Before beginning the assembly of your J-3 Cub, remove each part from its bag for inspection. Closely inspect the
fuselage, wing panels, rudder, and stabilizer for damage. If you find any damaged or missing parts, contact the place of
purchase.
If you find any wrinkles in the covering, use a heat gun or covering iron to remove them. Use caution while working
around areas where the colors overlap to prevent separating the colors.
This manual is divided into sections to help make assembly easier to understand, and to provide breaks between each
major section. Remember to take your time and follow the directions.

In that Horizon Hobby has no control over the final assembly or material used for the final assembly, no liability shall be
assumed nor accepted for any damage of or caused by the final user-assembled product. By the act of using the product,
the user accepts all resulting liability.

Required Parts
• Fuselage • Receiver
Required Tools and Adhesives
• Phillips screwdriver • Hobby knife
 Step 1
Plug the elevator, rudder and throttle servo leads into your
receiver. Plug the "Y" harness into the aileron channel of
the receiver. Plug the switch harness and battery leads
into the receiver as well. Install the flat radio foam into the
fuselage, followed by the die-cut foam.
Note: There is a tube located under the
elevator servo for the antenna wire. Route the
wire through this tube to the tail of the aircraft.
 Step 2
Place the remaining flat radio foam over the receiver and
battery. Secure the foam to prevent the receiver and battery
from moving from their location.
Note: The windows are not show for clarity.

Required Tools and Adhesives
• Phillips screwdriver (small)
 Step 1
Attach the propeller following the instructions provided
with your engine.
Note: Photo is shown using an acorn
nut installed instead of the standard propeller
nut and washer.
 Step 1
Position the landing gear to the bottom of the fuselage.
Secure the position of the gear using four landing gear
straps and eight 3mm x 10mm screws.

Required Parts
• Stabilizer assembly • Fuselage
• #4 washer (4)
• 4-40 x 1/2" socket head screw (4)
Required Tools and Adhesives
• Hex wrench: 3/32" • Threadlock
 Step 1
Slide the stabilizer halves into the slot in the fuselage.
Use four 4-40 x 1/2" screws and four #4 washers to
secure the stabilizer. Use threadlock to prevent the
screws from vibrating loose during flight.
 Step 2
Attach the elevator clevises to the elevator control horns.
 Step 8
Attach the four connectors to the brass fittings of the
stabilizer. The cables should have very light tension.

Required Parts
• Wing • Fuselage
• 4-40 lock nut (16) • 4-40 nut (4)
• Strut support anchor (4) • Strut bracket (4)
• Strut end (4) • Strut (narrow) (L&R)
• Strut (wide) (L&R) • Strut brace (long) 2
• Strut brace (short) (2) • Strut cross brace (2)
• #2 x 3/8" screw (4) • Fuselage hatch
• 1/4-20 x 2" nylon bolt (2)
• 4-40 x 1/2" socket head screw (24)
Required Tools and Adhesives
• Hex wrench: 3/32" • Adjustable wrench
• Threadlock
• Phillips screwdriver (small)
  Step 1
Attach two strut brackets to the bottom of the wing using
four 4-40 x 1/2" socket head screws. Use threadlock to
prevent the screws from loosening during flight.
  Step 2
Thread the strut support anchors into the holes in the
wing. The anchors have external threads.
  Step 3
Attach the strut to the strut brackets using two 4-40 x 1/2"
socket head screws and two 4-40 lock nuts. The wide strut
goes towards the leading edge, the narrow strut towards
the trailing edge.
Note: The airfoil of the struts matches the
direction of the wing. The struts also have
fittings in the center, which will face towards
the wing when installed.

  Step 4
Thread a 4-40 nut onto the threaded end of the strut.
Thread a strut end onto the strut. The nut will be used
once the strut has been adjusted.
  Step 5
Install the short strut brace to the rear strut support
anchor and the long strut brace to the front strut support
anchor using 4-40 x 1/2" socket head screws and
4-40 nuts. Attach the strut supports and the strut cross
brace using two 4-40 x 1/2" socket head screws and
two 4-40 lock nuts.
  Step 6
Slide the wing tube into the wing panel. Slide the tube and
panel into position on the fuselage.
  Step 7
Secure the wing panel using a 1/4-20 x 2" nylon bolt.
Step 5 Photo
Section 5: Wing Installation

  Step 8
Support the fuselage so the wing is not resting on the
work surface. Adjust the strut end so it aligns with the
wing strut mount. Attach the wing struts using two
4-40 x 1/2" socket head bolts and two 4-40 locking
nuts. Once attached, tighten the 4-40 nuts on the strut to
prevent the end from rotating when the wing is removed
for storage.
 Step 9
Repeat Steps 1 through 8 to install the remaining wing
panel and strut.
 Step 10
Install the fuselage hatch using four #2 x 3/8" screws.
Note: When removing the wing, simply
disconnect the bolts holding the strut to the
fuselage. This will make things much easier
when installing the wing at the field.
Note: The struts on the J-3 Cub are
functional, so be sure all bolts and nuts
are tight before flying. Failure to do so
could result in wing failure.
 Step 1
Completely read the instructions included with your
engine and follow the recommended break-in procedure.
 Step 2
At the field, adjust the engine to a slightly rich setting at
full throttle and adjust the idle and low-speed needle so
that a consistent idle is achieved.
 Step 3
Before you fly, be sure that your engine idles reliably,
transitions and runs at all throttle settings. Only
when this is achieved should any plane be considered
ready for flight.
