CUTTING THE HINGE SLOTS
Q 1. Lay the rudder and elevator on the plan
sheet and mark the hinge locations. Place the
rudder against the finTE and transfer the marks
over to the fin. Place the elevator against the
stabTE and transfer the marks on to the stab.
I..1 2. To cut the slots for the hinges, use the
following steps:
A. Begin by carefully cutting a very shallow
siit at the hinge position on the centerline.This
first cut is to establish your cut in the right
place, so concentrate on staying on the
centerline and don't cut too deep!
Ql B. Make three or four more cuts in the same
line, going slightly deeper each time. As you
make these additional cuts, work on going
straight into the wood. Continue the process
while "wiggling" the knife handle forward and
backward until the blade has reached the proper
depth for the hinges.
1-.1 C.Test fit the hinge into the slot. If the hinge
is difficult to push in, re-insert the knife and
move it back and forth in the slot a few times to
enlarge the slot.
Q 3. Insert the hinges into the slots and test fit
the rudder and elevator to the fin and stabilizer.
Do not glue the hinges until after you have
covered the model.
Q 2. Use two of the 1/8"x 1/4" x 24" balsa sticks
to make the upper and lower fuse rails. Use
medium CA to glue them into position.Trim the
excess extending past the stabilizer base.
Q 3. Once the glue sets, remove the fuse side
from your building surface. Examine and add
thick CA glue to any open joints, then use your
sanding block or bar sander with medium (150-
grit) sandpaper to sand both sides of the
fuselage side smooth.
Ql 4. Repeat steps 1 through 3 to build another
fuse side.
FUSE SIDE CONSTRUCTION
Q 1. Locate the die-cut 1/8" balsa stabilizer
bases and fuse sides. Drill two 1/4" holes in
the fuselage sides at the punch marks. Pin one
side and one base over their appropriate
locations on the plan.
Q Q 5. Select four of the hardest 1/16" x 3" x
24" balsa sheets to be used for the fuse sides.
Cut a 45° on one of the 1/16" x 3" x 24" sheets.
Use a straightedge to true up the longer edge of
the sheet. Align the bottom fuse rail with the
