Great Planes ESP6 Easy Sport 60 - GPMA0152 - Manual (Page 10)

D 1 In the same manner as the rudder, build each
elevator using the 5/16" x 3/4" and 5/16" x 1/2"
balsa sticks
D 2. Shape the elevator tips to the shape as shown on
the plan.
D 3. Carefully draw a centerline all around the edges
of the elevators.
D 4. Sand the leading edge to a "V-shape Sand the
trailing edge and the outside edge of the tip to a round
shape as shown on the plans.
D 6 Trial fit the joiner wire into the elevators Then
glue it in using 6-minute or 30-mmute epoxy When
gluing, lay the elevators on a flat surface, with the
leading edges along a straightedge to insure perfect
alignment Cover the top of the joined elevators with a
sheet of waxed paper Then lay a flat, heavy object on
top A telephone book works well This will insure a true,
flat elevator assembly when the epoxy cures
(Do not glue)
D 1 Temporarily pin the elevators and stab over their
respective drawings on the plan
D 2. Lay the 1/8" wire elevator joiner in place on the
elevators and mark its outline using a fine point felt-tip pen
D 1. Cut 18 hinges (3/4" x 1") from the 2" x 9" CA hinge
strip Trim the corners at a 45 degree angle to make
insertion easier.
D 2 Lay the rudder and elevators on the plan and mark
the hinge locations. Place the rudder against the fin TE
and transfer the marks to the fin Place the elevators
against the stab TE and transfer the marks to the stab.
D 3 Accurately drill holes in the elevators for the 1/8"
wire joiner Begin by drilling a 1/16" or 5/64" pilot hole
Then drill the final hole to a depth of 7/8" with a 9/64"
drill bit (The hole is drilled slightly oversize to allow for
positioning, and to create a hard epoxy "sleeve" around
the wire)
D 4 Use the sharpened 1/8" diameter brass tube or a
drill bit to cut a groove in the leading edge of the
elevators to accept the joiner wire.
CAUTION: You must use extreme care when
cutting hinge slots with a hobby knife, to avoid
cutting yourself! If the balsa part breaks while you
are pushing on the knife, the blade could go into
your hand before you know it! A good precaution
is to wear leather gloves while performing the
following steps, and always cut away from
yourself.
D 5 Roughen the joiner wire with coarse sandpaper,
then clean the wire thoroughly with alcohol to remove
any oily residue.
D 3. Cut the hinge slots on the accurate centerlines
which you previously drew, using a hobby knife or a
slotting fork and slotting hook (The recommended hinge
slotting technique is explained on the next page.)
