Great Planes F-15 Eagle 40 Kit - GPMA0438 - Manual (Page 40)

D 4. Clean the torque rods and bearing tubes
with alcohol. Slide the plastic bearings toward the
threaded end of the torque rods, then use a
toothpick to apply a small amount of petroleum
jelly to the ends of the plastic tubes (to help
prevent glue from getting inside and locking up the
torque rods).
D 2. Draw an accurate centerline along the LE
of the tapered balsa ailerons and the wing TE.
D 5. Use epoxy to glue the plastic bearing tubes
into the grooves in the center TE. Make sure the
torque rods are fully seated in the groove, wipe off
any excess glue and allow it to harden. Notice
that there is a right and a left torque rod. Be
sure to assemble them as shown in the photo.
D 6. Sand the TE of the wing to make it straight
with square edges.
D 3. Lay the ailerons in place in their respective
openings, with the torque rods resting on top of the
ailerons. Mark the torque rod locations on the
top of the ailerons.
D 4. Drill a 1/8" hole in the ailerons at the
torque rod locations, starting at the leading edge
centerline and drilling straight in to the proper
depth.
D 7. Carefully glue the center TE to the wing so
the torque rods are exiting the bottom of the wing.
The slot you cut earlier should allow the center TE
to fit the dihedral. Make sure the center TE is
properly aligned with the wing and is not tilted up
or down. Also be careful not to get any glue on the
torque rod wires.
D 5. Use the sharpened 1/8" diameter brass
tube to cut a groove in the leading edge of the
ailerons to accept the torque rods. Trial fit the
ailerons onto the torque rods and cut or file the
groove as necessary until they fit.
ASSEMBLE AILERONS
NOTE: Do not glue the aileron hinges
until after your model has been
covered.
D 1. Cut the tapered ailerons (F154W12) to fit
between the center TE and the tips with a 1/16"
gap on each end. Mark the inside end of each
aileron with an "L" for the left one and an "R" for
the right one.
D 6. Lay the ailerons on the plan and mark the
hinge locations on the ailerons. Place the
ailerons against the wing TE and transfer the
marks over to the wing.
D 7. Cut the hinge slots in the ailerons and wing
TE using a hobby knife, following the procedure
and cautions on page 9.
