4. Cut the stab, elevator, vertical fin and rudder
skin templates from the plan. Use a straightedge
and ballpoint pen to mark their outline onto the 9” x
15” [229 x 381mm] planks (do not use a felt-tip pen).
The templates are slightly oversize to allow slight
variances in construction. Note the grain direction.
Follow this sequence:
(2) planks – stab and rudder.
(2) planks – stab and elevator.
(2) planks – vertical fin and elevator.
BUILD THE STABILIZER
AND ELEVATORS
Build the right and left stab halves simultaneously.
❏
1. Position the plan so the stab is over your flat
building board (or cut the stab from the plan), tape it
down and cover it with waxed paper or Plan Protector.
❏
2. Glue both die-cut 1/8” [3.2mm] balsa LE braces
together and both die-cut 3/32” [2.4mm] balsa S1S
ribs together.
❏
3. Test fit the die-cut 3/32” [2.4mm] balsa stab ribs
S2S through S7S in the notches of both die-cut 1/8”
[3.2mm] balsa stab TE spars (S9). Make a left and
right assembly. Place both assemblies over the plan
and add the LE brace. See the photo at step 4.
❏
4. Use a small square to align the stab TE spar at
rib S2S over the plan. Pin rib S2S over its location on
the plan with a T-pin about 1/4” in front of the TE spar.
Note: The above photo shows S1S in place, but it is
not installed until step 11.
❏
5. Use the same method to align the TE spar and
pin the rest of the ribs on both sides of the stab to
your building board over the plan.
❏
6. Pin the fronts of the ribs to your building board
over the plan.
❏
7. Add both die-cut 1/8” [3.2mm] balsa elevator
LE spars (S8) to the assembly.
❏
8. Make sure all the jig tabs of all the ribs are
contacting your building board. Glue the stab TE
spar and elevator LE spar to the ribs with medium
CA. Don’t use large amounts of CA or build up fillets
of glue. Later we will instruct you to reinforce glue
joints that don’t look strong.
Beech Fact: In 1946 Walter H. Beech announced
his all new, revolutionary, single engine entry in the
postwar market. He named it the Bonanza,
descriptive of an extra value offered in the way of
economy, performance and pleasure to the owner.
