Terms and Abbreviations

AP Aerial Photography, is the capability of a quadcopter in taking photographs or video of the ground from an elevated position.

Brushless Motor – Also known as electronically commutated motors, a brushless motor has permanent magnets which rotate around a fixed armature eliminating problems associated with connecting current to the moving part. The brushless motors are far more efficient and durable than brushed motors.

Controller – The handheld device that is used by the drone pilot to control the drone and the quadcopter. Controllers are also called transmitters.

Drone – This describes any unmanned aerial vehicle.

ESC – Electronic Speed Controller used to speed up and slow down the motor. The ESC can control separately each motor’s speed.

Flight control system – Is an interconnected network of controls which allows a pilot to fly a quadcopter or any other multi-rotor.  

FPV First Person View, also known as Remote Person View (RPV). The FPV system is based on a camera mounted on the quadcopter which lets the operator see what the aerial vehicle is seeing in real time.

GLONASS - Global Navigation Satellite System, is a networks of satellites orbiting the earth separate from GPS. Used to track movement or hold position, increases accuracy and coverage when combined with GPS.

GPS Global Positioning System is a networks of satellites orbiting the earth used to track movement or hold position.

Gravity Sensor Mode - Enables the quadcopter to automatically follow the way you move your smartphone. 

Gyroscope  A device that measures angular velocity and helps maintain orientation of the quadcopter while in flight. Usually quadcopters are using triple-axis gyroscope.

Headless Mode - Regardless of the orientation of the craft, the way the front of the craft is pointed, it will follow your stick movements.

Hexacopter  A common kind of small unmanned aircraft system (sUAS) that has six rotors oriented horizontally like a helicopter, usually using only the varying speed of the rotors (motors) to achieve both stability and direction of flight.

ICAO - International Civil Aviation Organization, International civil aviation governing body.

LOS   Line of Sight, refers to being able to see your drone from your operating position with your naked eye. Your drone should always be within your line of sight.

No Fly Zone – Areas where flying a drone is restricted by government regulations. Areas where a drone could interfere with an airplane or record sensitive information make up most of these areas.

OSD (On Screen Display)  of Live Data, displayed on the FPV monitor.

PID  - The proportional-integral-derivative controller or PID controller is the most common type of controller used for UAV stabilization and autonomous control.

Pitch – Simply describes movement up and down along the vertical axis from the front to the back of the drone.

Quadcopter  A common kind of small unmanned aircraft system (sUAS) that has four rotors oriented horizontally like a helicopter, usually using only the varying speed of the rotors (motors) to achieve both stability and direction of flight.

Roll – Is the rotation of the aircraft from front to back on a copter. Basically, it refers to the movement of the drone forward, backward, left and right along a horizontal axis.

RPAS - Remotely Piloted Aircraft Systems, is the official International Civil Aviation Organization (ICAO) term for drones. 

RTFReady to Fly. This means the drone is sold with everything needed in the pack. All you need to do is put it together, add batteries and you are ready to use it. It is possible you may need to buy the batteries separately. All of our drone are RTF including batteries unless otherwise specified.

sUAS  small Unmanned Aerial Systems, a term that generally describes battery-powered aircraft (quadcopter) with very low weight that can be picked up by one person.

UAS - Unmanned Aerial Systems

UAV Unmanned Aerial Vehicle (aerial or underwater vehicle), with no pilot on board. UAVs can be remote controlled aircraft or can fly autonomously based on pre-programmed flight plans guided by the onboard GPS system. These days, many are equipped with video cameras and FPV systems.

Waypoint Flight. waypoint is a set of coordinates that identify a specific point in physical space. Drones with waypoint technology typically utilize GPS and GLONASS to create waypoints.  As a drone pilot you can map a desired flight path with waypoints and specify the location and hover duration at each point. On some models you can also save the flight path, which enables you to complete very precise routes and fly repeat missions in the future.

YAW – This describes the quadcopter rotation around it’s center axis on a level plane.
