4. Cut the right wing tip loose from the wing and use
a Dremel Moto Tool to hollow out the wing tip. (This will
help to compensate for the weight of the engine head and
muffler).
5. Now securely glue the right wing tip in place.
Cut 2" off Aileron stock
and glue permanently to TE
6. Cut 2" off one end of the tapered ailerons and glue
the 2" pieces permanently to the trailing edge as shown in the
sketch. This moves the aileron away from the turbulence
caused by the tip vortex. Make sure you carefully line up this
piece with the top and bottom surfaces of the wing.
to make room for the torque rod bearings. Trial fit the ailerons
onto the torque rods and cut or file as necessary until they fit.
6. Lay the ailerons on the plan and mark the hinge
locations on the ailerons. Use two hinges near the tips. Place
the ailerons against the wing TE and transfer the marks over
to the wing.
7. Cut the hinge slots in the ailerons and wing TE using
an Xacto knife or hinge slotting tool.
8. IMPORTANT! Condition or "break-in" the hinges
INSTALL AILERONS
NOTE: Do not glue the aileron hinges until after your model
has been covered.
by folding them back and forth several times,
"V"-shape as shown on the wing rib detail drawing.
9. Sand the leading edge of the ailerons to the same

aileron openings and trim the ailerons as necessary. You
should provide approximately 1/16" gap at each end of the
ailerons.
There should be no hinge gap!
11. Now is a good lime to finish the wing tips. Tape the
ailerons on in the neutral position, and sand the wing tips to
blend with the ailerons.
INSTALL WING DOWELS
3. Lay the ailerons in place in the openings, with the
torque rods resting on lop of the ailerons. Mark the torque
rod locations on the top of the ailerons.
4. Drill a 7/64" hole in the ailerons at the torque rod
locations, starting at the leading edge centerline and drilling
straight in to the proper depth. (The hole is drilled slightly
oversize to allow for positioning, and to create a hard epoxy
"sleeve" around the wire).
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. Cut these grooves a little larger at the beginning,
1. Mark a horizontal centerline on the flat which you
sanded on the wing LE. Also mark a vertical centerlineon the
die-cut 1/8" ply former F-2A (the Wing Dowel Plate).
