some left over tail wood). Glue the scrap piece of wood to the LE
of the Flap/Inner TE to add 1/4" to the TE. Sand the scrap piece
to match the contour of the TE.
D D 8. Sand the TE piece to fit against the sub TE and root
cap without bending the root cap. It is OK to cut a relief groove
in the TE piece if the torque rod is holding it out slightly. Align
the TE piece with the root cap and glue it in place, but do not get
glue on the torque rod itself. Sand the TE piece flush with the top
and the bottom of the wing. Cut a notch in the TE piece to allow
the torque rod to rotate backwards.
photo. Sand the LE'S to blend in with the ailerons/flaps and
round off the corner as shown in the inset.
Round off corner
D D 2. Determine the length of the flap by measuring be-
tween the stationary TE piece and the polyhedral joint on each
wing panel. Deduct 3/16" from the measurement and cut the flap
to this length.
D D 9. Make sure you can sec the pinpoint punch on the top
of a 1/16" Ply Rear Wing Bolt Plate (SPT1W11). If not stick a
pin through the punch mark. Sand the "outside" top edges of the
Rear Wing Bolt Plate to a taper as shown in the photo. Glue it in
place so the rear is flush with the back of the TE and the side is
flush with the root cap. Sand the inside edge to match the dihedral
angle of the root cap. D D 3. Position the flap against the sub TE so there is a
3/32" gap between the end of the flap and the stationary TE.
Adjust the torque rod so the threaded part is centered in the
groove you cut earlier. Trace around the unthreaded end of the
torque rod on the bottom of the flap.
NOTE: The hinge " Gap" will be on the top of the flap.
AILERON/FLAP ASSEMBLY
D D 1. Locate the 1/4" Balsa Aileron/Flap LE
(SPT1W17) and glue it to the front of each aileron and each
flap. Lay the ailerons and flaps flat on the work surface and
glue the LE in place with the "point" up as shown in the
D D 4. Remove the flap and drill a 1/8" hole where you drew
the outline. The hole should just touch me bottom surface of the
flap and should be approx. 1-1/4" deep.
