FPV refers to the immersive experience of flying a drone as if you were inside it. This is achieved through a live video feed sent from the drone’s camera to a pair of FPV goggles or a screen, allowing pilots to see what the drone sees in real time. This technology revolutionizes the drone experience, making racing and freestyle flying incredibly engaging.

Quadcopter (Quad):

The term “quadcopter” refers to a drone with four rotors, which is the most common design in FPV racing. Quads are popular for their stability, agility, and ease of control, making them ideal for high-speed racing and complex maneuvers.

Line of Sight (LOS):

LOS flying involves controlling the drone while visually watching it from the ground, without using FPV goggles. While this method is useful for initial training and safety, FPV is the preferred mode for racing because of its immersive and precise control capabilities.

RTF (Ready-to-Fly):

RTF drones come fully assembled and include everything needed to start flying immediately—often right out of the box. This type of setup is ideal for beginners who want to start flying without the hassle of assembling parts or purchasing additional components.

BNF (Bind-and-Fly):

BNF drones come fully assembled like RTF models but do not include a transmitter (controller). You’ll need to purchase a compatible transmitter and “bind” it to the drone, which involves linking the drone’s receiver to your specific controller.

PNP (Plug-and-Play):

PNP drones are similar to BNF models but also exclude the receiver, giving pilots the flexibility to add their preferred receiver and transmitter combination. This option is often chosen by intermediate and advanced pilots who have specific gear preferences.

Key FPV Components and Gear

In this section, we’ll cover the FPV drone racing terminology for the essential components and gear which form the backbone of any racing drone. When you’re ready to explore these parts in greater detail—understanding how each component impacts your drone’s performance—check out our detailed article, Drone Racing Components – An In-Depth Guide. It covers everything from transmitters and receivers to ESCs and VTXs, providing insights that will help you make informed decisions when building or upgrading your racing setup.

Transmitter (TX):

The transmitter, commonly referred to as the remote controller, is the device you hold in your hands to control the drone. It sends signals to the drone’s receiver, dictating movements such as throttle (altitude), yaw (rotation), pitch (forward and backward tilt), and roll (left and right tilt).

Receiver (RX):

The receiver is an onboard component of the drone that accepts signals from the transmitter. This communication is what allows the pilot to control the drone in real time. Receivers are typically specific to the type of transmitter being used, making compatibility an important consideration when building or buying drones.

Goggles:

FPV goggles are headsets that display the live video feed from the drone’s camera. They are one of the most defining pieces of FPV gear, providing an immersive, first-person perspective of the flight. Goggles vary in features such as resolution, field of view, and comfort, with higher-end models offering superior clarity and range.

VTX (Video Transmitter):

The VTX is a critical component that transmits the video signal from the drone’s camera to the FPV goggles. VTXs operate on specific frequencies and channels, and selecting the right settings can significantly affect signal clarity and range.

ESC (Electronic Speed Controller):

ESCs are responsible for controlling the speed of the drone’s motors based on the pilot’s commands. Each motor has its own ESC, and these components play a vital role in maneuverability and overall flight performance. Upgrading ESCs can result in faster response times and improved efficiency.

Flight and Control Terms

Throttle:

The throttle controls the power sent to the motors, directly affecting the drone’s altitude. Increasing the throttle will make the drone rise, while reducing it will lower the drone or bring it to the ground. Mastering throttle control is essential for smooth takeoffs, landings, and altitude maintenance during flight.

Yaw:

Yaw refers to the drone’s rotation left or right on its vertical axis. This movement is controlled by the left stick on most transmitters (mode 2 setup), allowing the pilot to turn the drone without changing its position in space. Yaw is frequently used during turns and aligning the drone with gates in racing.

Pitch:

Pitch involves tilting the drone forward or backward, influencing its movement in the forward or backward direction. This is controlled by the right stick on most transmitters, and managing pitch is critical for speed control and navigating racecourses.

Roll:

Roll refers to the drone tilting left or right, which shifts the drone laterally. It’s controlled by the right stick and is used extensively in maneuvers such as banking turns and maintaining a straight flight path.

Arming:

Arming is the process of activating the drone’s motors, preparing it for flight. When armed, the motors will start spinning at idle speed, and the drone is ready to respond to throttle inputs. Disarming the drone stops the motors and is an important safety measure when the drone is on the ground.

Tuning and Configuration Terms

Betaflight:

Betaflight is a popular open-source firmware used to configure, tune, and customize FPV racing drones. Pilots connect their drones to Betaflight Configurator, a software that runs on a PC, to adjust settings like PID tuning, rates, and other flight characteristics. Understanding Betaflight is crucial for optimizing drone performance.

PID Tuning:

PID stands for Proportional, Integral, and Derivative, which are values used in flight control algorithms to maintain drone stability. Tuning PIDs involves adjusting these values to find the right balance for smooth and responsive flight. Proper PID tuning can reduce oscillations, improve control, and enhance the overall flying experience.

Rates:

Rates refer to the sensitivity of the drone’s controls. Higher rates make the drone more responsive to stick movements, resulting in quicker flips, rolls, and turns. Lower rates provide smoother and more predictable movements. Rates are highly customizable and are often tailored to a pilot’s personal flying style.

FPV Video and Signal Terms

Band and Channel:

FPV systems operate on specific frequencies (bands) and channels within those bands. Common bands include Raceband, Fatshark, and ImmersionRC. Each band has multiple channels, allowing several pilots to fly simultaneously without video interference. Selecting the right band and channel is key to avoiding signal overlap with other racers.

Latency:

Latency is the time delay between the camera capturing video and it being displayed on the FPV goggles. Low latency is crucial in drone racing, as even a slight delay can affect reaction times and precision. Pilots often seek cameras and VTX systems that minimize latency for the best racing experience.

Interference:

Interference occurs when external signals disrupt the video feed, causing static or dropouts. This can result from overlapping frequencies, physical obstructions, or electronic noise. Managing interference involves careful selection of channels, proper antenna placement, and using high-quality FPV gear.

Safety and Race-Related Terms

Failsafe:

Failsafe is a safety feature that activates when the drone loses signal from the transmitter. In a failsafe event, the drone will automatically land or disarm to prevent uncontrolled flight. Setting up failsafe properly is essential for protecting both the drone and people in the vicinity.

Spotter:

A spotter is a person who assists the pilot by watching the drone’s flight path and surroundings, particularly during races or flights in crowded areas. Spotters are often required in competitive racing to ensure safety and compliance with regulations.
