Radio controlled cars, remote controlled cars or RC cars and trucks are devices, with which to have fun. However, some RC hobbyists take their fun very seriously indeed. They want their RC car or truck to be the most realistic or the fastest by tweaking the basic kit and by tuning up the engine. This is not a new phenomenon at all. Hobbyists have been building and racing model cars since the 1940's. However, these early cars were constrained by technology.
In the early days of the hobby, the models had to be manufactured by hand by hobbyists and radio control was ineffective and too dear for home use. Those early models were controlled remotely by wire. Therefore remote controlled model cars could only run the distance of the wire, which meant in effect that the car went round and round the operator. It was not until the 1960's that radio control was available and this meant proper races around a proper race track. The true hobby-cum-sport of model racing was born.

After the hobby or sport had been opened up by real radio control, it became more exciting and it attracted more hobbyists and with them came improvement and commercial interest. This means that the technology involved in radio controlled cars and trucks has come on in leaps and bounds. One aspect worth mentioning here is that a big differentiation between model cars used to be whether they were remote controlled or radio controlled. Unfortunately, they are both shortened to RC and so the terms are often used arbitrarily these days.
The most popular RC cars for beginners are the electrically driven model cars and trucks. Electric RC cars have to rely on rechargeable batteries for power. This is their main disadvantage, but being electrically driven also means that the car is cleaner and more responsive to control. Electrically driven cars are apt to be lighter and therefore faster. They are cleaner because there is no exhaust. They are easier to maintain, but also less easy to modify. They accelerate extremely quickly
The next step for many RC hobbyists is the Nitro car. Nitro cars are driven by miniature engines which run on a mixture of nitromethane and lubricating oil. These cars are very fast with a fast acceleration. They can reach and maintain higher speeds than electric cars, whose batteries are constantly running down which means less power for speed.
Nitro cars and trucks are noisy and smelly. They make the loud whine that people associate with model racing, but they also produce exhaust which means that they cannot be used indoors.
More and more replica cars are now using petroleum powered RC cars. These replicas tend to be the bigger ones. These RC cars and trucks have engines that are more familiar to the non-specialist, but they have all the characteristics of an typical car. They produce fumes, noise and are slower to accelerate that the other kinds. However, petrol driven engines will last longer than nitro engines. Because these models are larger, they can take more fuel on board and so go longer distances.
All three of the above types can then be on-road or off-road. On-road cars will be built for racing only and the tyres will be racing tyres and the engines will be finely tuned to reach top speed quickly and maintain it for the duration of the race. On the other hand, off-road RC cars are built for travelling up and down hill over all kinds of natural objects, so the engine has to have more torque and the tyres have to be able to maintain a good grip. These cars are usually slower.
The last distinguishing attribute of the different RC cars is size or more precisely the scale. 1:8 was and still is quite popular. That scale means that for every eight inches of the real car, the model is one inch long. Other popular sizes are 1:10 and 1:12, but there is a new breed of RC cars and trucks gaining popularity, the monster 1:5 cars and trucks, which are petrol powered.
