Not in a straight line: Adjust the SVC knob of the remote control to 0 Turning off the gyroscope will cause it to travel in a straight line. Recheck if the remote control ST-TRIM (steering adjustment) is at the center point, and use ST-TRIM (steering adjustment) to adjust the car to move in a straight line. 2. Automatic forward/backward movement of the car: Align the TH-TRIM arrow on the remote control with the center point in the power on state, then turn off the remote control and restart it (reminder: When starting up, do not touch the throttle trigger (trigger) with your hands, which will cause the car to move automatically) 3. When the car runs, it becomes unstable and shakes: If the car is unstable, it may deviate due to terrain and speed issues. If the speed is (100%) fast, the car's grip may be insufficient, resulting in deviation 4. Re code: When the remote control and the vehicle are powered on normally, use the matching code to match the BIND pin hole on the vehicle. The front lights of the vehicle change from flashing to permanently on, indicating that the remote control has successfully paired with the vehicle 5. No response to vehicle forward/backward: When the vehicle does not have throttle function, pull the throttle trigger to the full forward direction and adjust TH-D/R to position 10.
