Choosing the Best Transmitter for a Racing Drone

A radio transmitter or TX is a device that allows drone pilots wirelessly control their drones in the air. Before you purchase any racing drone this is one of the many important things you ought to factor in your decision. Choosing the best transmitter for a racing drone can be quite demanding considering the many factors involved. To make this easy, the following are some of the factors you should give priority to.

1. Video Transmission Frequency

Basically, this is one of the most important factors to consider when choosing the best transmitter for your racing drone. Most transmitters come in four different frequency bands which are:

  • 900 MHz
  • 2 & 1.3GHz
  • 3 & 2.4 GHz
  • 8GHz

Note that the lower the frequency of your transmitter, the better it is for its signal to penetrate through objects. Therefore, if you are planning to compete in drone racing involving flying around objects, the best transmitter to go for is a 900MHz. The reverse is true when it comes to higher frequencies.

The second thing to take into account when choosing a transmitter is the frequency in which your radio system runs on.

The rule of the thumb here is that “You should never at any given point in time transmit your video on the same, close to or multiple harmonic of the frequency your radio system uses.” By adhering to this rule you will help prevent frequency interferences thereby giving you the best flight experience.

2. Transmitter Power

Power is yet another important factor to consider when choosing a transmitter for your racing drone. Usually, when choosing a transmitter for your drone it is always advisable never to go beyond the 500 to 600 mW maximum. When it comes to FPV drone racing the ideal transmitter power to go for is always a 200mW. Note, the higher the transmitter power the more heat it generates which resultantly creates a lot of interferences during flight.

3. Hardware and Features

When choosing your drone’s transmitter, the hardware and other features are important in influencing your decision. In addition to choosing a transmitter with a good display screen resolution, you may want to consider a transmitter that is made from a quality material as this will help it withstand the harsh atmospheric conditions.

In terms of software additions, you may want to consider a transmitter with a programmable firmware in order to enhance your flying experience.

4. Budget Considerations

For most transmitters, the price ranges between $20 and over $100 depending on the racing drone brand & transmitter power. As with most products price is always directly proportional to quality, therefore, the cheaper the transmitter the lower its quality is.

However, if you are running on a tight budget or you are trying out your flying skills, it is advisable to start with a low-quality transmitter and upgrade to better and costly transmitters as time goes by.

A good transmitter is most definitely a long-term investment. With the above factors under considerations, take your time and select the best transmitter for your drone racing events and for sure improve your racing experience.
