DRILL A 3/32" HOLE
1/2" DEEP, IN CENTER
OF HINGE SLOT
CUT HINGE SLOT
WITH HOBBY KNIFE
AND #11 BLADE
D. Use a hobby knife with a #11 blade to
make the hinge slots.The first cut should
be a shallow slit to establish the hinge
slot location. After the first cut make
several more cuts, going slightly deeper
each time. Move the knife from side to
side and widen the slot as you cut.
E. Test join the elevators to the stab with the
hinges in place. DO NOT glue until later.
R Perform the same process for the rudder
ailerons and flaps.
B. Drill a 3/32" hole in the center of all the
hinge slots to allow the CA to fully
penetrate. This is best done with a high-
speed tool such as a powered hand tool.
If you use a drill, remove slivers of balsa
wood from the hinge slots with a hobby
knife after you drill the holes.
TEMPORARY PIN
TO KEEP HINGE
CENTERED
AFTER you have completely covered and
finished you model, perform the following:
A. Use your hobby knife and a sharp #11
blade to remove a small strip of covering
from the hinge slots to expose them.
C. Join the elevator to the stab with the
hinges. If the hinges will not stay
centered, insert a pin through the center
of the hinge, then join the surfaces and
remove the pins.
D. Confirm that the ends of the elevator
align with the ends of the stab, that the
hinges are centered and there is
approximately a 1/32" gap between the
TE of the stab and the LE of the elevator.
A small gap is desirable so you do not
inadvertently glue the elevator to the stab
with residual CA.
E. Carefully apply 6 drops of thin CA to each
side of all the hinges. Keep a tissue handy
