5. Setup

5.1 Battery Charging

1. Connect the provided charger to a suitable power source.
2. Connect the helicopter's battery (11.1V 750mAh LiPo) to the charger.
3. Ensure the battery is charged fully before the first flight. Refer to the charger's instructions for specific charging indicators and times.
4. Always supervise battery charging and disconnect once fully charged to prevent overcharging.

5.2 Transmitter Preparation

• Install the necessary batteries into the transmitter (refer to transmitter manual for battery type and installation).
• Familiarize yourself with the transmitter's controls (throttle, cyclic, collective, rudder). This RTF version is set for Right-Hand Control (Mode 2).

5.3 Binding the Helicopter and Transmitter

Your RTF package should come pre-bound. If re-binding is necessary, follow these general steps:

1. Ensure both the helicopter and transmitter are powered off.
2. Place the helicopter on a flat, stable surface.
3. Turn on the transmitter while holding the bind button (if applicable).
4. Power on the helicopter. The indicator lights on the helicopter and transmitter should show a successful bind (refer to specific binding instructions in the included quick start guide or transmitter manual).

5.4 Pre-Flight Checks

• Inspect the helicopter for any visible damage, loose screws, or bent parts.
• Ensure all rotor blades are securely attached and free to move.
• Verify the battery is fully charged and securely installed.
• Check that all control surfaces respond correctly to transmitter inputs (e.g., cyclic moves swashplate, collective changes blade pitch, rudder controls tail rotor).
• Perform a range check of the radio system in an open area.

6. Operating Instructions

6.1 Flight Environment

• Fly in open, clear areas away from people, animals, buildings, and power lines.
• Avoid flying in windy conditions, especially for initial flights.
• Maintain a clear line of sight to the helicopter at all times.

6.2 Basic Flight Controls (Mode 2 - Right-Hand Control)

• Left Stick (Throttle/Rudder):
  • Up/Down: Controls collective pitch/throttle for altitude.
  • Left/Right: Controls rudder for yaw (nose direction).
• Right Stick (Aileron/Elevator):
  • Up/Down: Controls elevator for pitch (forward/backward movement).
  • Left/Right: Controls aileron for roll (left/right movement).

6.3 Takeoff and Landing

1. Takeoff: Place the helicopter on a flat surface. Slowly increase throttle until the helicopter lifts off smoothly. Make small, precise adjustments to maintain stability.
2. Landing: Gently reduce throttle while maintaining control. Aim for a soft, controlled descent. Once on the ground, fully reduce throttle to stop the rotors.

6.4 3D Stunt Flying

The GOOSKY Legend S2 MAX is capable of advanced 3D stunts and inverted flight. This requires significant practice and skill. It is highly recommended to practice on a flight simulator before attempting complex maneuvers with the actual helicopter. Ensure you are in a large, clear area when practicing 3D flight.

The GTS control system and ELRS telemetry provide precise control for these advanced maneuvers. Utilize the optional Bluetooth tuning via the app to customize flight performance to your preference and skill level.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your GOOSKY Legend S2 MAX helicopter.

• After Each Flight:
  • Inspect for any visible damage, cracks, or loose connections.
  • Check rotor blades for nicks or damage. Replace if necessary.
  • Ensure all screws are tight, especially on critical components like the main rotor head and tail assembly.
  • Allow the battery to cool before recharging.
• Periodic Maintenance:
  • Clean the helicopter with a soft, dry cloth. Avoid water or solvents.
  • Check for smooth movement of all linkages and servos. Lubricate moving parts with appropriate RC-grade lubricant if needed.
  • Inspect wiring for fraying or damage.
  • Verify the integrity of the carbon-plastic composite frame.
• Battery Care:
  • Store LiPo batteries in a cool, dry place, ideally in a fire-safe bag.
  • Do not overcharge or over-discharge batteries.
  • If a battery is puffed or damaged, dispose of it safely according to local regulations.
