Motor Testing under CLI

I keep seeing references to people using CLI to test motor and to test the spin of their motors.  But when I go into CLI and type Test, I don't see motor as one of the options.  I'm I missing something?  I'm running code 2.8.1.  I had a nasty crash I need to replace all 6 of my motors.


Thanks
Richard

    Thank you both.  I was getting really frustrated trying to find what I needed.  Having it under setup makes perfect sense.


    Thanks Again.

    Procedure:

    1) Connect usb port to APM, launch the planner and enter the CLI mode (do not connect the main motor battery for now!).

    2) Type "setup" and press "enter".

    3) Type "motors" and press "enter".

    4) Connect the main motor battery without disconnecting the USB cable, do not turn on your tx, is not important. Wait some second while APM initializes your esc.

    5) The motors will now spin in sequence, each motor will spin for less than 1/3 second at very low throttle and then stop, before the next motor will start after 2 seconds (3 with Y6 and X8). Please observe direction of rotation of each motor to ensure it is turning in the expected direction. First motor to spin will be the one located directly forward in the case of + configuration, or the first motor to the right of straight forward in the case of X configuration. The motor test will then proceed in a clockwise rotation. In the case of X8, it will spin the top front-right motor first, then the bottom front-right, and proceed around with the same pattern. OctoV will spin the front-right motor first, and then again, proceed clock-wise until reaching the front left motor.

    6) After the test pattern is complete, there will be a 4 second (5 with Y6 and X8) pause before beginning again.

    7) When you are satisfied that the motor pattern is correct, or you wish to stop the test, disconnect the main motor battery and then press any key to exit from test. Now if you want disconnect the usb port.
