If you have developed a hobby of playing with RC toys, buying the best RC transmitter is important. It is, in fact, the best investment you can make to make your hobby more interesting.
These toys are controlled by small portable devices that send a frequency signal to the receiver of the toy.
5 Best RC Transmitter 2020 Comparison Table
In this article, we will discuss the basics of a transmitter (RC Controller) and what to look for when buying one: price, number of channels, modes, frequency, and other features.
A radio transmitter (TX) and receiver (RX) should be one of the first items to buy when building a quad-top. It can be confusing for RC beginners on how to choose a suitable RC transmitter. Unlike other parts that are often broken or outdated, a good TX can continue for many years, so it’s okay to invest a little more in a decent.
What is an RC transmitter and receiver?
An RC transmitter (also known as radio transmitter or TX) is a device that allows pilots to control the aircraft wirelessly. The signals / commands are received by a radio receiver (RX), which is connected to a flight controller.

The number of channels determines how many individual actions on the plane can be controlled.
For example, the throttle, yaw (turn right and left), pitch (tilt forward and back), and roll (turn left and right), each occupy 1 channel. And for you to see, four channels are the minimum to control a quadcopter (pitch, roll, throttle, yaw).
How To Choose Radio Transmitter & Receiver For Rc Helicopter or Quadcopter
The most popular RC frequency is 2.4GHz. The lower frequencies are available for a longer range such as 27MHz, 72MHz, 433MHz, 900MHz, and 1.3GHz, but are rarely used in Mini Quad.
Just in case you are interested, here are some brief and interesting technical background.
For those of you who have been around the RC scene enough, we will recall 27MHz and 72MHz with the frequency / crystal channels (the crystals were tuned to specific frequency channels to transmit the signal to the receiver that had its own channel crystal essentially Binding together). This technology has existed for decades, which allow for greater range and better signal penetration. However you could interfere with others using the same frequency (even different brands).
Another problem was the large size of the antennas, as they could reach a few feet in length. The crystals used for the selection of channels were also inconvenient because they were easily broken and could change constantly and annoying when flying / driving with others.
The 2.4GHz system is a newer technology and is currently the most popular frequency for small land and air RC vehicles. It becomes the RC standard after introducing new protocols that have introduced a frequency hopping technology that has allowed the user not to pick up frequencies or channels from other pilots. The antenna is smaller and lighter to carry, but usually with a range shorter than 27 / 72Mhz.
You may also have heard of others using 1.3ghz, 900mhz or 433MHz equipment, these are more commonly used for long range or in larger gears.
All transmitter manufacturers switched to new channel jump protocols that made RC very easy to maintain and use. The running software is constantly exploring the best frequency of use and if it detects any interference, it automatically switches to another available channel.
It is doing this many times per second so you never experience radio failures or interference which was a big problem in the RC industry for many years. Another good thing about channel jumping is that you can fly with many other people at the same time without interference.
A transmitter usually comes with a receiver. It is important to know that a TX only works with the radio receiver (also known as RX) from the same manufacturer in general. For example, if you get the Frsky Taranis, you will need to use Frsky RX, or another compatible with Frsky RX.
Linking the transmitter to the receiver is very simple, and is only required the first time a new receiver is being configured with the transmitter. TX will allow you to link multiple receivers to the TX. You can even create separate model profiles for each aircraft so you can have different configurations for each model. See the instructions for the binding procedures that are included with the receivers.
How many channels
A channel is the first thing to consider before buying. Usually 6-channel models are used and are popular with fans. Four channels are the minimum requirement for an RC toy, because even the simplest model will have to control some actions.
With a four-channel channel, you can perform four functions. For example, a channel to accelerate, a channel to move forward and backward, a channel to turn left and right and a channel to roll left and right. With more channels, you can perform more complex functions.
These days, even a common flight model has become a complex and require more channels to be controlled. More channels mean more operations, such as lighting systems, missed model alarms, retractable landing gear, flaps, sound systems, gyroscopes and gimbal. These additional features are not necessary, but if you want to enjoy your ride more, you can add them.
There are two different modes: mode one and mode two. Both modes have different settings. Mode one has the throttle control on the right joystick and the elevator control on the left. Mode two has the accelerator on the left joystick and the elevator control on the right, while the right joystick focuses on both axes and the left joystick focuses on the left/right and clicks the axes up / down.
There are switches that are used to control dual rates. When controlling the dual speeds, the sensitivity of the model is controlled during its flight. Two different amounts of control surface movements are defined for the swing, pitch and yaw axes which are referred to as high and low speed. Look for one that has a separate switch assigned to each axis.
Buy one with enough memory slots. Processor-based products are rapidly evolving and therefore it is necessary that you have one that can store a large number of profiles. If you buy a transmitter with only a few memory slots, you will need to update it very soon because of the changing demands.
Another important factor to consider is the servo-control that allows you to control the movement of the surface and the direction for the control input. There is a servo menu that allows you to change the address that the servo will define on a specific channel. If you ignore this fact, your device may crash during your first flight.
Whatever type of RC fan you are and whatever type of RC model you use, without a good remote control transmitter, the fun is incomplete. Whether it’s boats, cars, airplanes or helicopters, you will find that you have an important role in controlling these models. However, these days, helicopters, airplanes, gliders and quadcopters are in more demand and for this reason, they have been designed with the functionality of a flying device in mind.
All the above mentioned use the most advanced technology, but the best radio transmitter according to its characteristics and specifications is the Frisky Taranis X9D Plus. It is the most advanced as it is compatible with most channels and can be used to fly as many models as you want.
