Choosing the best Radio control helicopters
Radio control helicopters are some of the most celebrated forms of entertainment by people of all age groups. In buying these helicopters you should consider certain factors.
The cost of acquiring any of these helicopters depends largely on the amount of human effort and skills involved in coming up with it. Where appropriate technology has been used the Radio control helicopters are to a high degree similar to the real helicopters both in appearance and performance.
A very important point to bear in mind is that the performance or quality of the Radio controlhelicopters depends on the quality of vital parts like the blades and rotors. Smooth blades conforming to standard design requirements are efficient since they possess good aeronautical characteristics.ie less friction with air and thus result to more efficient movement. This means that the blades are more responsive to your control as opposed to poorly designed blades.
The intended use of the Radio control helicopters is another major factor to be taken into consideration before buying one. There are those mainly for stunts as well as those predominantly used for flight. The ones for stunts happen to be cheaper hence making them attractive to many potential buyers.Other types of helicopters like the scale helicopters are more susceptible to crushing and therefore should be chosen only where the flight conditions are good and users are experts.
The materials used for the manufacture of the Radio control helicopters are as diverse as the end products and therefore forms yet another reference point for decision making by potential buyers. Mostly light materials are used in making many of the body parts of the helicopters. Dominant of these materials is fiberglass due to its light weight a characteristic suitable for all aircrafts. Hydrocarbon polymers and synthetic fibers are as well greatly utilized due to their non-reactive nature which discourages corrosion and consequent wearing out of the helicopter body parts. Examples of the polymers are the polystyrene, polycarbonate and many others.
Most aircrafts use the principle of jet propulsion where a jet of ejected gas in the opposite direction imparts a reaction onto the helicopter causing movement in the direction of flight. However this article will not go into the detailed science of aerodynamics of the Radio control helicopters. Power which drives most of these helicopters is derived from burning of fuels in the engines which inturn produce the above mentioned gas jets. Mostly used fuels include nitrogen and monoxides of nitrogen gas. Therefore the type of fuel used has to be considered while choosing the helicopter to buy.
