RC cars are radio-controlled vehicles that are operated by a remote control transmitter. These cars can range in size from tiny micro RC cars that fit in the palm of your hand to larger models that can reach speeds of over 100mph.

Some common types of RC cars include:

1. On-road cars – These are designed for racing on smooth surfaces such as paved roads or indoor tracks. They have low ground clearance and are often built for speed and maneuverability.
2. Off-road cars – These are designed for racing or bashing on rough terrain such as dirt, gravel, or grass. They have high ground clearance and are often built with larger wheels and stronger suspension systems.
3. Drift cars – These are designed for performing controlled slides or drifts around corners. They have slick tires and are often rear-wheel drive, allowing them to break traction and slide sideways.
4. Monster trucks – These are larger, more rugged vehicles designed for off-road racing or freestyle stunts. They have oversized tires, high ground clearance, and powerful motors.
5. Rock crawlers – These are designed for navigating over rough, rocky terrain. They have large, grippy tires and low gearing for maximum torque.

RC cars can be modified and customized with a variety of accessories such as upgraded motors, batteries, and suspension systems, as well as body shells and decals. They can provide hours of entertainment and are popular with hobbyists of all ages.
