Do you wanna play Toy-grade R/C cars?

Toy-grade R/C cars are typically manufactured with a focus on design coupled with reducing production costs. Whereas a hobby-grade car has separate electronic components that are individually replaceable if they fail, toy grade cars are typically made with components harder to find as spare parts and a single electronic circuit board integrated into the design of the vehicle. Although hobby-grade enthusiasts look down on toy-grade RC cars, their maintenance is much easier than of the hobby-grade models since number of components is drastically smaller, and parts can be harvested at almost no cost from any R/C toy car of the similar size. Performance is proportional to the price, but with addition of hobby-grade type of batteries (LiPo) toy R/C cars can get up to 1/2 the speed of comparable hobby-grade car for 1/5 of the price. Stock toy-grade cars are equipped with weaker motors and are powered by alkaline or NiCad batteries which means their top speed is usually only 5-15 mph. Cheaper ones lack any form of a suspension and the ones that do feature a suspension have very primitive or rudimentary designs. Steering is typically not proportional (with only three positions: straight, full left, and full right) and there is typically no proportional "throttle" either, with stopped and full power usually being the only options. With all the disadvantages, toy-grade R/C cars are a great intro to the hobby, especially for ages 5 – 10, and are cheap platform for modifications and tuning even for older enthusiasts.

Radio-controlled 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. Recently however, 2.4 GHz frequency radios have become the standard for hobby-grade R/C cars.

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 these 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.
After reading what I have written above,I think you should have a try,trust me ,it is amazing!
