Section 1. Assembling The Wing - Hangar 9 J-3 Piper Cub Instruction Manual

Section 1: Assembling the Wing
Parts Needed
• Right wing panel with aileron and hinges
• Left wing panel with aileron and hinges
Note: The control surfaces, which include the ailerons, ele-
vator and rudder, come with the hinges installed, but
the hinges are not glued in place. It's imperative that
you use a high-quality, thin CA glue to properly
adhere the hinges and control surfaces in place.
Step 1. The wing is made up of a left and right panel with the
ailerons temporarily mounted in place. You will glue them in
place in later steps in this section. Note that each aileron is con-
trolled by its own servo. You will need two servos when you
begin Section 2.
Step 2. Carefully remove one of the wing panels from its pro-
tective plastic. Remove the aileron from the wing panel. Note the
position of the hinges. The J-3 Cub comes with, four high-
quality hinges in each wing panel.
Step 3. Remove each hinge (4) from the wing panel and insert a
T-pin near the center of the hinge as shown below.
Tools and Adhesives Needed
• Instant thin CA glue
• CA remover/debonder
• Paper towels
• T-pins (one for each hinge)
Step 4. Slide each hinge into the wing panel until the T-pin is
snug against the wing. This procedure is suggested to ensure
each hinge is positioned so an equal portion of the hinge is in
each (i.e., half in the wing and half in the aileron).
Step 5. Slide the aileron onto the wing until there's only a slight
gap (1/32"). The hinge is now centered on the wing panel and
aileron. Remove the T-pins and snug the aileron against the wing
panel, so the aileron is free to move and does not bind.
