quadrotors have frames that enclose the rotors, permitting flights through more challenging
environments, with lower risk of damaging the vehicle or its surroundings.

Components
Electronic Speed Controller (ESC)
: Regulates power to the motor according to the input throttle
level. It also pr5V power for the flight electronics
RC Receiver
: A (usually 2.4 GHz) RC radio receiver on the quadcopter that receives commands from
the RC transmitter on the ground. One way link
Telemetry Link
: A (usually 915 MHz or 433 MHz) bidirectional link between the flight controller and
ground station. Provides current status to the ground station and accepts flight commands to the
quadcopter.
RC Transmitter
: A (usually 2.4 GHz) RC radio transmitter used by the pilot to direct the quadcopter’s
direction and position.
Hub
: The central fuselage of the quadcopter. Contains the flight electronics and battery
Arm
: The beam that each of the motors sit on.
Generating Thrust
The motors and propellers alternate in direction and pitch, in order to cancel out and horizontal
torque. All propeller/motor combinations still produce downwards thrust:
