We try to keep our guides and descriptions as simple as possible, but sometimes we get a little carried away…
We collated a list of acronyms and definitions that you might find useful. Let us know if we’ve missed any!

2.4 GHz

A radio frequency in which control signals are transmitted from your radio controller to the quadcopter

5.8 GHz

A radio frequency used for transmitting camera footage from the quad.

Acro

Acrobatic. A ‘freestyle’ mode in which the gyro does not assist with levelling the quad.

Air Mode

A mode within betaflight which allows you to keep control of the quad even when throttle is at 0.

AUX

Auxiliary channel. A channel for which is auxiliary to the standard throttle, yaw, pitch, roll channels.

Band

A letter which is assigned to 8 video frequency channels. There are currently 6 bands in mainstream drone racing.

Bind

The process of matching the radio transmitter (controller) to the quad receiver.

BNF

Bind ‘and’ Fly. A quad that is ready to fly in all regards and requires a bind with a radio transmitter (controller).

CW / CCW

Clockwise / Counter-clockwise

ESC

Electronic Speed Controller. A circuit which converts flight controller output into motor input. Used only in Brushless motors.

Failsafe

A state in which the quad has lost contact with the transmitter and shutdown to prevent a fly away state.

FPV

First Person View. An onboard camera allows the quad pilot to view the drone’s movements from a stationary position.

Gyro

Gyroscope. A sensor in the flight controller which allows it to know what orientation it is in and keep the quad level.

LiPo

Lithium Polymer (battery).

LiHV

Lithium High Voltage (battery). A form of LiPo which is charged to a higher voltage than a standard LiPo.

mAh

milli-Ampere hours. A measurement of the energy charge in a battery. 1 milli-Ampere hour allows a discharge of 1 milli-amp for 1 hour.

PID

Proportional, Integral, Derivative. Three parameters which allow you to change the flight performance of a quad. Often tweaked in betaflight software.

Prop

Propeller. They come in a range of blade configurations.

Quad

Quadcopter. Referring to 4 motors.

RPM

Revolutions per minute. Usually referring to motor speed.

Rx

Receiver. Usually referring to a quad control receiver.

Thrust

Force generated by the motors and propellers. Measured in grams.

Tx

Transmitter. Usually referring to a quad controller.

VTX

Video Transmitter. A device which can transmit video feed on the 5.8GHz spectrum.
