The Remote control helicopter or radio control helicopter is said to be the fastest growing hobby in the radio control world. The first of the practical rc helicopter started off sometime in the 70s or 80s. After several waves of development they become more improved and refined to what we know as the remote control gas helicopter or gas rc helicopter for short. These gas powered rc helicopter were the only widely available types of rc helicopter then.
It took a lot of time, money and effort to put together a remote control gas helicopter before even one could fly it. Once assembled, it also took even more courage and effort to learn and get used to the controls and perform additional & needed adjustments just to get the flight control tested. Only then is the pilot confident enough to take the radio controlled helicopter to flight.
A novice or beginner would had to go through even more hurdles as compared to the ones with more experience. If the novice had to test the rc helicopter to flight while he or she was even not used to the controls, the risk of crashing and damaging the helicopter was even greater and thus putting all the effort, time and money in greater expense and making the experience a really expensive one. This is one of the reasons why there were not so many people in the remote control helicopter hobby.
As more rapid development in technology evolves, more advanced technologies previously only available to most aviation & aerospace industries were then more accessible with feasable and applicable applications in the general consumer technology, thus including the radio control world, particularly the remote control helicopter.
This made huge impact and various improvements to make it more easier for people getting into the rc helicopter hobby. New electric motor engines powered by batteries were eventually introduced and thus making it even more easier for people to get into flying rc helicopters.
With this continuing trend, the electric rc helicopter now become widely available as well. Even these are now growing to many more types and models with even smaller in size like the mini rc helicopter, micro rc helicopter and currently the so called pico rc helicopter. As the types develop even further, it also gets a wider range of users for the remote control helicopter.
