BUILD THE ELEVATORS
D 1. You'll need the following parts: Die-cut 3/16" balsa
elevator ends, 3/16" x 3/8" x 24" balsa stick, 3/16"
x 3/16" x 24" balsa stick, the remaining 3/32" x 3/16"
balsa stick, and the 3/32" wire elevator joiner.
ELEVATOR JOINER WIRE
D 7. Use a pin to start a pilot hole in the elevator
leading edge (on the centerline you previously
marked). The hole will be located in the middle of
the wire outline you drew in the above step. (See
photo).
D 2. Working on waxed paper over the plans, cut the
outer framework pieces and glue them together
and to the die- cut elevator ends.
D 3. Cut the elevator ribs from the 3/32" x 3/16" balsa
stick, and glue in place.
D 4. Sand both sides of the elevators smooth with your
T-bar, then sand the trailing edge and ends to a
rounded shape as shown in the typical cross-section.
D 5. Draw a centerline down the full length of the
elevator leading edge, then use your T-bar to sand
the leading edge to a "V-shape as shown on the
typical cross-section.
D 8. Drill a 7/64" diameter hole into the elevators at
the holes you started in the above step. (Drilling
slightly oversize will permit some adjustment when
joining the elevators).
D 9. Clean all oily residue from the wire elevator
joiner using a tissue dampened with alcohol or a
degreasing solvent. Then roughen the wire with
coarse sandpaper (so the glue will stick to the wire).
D 6. Position the elevators over the plans and lay the
3/32" wire elevator joiner on top of the elevators.
Then use a pen to mark the outline of the wire on
the elevators.
D 10. Use the threaded end of one of the 12" pushrod
wires to "file" a groove in the elevator leading edge.
Make the groove deep enough to fully accept the
joiner wire.
