Tell me about my fourth grade composition of toy racing in 500 words.

Although there are many toys at home, I only like one kind of toy, that is, remote control racing. Let me introduce my remote-controlled racing car to you.

My remote control racing car is divided into two parts, one is the racing car and the other is the remote control. First of all, allow me to introduce racing cars to you.

My remote control racing car looks exactly like the F 1 racing car on TV. The car is 32 cm long, 0/5 cm wide and 6 cm high. The back of the driver's seat and the front of the car are gray, and the rest are black. There are many two numbers on both sides of the car, which is twenty-three. There is a man sitting in the driver's seat, and that man is the driver. The driver wears a helmet and the driver is neatly dressed. Behind the driver, there is a long and straight antenna. Whenever the car is driving, the antenna will swing, just like a beautiful dog swinging its beautiful tail. The antenna is used for receiving control. The wheels of remote-controlled racing cars are different from those of F 1 racing cars. F 1 The wheels of the racing car are solid and a lot of materials are used, which slows down the speed of the racing car. The wheels of the remote control racing car are hollow, which not only saves materials but also improves the speed of the remote control racing car. The head of the racing car has a bumper with iron inside and rubber outside. Bumpers reduce the impact of racing cars. Make the car durable.

Everyone must have played a little remote control racing! Its motor is very small and its running speed is very slow, while my remote control racing motor is very big, which is twice as fast as that of the small motor. In this way, the remote control racing car plays the role of acceleration and recoil.

The battery is at the bottom. A * * * needs four rechargeable batteries. On the left side of the bottom, there is a red button. There are five or six English letters written next to the button, two English letters written above and three English letters written below. Opening means opening, and closing means reversing. When you want to play, you push the button to the top and the car will start. You are using the remote control. Racing is not an ordinary "small soldier". Racing is a serious and obedient little soldier. At your command. If you don't play, just press the button to the end, and the remote racing will be turned off, which won't waste the battery. There are two silvery white bells behind the battery, which are whiter than silver, and play a role in reducing the volume of the remote control racing car and protecting the remote control racing car. There are two wheels beside the spring. It must be strange for everyone to hear this wheel. This kind of wheel is different from the wheels of big trucks and taxis you see, and its function is different. Big trucks have big wheels, which are used for running, but these wheels are different. This kind of wheel is one or two times smaller than that of a big truck to prevent other cars from attacking you. This kind of car is not easy to lose. For example, if someone else is exactly like your remote control racing car, you can't make a mistake, because there are several words written in the middle of the spring. You just need to remember them. These numbers are: ON845.

The remote control of the racing car is different. The remote control and the mobile phone look exactly the same, and they have different batteries. Ordinary batteries are round, but this kind of battery is big, flat and square. There are two buttons above the battery. If you want to get on the bus, you can get on it. If you push it down, the car will go back. How's it going? Listen! The conductor has a steering wheel in front and a steering wheel in back. If you turn right, it will turn right. Anyway, how you command it, it moves. If you go forward, you can press the forward button, just like protecting you. There is also an antenna at the top to control the car. An antenna transmits information just like an ant's antenna.

Everyone likes this cool and fun remote control racing car. Buy one if you like, and have fun!
