2. Place the center TE's over the wing plan and mark the
location of the aileron torque rods. Cut notches at the
marks to clear the torque rods. Test fit the torque rods to
make sure the notches allow enough clearance.
❏
3. Position the center TE's on the wing TE with the
torque rods installed, then mark the location of the notches
on the wing TE. Cut the notches in the wing TE at the
marks you made. Test fit the center TE's with the torque
rods to make sure the notches align and are large enough
to allow for proper aileron deflection.
❏
4. Use coarse sandpaper to scuff the nylon tube
bearings on the aileron torque rods so the glue will stick.
❏
5. Use 30-minute epoxy to simultaneously glue the nylon
bearing tubes in the center TE's and glue the center TE's to
the wing. IMPORTANT: Before gluing, use a tooth pick to
apply a dab of petroleum jelly to the ends of the nylon tubes
to keep the epoxy out.Tape the TE's edges to the wing until
the epoxy cures. Wipe away excess epoxy before it cures
and do not let epoxy get into the nylon bearing tubes.

6. Position the left aileron on the trailing edge of the
wing, then mark the location of the torque rod. Using a
straightedge, mark the end of the aileron where it meets the
wing tip.
❏ ❏
7. Cut the aileron approximately 1/16" shorter than
the mark you made at the tip so it will fit in the wing.
❏ ❏
8. Use a draftsman's square to extend the torque rod
marks to the front of the aileron, then use the "centerline
technique" we've shown you before to mark the centerline
on the entire leading edge of the aileron.
❏ ❏
9. Use the centerline and the marks you made earlier
as a guide to drill a 1/8" hole, 3/4" deep in the aileron for the
torque rod.
❏ ❏
10. Refer to the Expert Tip that follow, then cut a 1/8"
groove in the leading edge of the aileron.
HOW TO CUT A GROOVE FOR AILERON TORQUE ROD
A. Use a #11 knife blade to sharpen the inside end of a
piece of 1/8" brass tube. Roll the tube as you
carve the
end. If you have a file or a cut-off wheel it helps to sharpen
the outside of the end of the tube as well.
