Setup
- Install Controller Batteries: Open the battery compartment on the remote controller and insert 4 AAA batteries (not included), ensuring correct polarity. Close the compartment.
- Charge Car Battery:
- Connect the car's 3.7V 180mAh battery to the provided 5V 2A USB charging cable.
- Connect the USB cable to a compatible USB power source (e.g., computer, USB wall adapter).
- The charging indicator light on the USB cable will show the charging status (e.g., red for charging, off when fully charged).
- Charging takes approximately 30 minutes. Do not overcharge.
- Install Car Battery: Once fully charged, carefully install the 3.7V 180mAh battery into the car's battery compartment. Ensure it is securely connected.
- Power On: Turn on the RC car using its power switch. Then, turn on the remote controller.
- Pairing: The remote controller and car should automatically pair. The red LED on the controller will flash until paired, then remain solid. If pairing fails, turn both off and on again.
Operating Instructions
Familiarize yourself with the remote controller functions before operating the car.
Figure 3: Remote Controller Functions.
- Basic Controls:
- Forward: Push the throttle trigger forward.
- Braking: Push the throttle trigger backward from neutral.
- Step Back (Reverse): Push the throttle trigger backward again from braking position.
- Turn Left/Right: Rotate the steering wheel on the remote controller left or right.
- Advanced Features:
- Drift Function: The car is equipped with specialized drift tires and a 4WD system. To initiate a drift, turn sharply while accelerating. Practice is key to mastering controlled drifts.
- LED Lighting: The car features cool LED headlights and underglow. These lights enhance visibility and appearance, especially when operating in low-light conditions.
- ESP Gyroscope Assisted: This feature helps maintain control. When the vehicle turns out of control, the gyroscope intervenes with the servo to correct slipping wheels, performing independent braking and steering correction until balance is restored.
- Speed Gear Switching: The remote controller may have a speed gear switch to adjust the car's speed.
- Steering Fine-Tuning: Use the steering fine-tuning knob/button on the remote to adjust the steering trim if the car pulls to one side when driving straight.
- Lighting Switch: Use the dedicated switch on the remote to turn the LED lights on or off.
