24. D CUT TAPERED BALSA TRAILING EDGE STOCK

INTO AILERONS, FLAPS AND CENTER

TRAILING EDGE PIECES

Mark and cut the Balsa Stock into three parts as

shown on the plan. Make parts for both wing panels. Even

if you will not have workable Flaps, you still need to cut the
Flap pieces from the stock provided. The Flaps will simply

glue to the wing Trailing Edge later.

D PREPARE THE CENTER TRAILING EDGE PIECES

Groove and notch the Center Trailing Edge pieces

for Flap Torque Rod clearance. Use epoxy and glue the
brass tube only of the torque rods into the groove in the
Center Trailing Edge piece. Make Right and Left pieces.
(The long torque arm goes up when the Center Trailing
Edge pieces are upright.) If you do not want workable
Flaps, there is no need to glue the torque rods into the
Center Trailing Edge pieces. The torque rods will not be used.

26. D GLUE THE CENTER TRAILING EDGE PIECES TO

THE WING PANELS

Sand the Center Trailing Edge Pieces if necessary

and check the fit to the wing panels. Notch out the wing
panel Trailing Edge for Torque arm clearance. Glue in place
using epoxy. Use extreme care when gluing so you do not

glue the torque arms themselves to the Wing Panels.

27. D TEMPORARILY HINGE THE FLAPS AND

AILERONS TO THE WING PANELS

Mark the positions of the hinges on each wing

panel trailing edge and the Flap and Aileron leading edges.
Check the drawings on the plans. The Flaps are Bottom
hinged; the Ailerons are Top Hinged. Cut the slots for both

at the angles shown on the drawings. Mark and drill a hole

in the Flap leading edge for the torque arm. Groove the
Flap leading edge for torque rod clearance. Trial fit the
Flaps and Ailerons. Tack glue the Flaps and Ailerons to the

wing panels and final sand. (If you do not want workable

Flaps, then just glue the tapered Flap to the Wing panel.)
