A radio-controlled airplane is a toy plane that you can control using a remote control that looks like a walkie-talkie. When you press buttons on the remote, it sends signals to the plane's electronic system, which tells the plane to move in different directions, like up, down, left, and right.
The plane is powered by a battery and has a small motor that propels it forward. There are also small wings on the plane that help it steer and stay in the air.
Flying a radio-controlled airplane can be lots of fun, but it's important to always follow the rules and safety guidelines. You should only fly your plane in designated areas, away from people and buildings, and make sure it's never too close to other people's planes or the ground.
