2. Installation
Although this is a Ready-To-Fly (RTF) model, some initial steps are required before your first flight. Carefully follow these instructions.
2.1 Chargement de la batterie
The helicopter uses 14.8V 3300mAh 35C Lithium Polymer (LiPo) batteries. Always use the provided charger or a compatible LiPo balance charger. Improper charging can lead to fire or damage.
- Connectez le chargeur à une source d’alimentation.
- Connect the LiPo battery's balance lead to the balance port on the charger.
- Connect the main power lead of the LiPo battery to the charger's output port.
- Select the correct battery type (LiPo) and charging current (typically 1C, which is 3.3A for a 3300mAh battery).
- Start the charging process. Monitor the battery during charging and never leave it unattended.
- Une fois la charge terminée, déconnectez la batterie du chargeur.
Important: Always store LiPo batteries in a fire-safe bag or container. Do not overcharge or over-discharge batteries.
2.2 Préparation de la télécommande
Ensure the remote control has fresh batteries installed. The 10-channel radio control system is pre-bound to the helicopter from the factory. If re-binding is ever required, refer to the specific instructions for the X1 Flight Control System and your remote control model.
2.3 Vérifications avant vol
Avant chaque vol, effectuez les vérifications suivantes :
- Inspection visuelle : Check for any visible damage to the fuselage, rotor blades, landing gear, and tail boom.
- Pales du rotor : Ensure main and tail rotor blades are securely attached and free from cracks or chips.
- Battery Securement: Confirm the flight battery is fully charged and securely installed in the helicopter's battery compartment.
- Surfaces de contrôle : Power on the remote control first, then the helicopter. Verify all control surfaces (cyclic, collective, rudder) respond correctly and smoothly to remote control inputs.
- Moteur et ESC : Listen for any unusual noises during initial power-up.

3. Mode d'emploi
Operating an RC helicopter requires practice and adherence to safety guidelines. Always fly in a safe, open area away from people, animals, and obstacles.
3.1 Consignes de sécurité
- Emplacement: Fly in open spaces, clear of buildings, trees, power lines, and water.
- Météo: Avoid flying in windy conditions, rain, or snow.
- Distance: Maintain a safe distance from yourself and others. The rotating blades can cause serious injury.
- Sécurité des batteries : Never operate with damaged batteries. Disconnect the battery immediately after flight.
- Surveillance: La supervision d'un adulte est recommandée pour les jeunes opérateurs.
- Vérification avant vol : Always perform the checks outlined in Section 2.3.
3.2 Commandes de vol de base
The 10-channel remote control provides precise command over the helicopter's movements. Familiarize yourself with the stick functions before attempting flight.
- Throttle/Collective: Controls the main rotor speed and blade pitch, affecting altitude. (Typically left stick, vertical axis)
- Rudder/Yaw: Controls the tail rotor, rotating the helicopter left or right around its vertical axis. (Typically left stick, horizontal axis)
- Aileron/Roll: Tilts the helicopter left or right, causing it to move sideways. (Typically right stick, horizontal axis)
- Elevator/Pitch: Tilts the helicopter forward or backward, causing it to move forward or backward. (Typically right stick, vertical axis)
Practice gentle movements and hovering at low altitudes before attempting advanced maneuvers.

4. Entretien
Regular maintenance ensures the longevity and safe operation of your RC helicopter.
4.1 Post-Flight Checks
- Déconnecter la batterie : Always disconnect the flight battery immediately after landing.
- Inspecter les dommages : Check for any new cracks, loose screws, or bent parts.
- Propreté: Remove any dirt, grass, or debris from the rotors, motors, and fuselage.
- Température du moteur : Feel the motors and ESC for excessive heat.
4.2 Entretien général
- Stockage: Rangez l'hélicoptère et la télécommande dans un endroit frais et sec, à l'abri de la lumière directe du soleil.
- Stockage de la batterie : Store LiPo batteries at a "storage charge" (approximately 3.8V per cell) if not used for extended periods. Never store fully charged or fully discharged.
- Lubrification: Periodically check moving parts for smooth operation. Apply a small amount of silicone lubricant to linkages if necessary.
- Fixations : Regularly check all screws and bolts for tightness. Vibrations during flight can cause them to loosen.
