Great Planes PT-E Trainer Electric Kit - GPMA0110 - Manual (Page 17)

D 3 Lay the fin and stabilizer on the plan and mark
the hinge locations on the trailing edges.
D 4 Now, while holding the elevators in place against
the stabilizer trailing edge, transfer the hinge loca-
tions over to the elevator leading edge Repeat this
process to mark the hinge locations on the rud-
der.
NOTE: The hinges supplied with this kit are thin enough
that they can be inserted into a slot made with an Xacto
knife Most other hinges require you to use a hinge slotting
tool The following steps describe how to easily cut the
hinge slots with an Xacto knife.
D 7 After you have cut about halfway into the wood,
you can push the blade all the way through, while
"wiggling" the knife handle back and forth Con-
tinue to pivot the knife while moving the blade to
both ends of the hinge location.
D 8 Trial 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.
D 9 Repeat the above process to cut slots at all the
hinge locations in the fin, rudder, stabilizer and
elevators.
D 10 Assemble the rudder to the fin and the elevators
to the stabilizer (DO NOT GLUE), and check the
operation of the hinges
D 11 Cut off the portion of the bottom rudder hinge
that protrudes in front of the 3/16" x 3/8" fin trailing
edge Note: Be sure to use this hinge in the same
location later when making the final assembly
TEMPORARILY MOUNT CONTROL HORNS
D 1 You'll need Two nylon control horns, four 2-56
x 3/8" machine screws, a 3/32" drill and a small
screwdriver
D 5. Begin by carefully cutting a very shallow slit in
the fin trailing edge at the hinge location 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!
D 6 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.
