Warning An RC aircraft is not a toy! If misused, it can cause serious bodily harm and damage to property. Fly only in open areas, preferably at AMA (Academy of Model Aeronautics) approved flying sites, following all instructions included with your radio and engine.
Using the Manual 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. Before Starting Assembly 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.
Section 1: Receiver Installation Required Parts • Fuselage Step 2 • Receiver Required Tools and Adhesives • Phillips screwdriver • Hobby knife 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. 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.
Section 2: Landing Gear Installation Required Parts • Landing gear w/wheels • Landing gear strap (4) • 2mm x 14mm screw (8) 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.
Section 4: Installing the Stabilizer Required Parts • Stabilizer assembly • Fuselage • #4 washer (4) • 4-40 x 1/2" socket head screw (4) Step 2 Attach the elevator clevises to the elevator control horns. 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.
Section 5: Wing Installation 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) Step 2 Thread the strut support anchors into the holes in the wing. The anchors have external threads.
Section 5: Wing Installation 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 Photo Step 6 Slide the wing tube into the wing panel. Slide the tube and panel into position on the fuselage. 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.
Section 5: Wing Installation Step 8 Step 9 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. Repeat Steps 1 through 8 to install the remaining wing panel and strut.
Control Throws The amount of control throw should be adjusted as closely as possible using mechanical means, rather than making large changes electronically at the radio. By moving the position of the clevis at the control horn toward the outermost hole, you will decrease the amount of control throw of the control surface. Moving it toward the control surface will increase the amount of throw.
Preflight Range Test Your Radio Step 3 Step 1 Double-check that all controls (aileron, elevator, rudder and throttle) move in the correct direction. Before going to the field, be sure that your batteries are fully charged, per the instructions included with your radio. Charge both the transmitter and receiver pack for your airplane. Use the recommended charger supplied with your particular radio system, following the instructions provided with the radio.
Notes: 13
2005 Official AMA National Model Aircraft Safety Code GENERAL 1) I will not fly my model aircraft in sanctioned events, air shows or model flying demonstrations until it has been proven to be airworthy by having been previously, successfully flight tested. 2) I will not fly my model higher than approximately 400 feet within 3 miles of an airport without notifying the airport operator. I will give right-of-way and avoid flying in the proximity of full-scale aircraft.
2005 Official AMA National Model Aircraft Safety Code 5) Flying sites separated by three miles or more are considered safe from site-to site interference, even when both sites use the same frequencies. Any circumstances under three miles separation require a frequency management arrangement, which may be either an allocation of specific frequencies for each site or testing to determine that freedom from interference exists.
