The interesting mode of technology in this era of time is radio control helicopter. They are equally popular among teenagers and are getting more famous day by day. The principal on which these helicopters work is the transmission of radio waves and the reception of these ways. The main two parts of these helicopters are described below: - Transmitter (which is placed in the controlling device)
- Receiver (which is placed in the RC helicopter)
When we give some instruction to the helicopter through remote it generates radio waves of specific frequency which are received by the receiver which is placed in the helicopter and it identifies the instruction. These RC helicopters are becoming more and more famous every day. There are many reasons for this popularity; one is the low price of this radio control helicopter, so that everyone can buy them and enjoy them. They are very cheap as compared to the other toys and also different companies launch some special discount prices on particular events as well so that anyone can enjoy them who want them even if someone has low budget. Another factor which makes these helicopters very popular is their durability factor. These helicopters are made up of fine plastic material in the form of small parts and cannot be damaged easily even they fall from great height they can sustain. On the basis of source of power radio control helicopter can be classified as electric batteries models, gasoline engines and nitro methane engines. The helicopters which uses electric batteries as a power source are the ones which are power efficient and are less expensive and if someone wants to wants to have more fun than such a battery must be used which has longer life. The other type is gasoline engine models, these models uses a mixture of gasoline with some organic oil they are more efficient than the electric models. The best type of these helicopters is that which uses nitro methane, methanol and organic oil mixture as the power source, this type of helicopters are highly efficient in their workings and can attain larger altitude and greater speed but these are much expensive than the others, so they are less common then the others. The latest type of these helicopters is the gas RC helicopter, this helicopter is much efficient and is designed for the expert fliers because this type uses some mixture of gas as their power source and provides some extra controls for the user. These type of helicopters i.e. gas radio control helicopter resemble the real helicopters.
