Remote control helicopters are the tinier versions or editions of helicopters that are controlled remotely from computer or hand held controls. They are like a simulation of the normal helicopter since they are made such that they are like the real helicopters in design and shape, maneuvers, acrobatics and aerodynamics. There are various uses of the helicopters including as toys, for leisure, or for sporting events like air racing. On the other hand, these can be used for other productive activities such as photography and surveillance ethical spying.
The Remote Control helicopters were not in existence before the early 90’s which was when the then electric powered Kalt whisper concept was launched. It was due to technological limitations that a more modern toy helicopter could not be developed. At the time only NiCad batteries were in use. However such batteries were not able to give the high currents required to perform complicated acrobatics and sustain a time of flight that is economical for production.
The advent of the helicopters was celebrated but there was no doubt that more effort needed to be put to realize the full benefits. Luckily, technology evolved really quick and with time more complex Remote Control helicopters were in production. The Battery industry favored the quick growth of the helicopter production. A new type battery replaced earlier batteries. The lead ion provide more current and stored more energy than the previously used ones. They were lighter as compared to the earlier ones making them more favored.
Today’s helicopter engines have diverse power sources. They do not rely on electric currents from batteries.
But also use other power sources like nitro methane or popularly known as nitrous. Although this power source is banned in most nations. Their use is because they can handle bigger engines for a reduced time of flight.
Many Remote Control helicopters’ engines use internal combustion. However such engines are complex and apparently larger than the electric powered engines. Internal combustion engines are flexible in that they can use diverse fossils fuels, such as gasoline, petrol or lpg gas. Some also use biological fuels, that can include the the likes of the hydrogen cell. This is more environment-friendly than the fossil fuels one. However, the biggest drawback with the internal combustion powered helicopter engine is that it is quite expensive and consumes a bigger space. The electric powered engines are the most common helicopter engines that we have today.
Power output of the engine will most likely vary depending on the overall size of the engine if all other factors are held constant. For maximum carry capacity the engine must be light and powerful enough for take off. This way, the helicopter will be able to reach the intended flight displacement and carrying capacity. The source of power source plays the biggest role in determining total engine weight and size of the toy helicopter. Combustion engines can get quite big at times and need a bigger plane while the electric one is the best for smaller remote control helicopters.
