Micro Helicopter Control Systems - Which Type Will You Choose?

Micro Helicopter Control Systems - Which Type Will You Choose?

Micro helicopters generally come equipped with one of two types of remote control systems. If you're in the market for a new micro helicopter, it's important to understand the differences between these types in order to get the most out your purchase. In this article I'll explain the difference between the two control system types and the pros and cons of each. Plus, I'll provide some Bonus tips on some handy features to look for in a control system. Hopefully after reading this you will have a better idea of what to look for in a micro helicopter control system.

The first control system type is Infrared. Infrared control systems use infrared LEDs (similar to those on a TV Remote control) to transmit the signal to one or more infrared receivers on the helicopter itself. These systems are very common with inexpensive micro helicopters because they are very cheap for the manufacturers to incorporate. It might not sound like this type of system would not work very well on an RC helicopter. However, it turns out that in the right setting, infrared LEDs work very well. But that is the key... in the right setting.

Infrared control systems struggle outside in natural daylight; the wavelength of the sun's rays can interfere with the controller. Direct "line of sight" between the helicopter and controller is required. It won't operate through walls, people etc. Basically the helicopter has to "see" the controller. Finally infrared control systems have limited The spectrum. Over 30 to 50 meters from the controller, they tend to lose the signal. Fortunately for us, these requirements are perfectly suited for micro-helicopters. Micro helicopters are operated in enclosed areas in the sun happens to near-infrared technology is very suitable.

The second type of control is the most typical radio frequency or type "RF" control. This can work in a number of different frequency bands, and not suffer the same limitationsIn infrared. Naturally, however, are more expensive to implement RF control and have their own set of potential disadvantages. In general you will not find the controller very cheap RF micro-helicopters.

RF Controls offer a range much longer than infrared counterparts. You do not have the line of sight issues, and indeed are able to pass through walls. In these days when used at home, is full of RF interference technology from our homes. Thingssuch as microwave ovens, cordless phones, computers, wireless routers and cell phones all the potential sources of RF interference. In practice I have found no defects are a major problem for the micro-helicopters. However, there is something to be observed and respected, especially if you have a lot of these types of devices in your home.

There are a number of features that you can search for a micro-helicopter

Before trim - to cut, you cancompensate for minor problems with your helicopter. For example, a bent tail rotor may cause your helicopter to spin in circles. The Trim Adjustment will allow you counteract the problem so it hovers without spinning.

2. Tri-Band or frequency selector switches -- Micro helicopters often come in different "bands" or "Frequencies" that allow multiple helicopters to be flown at the same time without interfering with one another. Some controllers include switches to select between bands/frequencies. This is a very useful feature that allows you to interchange the controller with different helicopters.

3. Ergonomic design -- This may sound like an obvious feature to look for, but when shopping online, a well laid out controller design is often overlooked. Some manufacturers like to design their controllers for looks rather than usability. Make sure that the controls are laid out in a symmetrical fashion that offers easy access to all controls. Trust me; this will make flying much easier.

4. Built in Charging Systems -- This will only be an option for the very low power helicopters, but it's nice not worrying about lugging around a battery charger and staying near electrical outlets when you want to take your helicopter on the go.

In most cases an infrared control system will be more than adequate for controlling a micro helicopter. However, it's important to understand the limitations before making a purchase decision. If you are looking at higher end micro helicopters, an RF controller (my preference) is a worthwhile option to consider. You don't need to worry about line of sight obstacles such as furniture, walls or passersby. The important thing is to understand your options, and make a decision that will provide the most value to you.
