D 9. While holding an aileron against the inside edge of
the wing center TE, draw a line on it that matches the
inside edge of the wing tip TE. Cut the aileron 1/8" shorter
than the TE opening to allow for covering material.
D 13. Sand the forward edges of the ailerons to a "V".
Refer to the cross section of the wing on the plans for the
desired angle.
D 14. Refer to the plans, then mark the location of the
aileron's hinges. Without using glue, temporarily install
the hinges using the same method as when you installed
the rudder and elevator.
D 10. Hold the aileron in position, centered in the aileron
opening, then mark the location of the torque rod arms.
Extend your marks to the front edge of the aileron.
D 11. Draw a centerline along the entire front edge of the
aileron. Drill a 1/8" hole 3/4" deep into the center of your
"torque rod" mark to accept the torque rod arm.
D 12. Cut a groove from the hole you drilled to the inboard
edge of the aileron. HINT: Using a hobby knife, sharpen the
inside of one end of a 1/8" diameter brass tube, then use it
to cut the groove in the leading edge of the aileron.
D 15. Carefully "crack" the die-cut 1/16" ply TE plate
along its scored centerline. Try not to break the piece in
two. Fit the TE plate on top of the wing at the TE on the
centerline. If needed, sand the edges to fit flush with the
sides and rear of the center wing TE. Use 6-minute epoxy
to glue it in position.
D 15. Cut a 2-1/2" long LE wing dowel from one of the
5/16" x 6" hardwood dowels. Round off both ends
slightly. Use a thin stick to apply 6-minute epoxy to the
inside of the slot in rib R-1 and the hole in the LE. Insert
the wing dowel through the LE into the slot in R-1 and
allow the epoxy to cure.
D 16. Use a 5/16" drill to angle the hole in F-2
downward to match the angle of the wing dowel. Test fit
the wing in the wing saddle. It must sit flat on top of the
fuse — if not, elongate the hole in F-2 slightly, until a
good fit is obtained.
