Does the servo make a humming sound, or is it completely silent? A silent servo might indicate a problem. Inspect the servo horn and linkages. Make sure they are securely connected and haven't come loose or broken. These small parts are essential for transmitting the servo's movement to the wheels. If the wheels are rubbing on anything, this could be causing problems. Make sure the wheels are free to move and that nothing is obstructing them. Next, check the remote control. Sometimes, the steering problem isn't in the car, but in the remote. Make sure the steering trim is centered. This adjustment helps to fine-tune the steering. If the car pulls to one side, you can adjust the trim to correct it. If the problem persists, it may be time to replace the servo or seek professional help.

Speed and Motor Issues

So, your iMini RC car isn’t as fast as it used to be? Or, maybe it doesn't move at all! Here's how to diagnose speed and motor problems. First, examine the motor. The motor is the heart of your RC car's performance. Check for any debris or obstructions that might be interfering with its operation. Remove any dirt or debris that you find. Listen for unusual noises. If the motor is making grinding or squealing sounds, there might be a problem. This could indicate worn-out brushes or other internal issues. Next, inspect the gears. The gears transmit power from the motor to the wheels. Make sure the gears are clean, well-lubricated, and not stripped or damaged. If the gears are stripped, you'll need to replace them. It's also worth checking the speed controller. The speed controller regulates the power to the motor. If it's malfunctioning, it can affect the car's speed. Look for any signs of damage or overheating. If the problem is persistent, you might need to test the motor directly to see if it's faulty. If the motor is dead, replacement might be the only option.
