3. Fuselage Assembly: Construct the fuselage frame. Pay close attention to alignment for proper flight characteristics. The cabin is designed with magnetic absorption for easy access to the power system.
4. Tail Section: Assemble and attach the horizontal and vertical stabilizers.
5. Landing Gear Installation: Install the functional landing gear and aluminum structural bracing.
6. Covering: Apply the yellow covering film to the airframe using a covering iron or heat gun. Ensure a smooth, wrinkle-free finish.
7. Power System Installation (Sold Separately):
   • Install the recommended electric motor (e.g., 2216 980KV) into the motor mount.
   • Mount the Electronic Speed Controller (ESC) and connect it to the motor and battery connector.
   • Install four 9g servos for control surfaces (ailerons, elevator, rudder).
   • Connect servos to the receiver (4+ channel radio system required).
   • Install the propeller (9-10 inch recommended) onto the motor shaft.
   • Secure the flight battery (3S 2200-2800mAh recommended) within the fuselage, ensuring proper Center of Gravity (CG).
8. Final Checks: Verify all connections, control surface movements, and CG before the first flight.

5. Operating Instructions

Before operating your Piper Cub J3, ensure you are familiar with the controls of your radio transmitter and have performed all pre-flight checks.

5.1 Pre-Flight Checklist

• Verify all control surfaces (ailerons, elevator, rudder) move freely and in the correct direction relative to stick input.
• Ensure the flight battery is fully charged and securely installed.
• Check that the propeller is securely attached and free from damage.
• Confirm the Center of Gravity (CG) is within the recommended range.
• Perform a range check of your radio system.
• Inspect the flying area for any potential hazards.

5.2 Takeoff

Place the aircraft on a smooth, level surface facing into the wind. Gradually increase throttle while applying slight up-elevator to lift the tail. Once sufficient speed is gained, gently apply more up-elevator to lift off. Maintain a steady climb rate.

5.3 Flight Controls

• Throttle: Controls motor speed and altitude.
• Elevator: Controls pitch (nose up/down).
• Ailerons: Controls roll (wing tilt) for turns.
• Rudder: Controls yaw (nose left/right) for coordinated turns and ground steering.

5.4 Landing

Approach the landing strip into the wind. Reduce throttle gradually to control descent rate. Maintain sufficient airspeed to avoid stalling. As the aircraft nears the ground, gently apply up-elevator to flare and touch down smoothly on the main landing gear, then allow the tail wheel to settle.

6. Maintenance

Regular maintenance ensures the longevity and safe operation of your model aircraft.

• Post-Flight Inspection: After each flight, inspect the airframe for any damage, loose connections, or wear. Check control surfaces, linkages, and landing gear.
• Cleaning: Keep the aircraft clean from dirt, grass, and debris. Use a soft cloth to wipe down surfaces.
• Battery Care: Store batteries in a cool, dry place at storage voltage. Do not leave batteries fully charged or fully discharged for extended periods.
• Propeller Check: Regularly inspect the propeller for cracks, nicks, or bends. Replace damaged propellers immediately.
• Motor and ESC: Ensure the motor spins freely and the ESC connections are secure. Monitor for any unusual heat or noise during operation.
• Covering Film: Periodically check the covering film for wrinkles or tears. Re-tighten with a covering iron on low heat if necessary.
