevator base into the slot in the control
surface LE, perpendicular to the slot. Hint: An easy
method of accomplishing this is by inserting the aft edge
of the elevator base in a remaining piece of LE (do not
glue it to the elevator base) and holding both pieces of
LE against your building board while gluing.
❏ ❏ 4. Position the elevator with the LE hanging over the
edge of the table. Use the 1/8" x 9/32" x 30" balsa sticks
to make the elevator ribs gluing them to the elevator at
the marks you made previously.
❏ ❏ 5. Cut and glue the elevator ribs to the other side of
the elevator base.
❏ ❏ 6. From the 1/8" x 1" x 30" balsa stick, cut and glue
the balance tab base, centered on the LE of the elevator,
at the location shown on the plan.
❏ ❏ 7. Sand the end of the elevator base, LE and balance
tab base even. Cut the elevator tip from a 5/8" x 3/4" x 6"
balsa stick and glue it to the elevator outboard end, centered
on the end of the elevator base, LE and balance tab.
❏ ❏ 8. Sand the front of the balance tab base and
elevator tip even. Cut a 3" [76.2mm] long balance tab LE
from a 3/8" x 3/4" x 12" balsa stick. Glue the LE to the
front edge of the balance tab and elevator tip.
❏ ❏ 9. Cut a balance tab root cap rib from the remaining
1/8" x 1" balsa stick. Glue it to the root end of the balance
tab. Glue a 1/8" x 9/32" rib to both sides of the balance tab
at the location shown on the plan.
❏ ❏ 10. From the 3/8" x 1-1/4" x 6" balsa block, cut a
torque rod block to fit the opening in the elevator base.
Glue the block, centered on the LE, elevator base and ribs.
❏ ❏ 11. Sand the root end of the elevator even. Cut a root
doubler rib from the remaining 1/8" x 1" balsa stick. Glue
the doubler to the root end of the elevator.
Note: We used Robart Large Hinge Points #310 to hinge
the elevators to the stab. If you are using large hinge
points, glue balsa hinge blocks to the elevator at the hinge
locations.
❏ ❏ 12. Sand the tip of the elevator to match the outline
on the plan.
