INSTALLING MOTORS
Build Hopper
Hopper needs two types of motors, [A] and [C], that spin in opposite directions. [A] motors are identified by [WHITE] wires and [C] motors are identified by [RED] wires. [A] motors spin counterclockwise (sometimes called anticlockwise), or CCW, and [C] motors spin clockwise, or CW.
Steps to install motors:
Place the airframe and motors on your work surface so that the FTW Robotics logo is visible and is facing toward you.
Open one package of 2 [A] motors and one package of 2 [C] motors.
Lay the motors next to the airframe in the pattern shown in the image below. If the motors are not installed in the correct place, the drone will not fly correctly.
Thread a motor wire through the opening from the top of the airframe. Then, push the motor gently into the opening, leaving approximately ½ an inch of the motor exposed at the top.
Repeat Step 4 for all four motors (2 [A] motors and 2 [C] motors), making sure to follow the pattern shown in the image above.

Airfoil
A body (such as an airplane wing or propeller blade) designed to provide a desired reaction force when in motion relative to the surrounding air
Airframe
The Airframe is the main body of the drone that every other component attaches to
Anti-Clockwise [A]
Anti-Clockwise (or Counter Clockwise) [A] motion is one that proceeds in the opposite direction as a clock's hands
Battery
Energy source used to supply power to the drone
Clockwise [C]
Clockwise [C] motion is one that proceeds in the same direction as a clock's hands
Firmware
Firmware is permanent software programmed into a read-only memory
Gimbal
The mechanism that allows for different position of the camera on the drone
Micro-USB
a miniaturized version of the Universal Serial Bus interface which enables the direct charging of the drone's battery
Motor
A motor is powered by electricity that supplies motive power for moving parts
PCB
A Printed Circuit Board is a board design with a base board and copper traces to maintain connectivity between electronic components such as LED's, integrated circuits, and resistors for your devices
Propeller Twist
A differece in angle between the blade at its tip, and at the point where it meets the propller hub
Propellers
Mechanical device for propelling an aircraft or boat, consisting of a revolving shaft with two or more broad, angled blades attached to it
