* Soft-cut (also called Reduce Power) lets you know when the
quadcopter’s batteries are running low. If you set this to Cut-off/Shut
Down, your quadcopter will simply fall out of the sky when it reaches
a certain battery level.

2. Identify which edge of the chassis will be the front of your Elev-8 quadcopter. If you
have used the checkered stickers and/or the LED tapes, the front edge would be
between the two black-checkered, white-LED booms.
3. Put a piece of tape on the output shaft of each motor so that you can easily tell the
direction of rotation.
4. Connect an ESC’s 3-pin socket to the throttle port on your receiver.
5. Gently apply the throttle to see in which direction the motor turns. Refer to Figure
3.33 to identify the direction in which each motor needs to turn.
6. If the motor is not turning in the proper direction, disconnect any two of its leads,
reverse them, and reconnect.
7. Label the ESC with its motor position number, both on its case and on its 3-pin
socket.
8. Repeat with each ESC until all motors are turning in the correct direction and each
ESC case and lead are numbered.
