History Of Rc Trucks And Principal Of Operation

Share:    

Nitro powered rc trucks are known to have entered the market in the 1940s and had the ability for accurate control

. Then several commercial viable rc vehicles were made available by mid-1960 and were produced by the Italian company called Elettronica Giocattoli (El-Gi). The first model produced by this company was a 1:12 Ferrari 250Lm and was available in the United Kingdom on December of 1996 which was followed by the model 1:10 Ferrari P4. It was in the mid 60s that a British company called Mardave began the production of commercially viable rc vehicles. Their first models were nitro powered vehicles and were sold locally in the early 70s.

This same time, several other commercial products came into production by small firms in the United States. The firms started out as slot vehicle companies before moving into the field of rc vehicles including rc trucks. Some these firms included Thorp, Associated Electric, Scorpion, Delta, Taurus and Dynamic. The early production was of kits scale 1/8 nitro powered aluminums pan vehicles possessing a 0.21 inch engine. Their bodies were made of polycarbonate. The poplar engine at that time was the K&B Veco McCoy. At the time, the primary sanctioning body for a race was the Remotely Operated Auto Racers (ROAR). In the year 1973 to 1974, a company from state of Washington called Jerobee created a 1/12 nitro vehicle by use of a Cox 0.049 inch engine. This is when several other companies createdparts of the car such as heat sinks, Lexan bodies, and larger fuel tanks. The Associated Electric then created the RC12E for a 1/12 scale electric racing.

In the late 1970s, the sole racing category was the 1/8 scale before interests in the 1/12 scale electric racing began to grow. The 1/12 cars were became much liked because of their practical nature that they could be raced throughout winter as an alternative to the impractical 1/8 scale IC car. It was in the year 1976 that a Japanese firm called Tamiya released a series of highly detailed and elegant but mechanically simple on-road electric rc trucks being marketed as meant for radio control. It was an expensive model but they sold rapidly. It was Tamiya firm of Japan that was the first to release off-road rc trucks with real suspension systems after producing remote controlled vehicles that were more purpose built. This advancement towards off road class of vehicles brought about the popularity of rc hobby vehicles.

Principal of operation

The radio controlled trucks or vehicles use a set of components in their control and operation. These rc vehicles need a transmitter with joysticks for control, a wheel for turning, a receiver located inside the car, and a trigger for throttle. They purpose of the receiver is to change the radio signal broadcast from the transmitter the correct electrical control signal that other components of the rc vehicle can understand and be commanded. Many of the radio systems use amplitude modulation for the radio signal while encoding control positions with pulse width modulation.
