When you are looking at radio control helicopters, you will quickly find that they are not a generalized item. Instead, these items come in a variety of styles and sizes and can even range in the type of energy that is used to assist them in flying. What you will want to consider is that each of these items can have their own unique use to you.
Perhaps the best choice you have is the electric models. You will find that these are the ones that most people will use because they are user friendly and they will give you the chance to learn the basics of RC toys. Using a simple set of internal mechanisms, you will operate them with your remote and they tend to be very responsive. For a power source, these items will typically have a rechargeable battery that you will be able to remove from them.
Inside of the remote and the radio control helicopters, you will find two different transmitters. These transmitters will give you the chance to adjust the way that your helicopter flies and can be either a simple internal system or a more complex one on larger, more expensive units. Many RC toys have a variety of options attached to them.
These radio control helicopters will come with some different axel options on them. For example, you can have a coaxial helicopter as it will have a single rotor that has been placed on the central axis. In some cases, there may be a secondary rotor on the tail, although it typically isn't needed.
RC toys that use a fixed pitch radio control in turn don't have a collective servo. This means that you cannot adjust their rotor. But since they operate on fewer channels, many beginners will find that they work out well. Just note that those who are looking to have shows with their helicopters won't be able to do many of the acrobatics that some of the more advanced models will allow them.
While you are looking over your options, you will also notice that there is a variety of choices you have, just keep in mind that these units will use a variety of controls. You may have a remote control that uses transmitters to increase speed and height while a simple unit may do nothing more than help you steer your helicopter from left to right.
That will be important to keep in mind, because there are so many different choices that radio control helicopters will provide you. Before you continue through the process, sit down and consider what you want to be able to do with your RC toys. From that point, you will be able to not only locate the perfect choice for your needs, but you will also be able to make the most of your experience as well. Just be sure that you pay close attention to quality and durability when you select any unit as this can vary as much as the price of the unit can.
