So imagine a little car that you can control with a remote that you hold in your hand. This car is called a radio-controlled off-road buggy because it is really good at driving on bumpy or rocky ground.
The car is called "1:10" because it is built to be 1/10th the size of a real off-road buggy. This helps it fit in your hand, but still be big enough to move around outside.
The remote control that you hold in your hand sends signals to the car through the air, just like talking to your friends through the telephone. When you push the buttons on the remote, the car gets the signal and knows what you want it to do.
The off-road buggy has special tires that are made to grip onto the ground when it's bumpy or rocky. This helps the car stay on the path you want it to go on.
In summary, a radio-controlled off-road buggy is a little car that you can control with a remote. It is really good at driving on bumpy or rocky ground and has special tires to help it grip onto the ground. It is called "1:10" because it is built to be 1/10th the size of a real off-road buggy.
