2. Turn on the transmitter.
3. Connect the flight battery to the helicopter. Place the helicopter on a flat, level surface.
4. The helicopter's indicator light will flash. Move the throttle stick (left stick) on the transmitter to its lowest position, then to its highest position, and then back to its lowest position.
5. The helicopter's indicator light should become solid, indicating a successful bind. If not, repeat the process.

Panic Mode

In case of loss of control or disorientation, activate the panic mode (refer to transmitter diagram for button location). This feature is designed to help stabilize the helicopter and prevent crashes by automatically leveling the aircraft.

• Battery Care:
  • Do not overcharge or over-discharge the LiPo battery.
  • Store batteries in a cool, dry place away from direct sunlight and extreme temperatures.
  • If the helicopter will not be used for an extended period, store the battery at a partial charge (around 3.8V per cell).
• Storage: Store the helicopter and transmitter in a safe place, away from dust and moisture, when not in use.
