Radio controlled(RC) models have been a deep interest of enthusiastic hobbyists for over half a century. However, initial slow progress of technology in this field had differed a potential fast take-off of the industry, until 1970 s.
The slower pace of development of RC models of car as a children s toy, and more interestingly as the companion for the serious hobbyist, took a great leap forward smashing some barriers, with the invention of the more convenient , power-efficient and lightweight semiconductor transistor in place of the old electron tube. Nevertheless, electronics solved just one of the challenges before the industry, which required emergence of a wireless platform that could convey precise control signals to the moving model. A suitable engine to drive the model was also a primary requirement. By then, the internal combustion engines had been in existence for several decades. Yet, a scaled down version of the same was still a challenge. The demand for characteristic differences of the model included, fast acceleration, enormously high speed, stability while running, ruggedness and cost. The development of the Nitro methane fuelled light engine, (more commonly called the Nitro engine) fulfilled the demand.
Meanwhile, technology kept on moving forward, in search of some alternative electrical substitute for the IC engine, usable in models. The main challenge before this endeavour was, finding, -rather developing- a battery that can provide a high impulsive power when needed, store adequate energy for a reasonable run, safety in the face of possible impact damage, light weight, rechargeability etc. This demand was reasonably met with the development of the Lithium Polymer battery. The brushless high torque motor came in place of the Nitro engine.
The Nitro engine is capable of generating instantaneous torque required to accelerate the car to speeds of above 100 mph in a second! They can be refueled in a short time.
The electrical counterpart still lags behind in possible maximum acceleration and speed, but is convenient and easier to operate and maintain.
The control facility provided by newer servo systems, digital encoders/decoders, extremely stable RF signals and improved modulations techniques embedded into modern radio-control systems definitely out performs the all-analogue old versions. In short, modern systems offer easy and accurate controllability to the operator.The Nitro engine is capable of generating instantaneous torque required to accelerate the car to speeds of above 100 mph in a second!
