In recent years, hobby-grade “ready-to-run” (or “RTR”) models have become available from everybody. RC cars are a fantastic family hobby. First of all, I want to tell you the advantages of Radio Control Car.
Toy class vehicles are easy to operate, have a relatively low danger level (top speeds are typically under 20 mph (32 km/h) (with most capable of only about 10 mph (16 km/h) ), and are even easier to set up than the simplest hobby class ready-to-run vehicles (RTR’s). Toy class vehicles are usually modeled after real cars, and often feature details that hobby class vehicles lack, like working lights, sounds, windows, opening doors and hoods, and realistic interiors at the expense of weight and durability. Some vehicles also feature working sound systems with radios or MP3 player inputs. There is also an almost endless array of toy R/C vehicle designs, ranging from common cars and trucks, to tanks, bulldozers, and motor cycles, to increasingly odd vehicles with unorthodox designs.
Then,I will show you the Principles of operation.Radio-Controled cars use a common set of components for their control and operation. All cars require a transmitter, which has the joysticks for control, or in pistol grip form, a trigger for throttle and a wheel for turning, and a receiver which sits inside the car. The receiver changes the radio signal broadcast from the transmitter into suitable electrical control signals for the other components of the control system. Most radio systems utilize amplitude modulation for the radio signal and encode the control positions with pulse width modulation. Upgraded radio systems are available that use the more robust frequency modulation and pulse code modulation. The radio is wired up to either electronic speed controls or servomechanisms (shortened to “servo” in common usage) which perform actions such as throttle control, braking, steering, and on some cars, engaging either forward or reverse gears. Electronic speed controls and servos are commanded by the receiver through pulse width modulation; pulse duration sets either the amount of current that an electronic speed control allows to flow into the electric motor or sets the angle of the servo. On the models the servo is attached to at least the steering mechanism; rotation of the servo is mechanically changed into a force which steers the wheels on the model, generally through adjustable turnbuckle linkages. Servo savers are integrated into all steering linkages and some nitro throttle linkages. A servo saver is a flexible link between the servo and its linkage that protects the servo’s internal gears from damage during impacts or stress.
Now let’s take a closer look at each of the main components.

The transmitter sends a control signal to the receiver using radio waves, which then drives a motor , causing a specific action to occur. The motor in a car may cause the wheels to turn, while the motor in a plane may adjust the flaps. The power source is typically a rechargeable battery pack, but sometimes it’s just normal batteries.
