2. Safety Information

Operating a remote-controlled aircraft requires caution and adherence to safety guidelines to prevent injury or damage. This model is intended for teenagers, young adults, and adults. It is not a toy.

• Always operate in open areas: Choose a large, clear flying field away from people, buildings, trees, and power lines.
• Maintain visual contact: Always keep the aircraft in sight and do not fly beyond your visual range.
• Check weather conditions: Do not fly in strong winds, rain, or other adverse weather.
• Battery safety: Use only recommended LiPo batteries and chargers. Never overcharge or discharge batteries. Store batteries in a safe, fireproof location. Disconnect the battery from the aircraft when not in use.
• Propeller/Impeller safety: The impeller jet can cause severe injury. Keep hands, face, and loose clothing away from the impeller when the battery is connected.
• Pre-flight checks: Before each flight, ensure all control surfaces move correctly, the battery is fully charged, and the transmitter is functioning properly.
• Respect local regulations: Be aware of and comply with all local laws and regulations regarding RC aircraft operation.

3. Package Contents

The Amewi AMXFlight L-39 Albatros is a Plug-N-Play (PNP) model, meaning the main components are pre-installed. Please inspect the package contents upon receipt to ensure all items are present and undamaged.

• AMXFlight L-39 Albatros aircraft body (with pre-installed motor, ESC, and servos)
• Wing set
• Horizontal and vertical stabilizers
• Landing gear set
• Small parts bag (screws, pushrods, etc.)
• Instruction Manual

Items required for operation (not included):

• 6-channel 2.4GHz RC transmitter and receiver
• 3S 11.1V LiPo battery (with XT60 connector)
• Compatible LiPo battery charger

4. Assembly

As a PNP model, the assembly of the L-39 Albatros is straightforward. Follow these steps carefully:

1. Wing Installation: Carefully slide the main wings onto the fuselage. Secure them using the provided screws or locking mechanism as indicated in the diagrams (refer to specific diagrams in the printed manual for detailed steps). Ensure the wing wires are connected to the appropriate servo leads inside the fuselage.
2. Tail Assembly: Attach the horizontal and vertical stabilizers to the rear of the fuselage. Ensure they are correctly aligned and secured. Connect the elevator and rudder pushrods to their respective control horns and servos.
3. Landing Gear: Install the main landing gear and nose gear. Ensure they are firmly seated and can withstand landing forces.
4. Receiver Installation: Mount your 2.4GHz receiver securely inside the fuselage, away from the ESC and motor wires to minimize interference. Connect the servo leads from the wings and tail to the corresponding channels on your receiver.

Double-check all connections and ensure all screws are tightened before proceeding to setup.

5. Setup

Proper setup is crucial for safe and stable flight.

1. Transmitter Binding: Follow your transmitter's instructions to bind it with your receiver. Ensure a solid connection is established.
2. Control Surface Check: With the transmitter and receiver powered on, and the flight battery connected (impeller clear!), verify that all control surfaces (ailerons, elevator, rudder) move in the correct direction relative to your stick inputs. Adjust servo reverse settings on your transmitter if necessary.
3. Control Throws: Set appropriate control throws (the amount of movement for each control surface) on your transmitter. Start with recommended low rates for initial flights and adjust as you gain experience.
4. Center of Gravity (CG): The correct CG is critical for stable flight. Refer to the specific CG location marked on the underside of the wings or specified in the detailed manual. Adjust the battery position within the fuselage to achieve the recommended CG. A nose-heavy aircraft will be more stable but less agile; a tail-heavy aircraft will be unstable and difficult to control.
5. ESC Calibration: If required, calibrate the Electronic Speed Controller (ESC) with your transmitter's throttle stick. Consult the ESC manual for specific instructions. The Hobbywing 20A ESC is pre-installed.

6. Operating

Before your first flight, ensure you are familiar with basic RC flight principles and have practiced on a simulator if possible.

1. Pre-Flight Checklist:
   • Battery fully charged and secured.
   • Transmitter battery charged.
   • Control surfaces move freely and correctly.
   • All connections secure.
   • Flying area clear and safe.
2. Take-off: Hand launch the aircraft into the wind with a firm, level throw at approximately 75-100% throttle. Alternatively, if equipped with functional landing gear, perform a smooth take-off from a suitable runway. Gradually increase throttle and apply gentle elevator input to lift off.
3. Flight Controls: Use the ailerons for roll, elevator for pitch (climb/dive), and rudder for yaw (directional control). Coordinate these controls for smooth maneuvers.
4. Landing: Approach the landing area into the wind. Reduce throttle gradually and maintain sufficient airspeed to avoid a stall. Gently flare (pull back on the elevator) just before touchdown to reduce speed and achieve a soft landing.
5. Post-Flight: Disconnect the flight battery immediately after landing. Inspect the aircraft for any damage.

7. Maintenance

Regular maintenance will extend the life of your AMXFlight L-39 Albatros.

• Cleaning: Wipe down the aircraft with a soft, damp cloth after each flight to remove dirt and debris. Avoid using harsh chemicals.
• Damage Inspection: Regularly check the EPO foam airframe for cracks or dents. EPO foam is easy to repair using foam-safe glues. Inspect control surfaces, hinges, and pushrods for wear or damage.
• Motor and ESC: Ensure the motor spins freely and there are no obstructions in the impeller. Check the ESC for any signs of overheating or damage.
• Battery Care: Store LiPo batteries at a storage voltage (approximately 3.8V per cell) when not in use for extended periods. Do not store fully charged or fully discharged.
• Storage: Store the aircraft in a cool, dry place, away from direct sunlight and extreme temperatures.
