4. Operating Instructions
Familiarize yourself with the radio controller and tank functions:
- Power On: Turn on the tank's power switch, then turn on the radio controller. The tank and controller should automatically pair.
- Movement: Use the joysticks on the radio controller to control forward, backward, left, and right movement. The tank features pivot steering for realistic maneuvers.
- Turret Control: Use the designated controls on the remote to rotate the turret up to 340 degrees.
- Barrel Control: Use separate controls to move the barrel up and down by approximately 30 degrees.
- BB Pellet Shooting: Press the firing button on the controller to shoot 6mm BB pellets. The tank will exhibit a hull-recoil action and firing sound effect. Ensure no obstacles are within the 20m shooting range and always aim safely.
