Daily activity is now very stressful for most of us and that means that relaxation is more important than ever. But, also, a wide variety of leisure activities are available, so that we find it hard to decide which one to choose.

But why choose Modeling ?? - Because Modeling has something to offer everyone: those who want relaxation, those seeking more adrenalin, those who want to do research, those who want to learn the technique of high level of fishing enthusiasts - be they young or age.
For young sports enthusiasts it means a technical application that teaches important principles of functioning of transport (planes, boats, cars) and what are the skills required to achieve funtionale models of such vehicles. Then, develop the spirit of competition and desire to be the best. For adults is a unique means of relaxation, communication with the youth to rediscover the pleasure to build, to participate in competitions - everything involves a complex hobby, and that tends to be maintained in good physical and mental shape.

Modeling has several main branches: model plane, model boats, model cars, model rockets.
Everyone can choose one of these branches, or more, taking into account that each branch has different technical approach, requiring different locations and patterns of evolution, not least, require further expenditure for materials.


How does a R/C system work ?
3 things are participating in these operations:
- Emitter, who send signals when you move the stick to control the model sites, such as speed, direction and altitude of the model plane.
- Receiver, which is installed on the model and is powered by a pack of 4 batteries. It receives signals from the transmitter and convert them into electrical signals which are sent to servos.
- Servos, the final execution elements, are small motors with gear box, connected for example to the rudder or the elevator of the model plane to respond to your command.

On Cars and Boats RC systems can use two channels because they need two functions: engine (forward - back) and rudder (left - right).

For the model plane you need a RC system with four channels required to control the engine, rudder, ailerons and elevator.

What types of engines do models use ?
Most R/C modern models use internal combustion engines or electric motors with special batteries. Choosing the type of engine (electric or thermal) remain at your choice.

Internal combustion engines
In most categories most frequently used are the engines with a two-stroke cylinder that runs on methanol fuel or gasoline. The advantage of engine that runs on methanol fuel is that they are small, lightweight and extremely powerfull. Like the car engine, engine capacity is measured in cubic centimeters, for example a engine for a trainer aeromodel type may have the capacity ranging between 2.5 cc and 20 cc.
Many model cars and model boats use a pull-start mechanism to start.
Model aircraft generally start out with a starter.
Two-stroke engines use glowplugs to start.
As the name suggests, the glowplug ignites the fuel, so the rotation shaft starts to move. To ignite a glowplug you needs electricity from a battery, which is removed once the engine has started.

Motors are most commonly used to model cars and model boats, and increasingly more model plane use electric motors. This trend is fueled by the appearance on the market, with smaller and smaller prices, of brushless motors with powers that sometime exceeding the power of internal combustion engines. The choice is yours.

Batteries and Chargers
The operation of an electric motor requires a speed controller and a power source. The enthusiasts are using the NiMH or LiPo batteries that are available in different shapes and capacities to suit your applications. Common feature of these batteries is that they support large loading currents (ex 25 C).
Of course, if you have batteries you will need a charger. Chargers are divided into two categories: fast, which can charge a battery in about 30 to 60 minutes and slow to do the same in 10-14 hours as they have a much
smaller charging rate.
These chargers work at outlet or source of 12 V. To prevent overloading, which irreversibly affects batteries, modern chargers have the essential property to detect the end of charging, then automatically stop the process. This gives the user the assurance that batteries are properly charged and that can be used at any time even if charging process was made several days ago.


Speed controllers
They are electronic devices with microprocessor power used on models to determine the direction of movement (forward / reverse) and speed.

How can you drive several models at the same time in the same place ?
Any R/C system has its frequency band. The usual bands are 35 MHz and 40 MHz.
To operate several models at the same time, each band is divided into multiple channels. So, for example 35 MHz band, channel 60 has a frequency 35,000 MHz, while channel 61 has frequency 35,010 MHz. As long as each model uses a different channel (a different frequency) there are no problems.

In order to change the channel, transmitter and receiver have one crystal that can be changed in seconds. Each crystal have the channel number and frequency printed on it, and must be the same on the transmitter and on the receiver.

In the last few years we can take benefits from a new and inovative technology - 2.4 GHz Spread Spectrum. Using this RC systems we don't need crystals anymore.

I need more technical skills ?
The idea of enthusiasts is generally associated with the use of devices with a high technical degree.

If you don't have a high level of technical knowledge, this hobby will help you in getting in time such knowledge. Perhaps you will find great pleasure in discovering a different technical principles which you have not given very much importance so far.
For RTR Models (Ready To Run) or RTF (Ready To Fly) level of knowledge required is minimal and they are thought to introduce you to this area with minimum effort.

For Models ARF (Almost Ready to Fly) kits and built, beginners need some technical skills that are generally known by any man. Installation instructions provide sufficient information to assemble the model.
