Why Is My RC Car Going Slow?

RC Cars are a great way to have fun and pass the time. They provide hours of entertainment and can be enjoyed by both adults and children alike.

But sometimes RC cars can go slow, or even stop working altogether. This can be a frustrating problem, so it’s important to understand why this might be happening.

Battery Issues

The most common cause of slow or stopped RC car movement is a battery issue. If the car isn’t getting enough power, it won’t be able to move at its normal speed.

To fix this, you’ll need to charge or replace the battery. If you’re using rechargeable batteries, make sure they’re completely charged before use. Additionally, some models may require specific types of batteries for optimal performance.

Faulty Motor

Another possible cause of slow or stopped RC car movement is if the motor is faulty. Faulty motors will not spin as quickly as they should, leading to slower speeds or even complete stoppage. If this is the case, you’ll need to replace the motor with a new one.

Dirty Contacts

Dirty contacts can also lead to slower speeds in your RC car. The contacts between the motor and battery should be clean and free from corrosion in order for them to work properly.

You can clean these contacts with some rubbing alcohol.


There are many reasons why an RC car may go slow or even stop working altogether. Most commonly it could be due to battery issues, faulty motors and dirty contacts between the battery and motor. It’s important to identify what could be causing your RC car to go slow so that you can take steps towards fixing it and getting back out on the track!
