A radio-controlled car (or RC car) is a self-powered model car or truck that can be controlled from a distance using a dedicated transmitter.The term RC is used to refer to remote control and radio control, where remote control includes vehicles connected to the controller via wires, however, the general use of RC today generally refers to vehicles controlled by RF links.This article focuses only on vehicles controlled by radio.
Cars are powered by various sources.
The electric model is driven by small but powerful electric motors and rechargeable nickel-cadmium, nickel-metal hydrogen or lithium-polymer batteries.There are also brush motors or brushless motors.Most fuel-driven models use glowing plug engines, and small internal combustion engines are driven by a special mixture of methane, methanol and oil (in most cases, a mixture of castor oil and synthetic oil.
These are called nitro cars.
Recently, a very large model powered by a small gasoline engine was introduced, similar to a tandem fine-tuning motor using a mixture of oil and gasoline.Compared to fuel-driven models, electric vehicles are often considered easier for novices to use, but electric vehicles are just as complex with higher budgets and skill levels.In both categories, there are roads and off-road vehicles.
The off-road model is built with a fully functional off-road suspension and a wide range of tire options that can be used on various types of terrain.On road vehicles, the strength of the suspension is much smaller, strictly limited to the smooth pavement.Over the past decade, advances in road vehicles have made today's standards as adjustable as many full-size cars.
Both toy-class and hobby-class models have radio-controlled cars.The term toy or toy grade for radio-controlled cars is used to describe pre-assembled types of vehicles that are usually found in discount stores and consumer stores.Sometimes they are called Radio sheds.Some toy-grade RC models can also be found in hobby stores, trying to get some market share from discount stores and attracting young users.
One of the main advantages of the toy RC vehicle is the cost.Average medium-The price of the toy RC car is around $50.$100 cheaper than an entry-level electric hobby car.
Toy Class vehicles are easy to operate and are relatively low in risk (the top speed is usually below 20 mph (32 km/h) (Most abilities are only 10 mph (16 km/h) and are easier to set up than the simplest hobby class (RTR) ready to run the vehicle.Toy vehicles are usually imitation of real cars and often have details that are lacking in hobby vehicles such as work lights, sounds, windows, open doors and hood, real interiors at the cost of weight and durability.Some vehicles are also equipped with a working sound system with radio or MP3 player input.
The design of toy RC vehicles is also almost endless, from regular cars and trucks to tanks, bulldozers and motorcycles to increasingly strange vehicles designed to be unorthodox.The disadvantage of toy-grade RC cars is usually to focus on design when manufacturing, while reducing production costs.Although hobby class cars have a standardized motor and independent electronic components that can be replaced separately if they fail, toy class cars are usually made with non-standard motors, the vehicle design integrates chassis components and individual electronic circuit boards that cannot be replaced.
This makes it difficult to fix them, except for the Nikko model and some radio shed models, if not impossible.Usually, when a component on a vehicle fails, the entire vehicle must be thrown away.Poor performance.Most are equipped with small weak motors and powered by cheap alkaline or NiCad batteries, meaning that their maximum speed is usually only 5-15 miles per hour, they run very short before they need new batteries.
Most people lack any form of suspension, and the design of the suspension is very primitive or crude.Steering is usually out of proportion (only three positions of straight line, full left and full right), and there is usually no proportional throttle, only stop and full power.The routes of many smaller cars have been closed and they are easily damaged in the crash.
In recent years, every major radio-controlled car manufacturer has been able to buy hobby-class (or RTR) models ready to run, attracting many that would otherwise have purchased pre-assembled cars (ARTR or race rollers) fans.This type of vehicle hardly needs final assembly and in most cases the body is painted and trimmed before use, there is little or no need for the owner's work (except for the purchase and installation of batteries ).At present, many cars and trucks can only be provided in the form of ready-to-run.
The increasing popularity of RTR vehicles has prompted many manufacturers to stop producing kit vehicles.High-spec racing cars are usually still available or only for sale as kits, with Rehu, Losi, HPI and Tamiya sales kits and RTR versions, with the benefits of kit versions being upgrading components or reducing costs, respectively.Hobby RC cars cost $80-$1500
