WING ASSEMBLY
INSTALL THE AILERONS
Use the sketch to help you determine which
side is the top and mark the top side of each
piece. Make another mark 7/16" from the
"inboard" end of each piece. Notch each piece
to make a slot for the torque rod.
Note: The threaded portion of each torque rod
should stick out the top of each wing. Also
there will be a "right" and a "left" center trailing
edge piece so don't make two exactly alike.
Balsa SUB TE 26-1/2" Long
D 1. Locate the two balsa 15/32" x 3/8 x
26-1/2" Sub Trailing Edge pieces (Sub TE).
Trial fit the Sub TE against the trailing edge of
each wing half. The Sub TE should be oriented
as shown in the sketch with the 90-degree
corners along the bottom of the wing. Epoxy
the Sub TE to the trailing edge of each wing
half. Pins or tape can be used to help hold the
Sub TE in place while the glue cures.
Balsa CENTER TE 3-7/8 " Long
D 2. Locate the two balsa 3/8" x 1-1/4" x
3-7/8" tapered center trailing edge pieces.
D 3. Use 150-220 grit sandpaper to roughen
the outer surface of the torque rod bearing.
Slide the bearing toward the threaded end of
the torque rod and put a small amount of
p e t r o l e u m jelly a r o u n d the ends of the
bearing tube to prevent epoxy from seeping
in. Spread some epoxy in the slot and on the
leading edge of the center trailing edge
pieces. Do not apply any epoxy within 1/4" of
the notch or you may glue the torque rod.
Insert the torque rods into the slots with the
threaded portions sticking out through the
notches. Position the center trailing edges
against the wing sub trailing edge. Align the
center trailing edges and pin or tape them in
place while the glue cures.
