2. Package Contents

Your Freewing 1026mm Wingspan EPO Delta Wing FPV Flywing RC Airplane KIT package includes:

• 1x Freewing 1026mm Wingspan EPO Delta Wing FPV Flywing RC Airplane Kit (EPO foam airframe)

Note: This is a KIT version. Electronic parts (servo, ESC, battery, motor, radio receiver/transmitter) and glue are NOT included and must be purchased separately.

3. Specifications

Recommended Parts (Not Included):

• Servo: 2*9g
• ESC: 30A
• Battery: 3-4S 1500-2600mah
• Motor: 2208/ 2212 2200KV
• Radio: ≥3CH (Transmitter and Receiver)

4. Setup and Assembly

As this is a KIT, assembly is required. Ensure you have all recommended electronic components and appropriate adhesive (not included) before starting.

4.1 Component Installation

1. Motor Installation: Securely mount the recommended 2208/2212 2200KV motor to the designated motor mount at the rear of the airframe.
2. ESC Installation: Install the 30A ESC in a location that allows for good airflow for cooling, typically within the fuselage or wing. Connect the ESC to the motor and ensure proper wiring for power and signal.
3. Servo Installation: Install the two 9g servos into their respective locations for controlling the elevons. Connect the control rods to the servos and elevons, ensuring free movement.
4. Receiver Installation: Mount your ≥3CH radio receiver securely within the fuselage, ensuring antennas are positioned for optimal signal reception. Connect the servos and ESC to the appropriate channels on the receiver.
5. Battery Compartment: The battery compartment is designed to accommodate a 3-4S 1500-2600mah battery. Ensure your chosen battery fits within the dimensions of approximately 200mm (length) x 100mm (width).

4.2 Center of Gravity (CG)

Proper Center of Gravity (CG) is critical for stable flight. Refer to the markings on the underside of the wing for the recommended CG location. Adjust the position of your battery and other components as needed to achieve the correct balance. The image below illustrates the CG marking.

4.3 Control Surface Setup

Ensure that the elevons move freely and in the correct direction relative to your transmitter inputs. For a delta wing, elevons typically combine the functions of elevators and ailerons. Verify that:

• Moving the elevator stick up causes both elevons to move up.
• Moving the elevator stick down causes both elevons to move down.
• Moving the aileron stick left causes the left elevon to move up and the right elevon to move down.
• Moving the aileron stick right causes the right elevon to move up and the left elevon to move down.

Adjust your radio's mixing settings if necessary to achieve this behavior.

5. Operating Instructions

5.1 Pre-Flight Checks

• Battery: Ensure the flight battery is fully charged and securely installed.
• Control Surfaces: Verify all control surfaces (elevons) move freely and correctly with transmitter inputs.
• CG: Confirm the Center of Gravity is within the recommended range.
• Propeller: Check that the propeller is securely attached and free from damage.
• Environment: Fly in an open area, away from people, obstacles, and power lines. Check local weather conditions for suitable flying.

5.2 Flight

• Launch: Hand launch the aircraft gently into the wind with a slight upward angle, applying about 70-80% throttle.
• Control: Use small, smooth control inputs. Delta wings are typically agile.
• Altitude: Gain sufficient altitude before attempting complex maneuvers.

5.3 Landing

• Approach: Reduce throttle and begin a gradual descent. Aim for a smooth, controlled glide.
• Flare: Just before touching down, gently pull back on the elevator stick to raise the nose slightly and reduce speed for a soft landing.
• Power Off: Once on the ground, immediately cut the throttle.

6. Maintenance

• Post-Flight Inspection: After each flight, inspect the airframe for any damage, cracks, or loose components.
• EPO Repair: Small dents or tears in the EPO foam can often be repaired with foam-safe glue.
• Electronic Connections: Periodically check all wiring and connectors for secure fit and signs of wear.
• Motor and Propeller: Ensure the motor spins freely and the propeller is balanced and undamaged. Replace damaged propellers immediately.
• Storage: Store the aircraft in a cool, dry place away from direct sunlight and extreme temperatures.

7. Troubleshooting

• Aircraft does not respond to controls: Check transmitter battery, receiver connection, and servo connections. Ensure the receiver is bound to the transmitter.
• Aircraft flies erratically/unstable: Re-check Center of Gravity (CG). Verify control surface directions and throws. Inspect for any physical damage to the airframe or control linkages.
• Loss of power during flight: Check flight battery charge level and condition. Inspect motor and ESC connections for loose wires or damage.
• Motor not spinning: Check ESC connection to motor and battery. Ensure ESC is armed and receiving a signal from the receiver.

8. User Tips

• Always perform a range check of your radio system before the first flight of the day.
• Start with small control throws and gradually increase as you become more comfortable with the aircraft's handling.
• Consider using a flight simulator to practice flying before taking your model to the field.
• For FPV flying, ensure your video transmitter and receiver are properly configured and tested before flight.
