    I posted a video to show you what I have. I replaced all ESC boards and the motors. Everything powers up. I upgraded all software and did the calibration. It just falls over when trying to fly and the propellors fall off when they smack the ground.

    Any help? I am sure it is a newbie mistake, but I don't know what else to try

    Motors are all spinning counter clock wise from what I can see. Only two are supposed to run counter clock wise.

    You need to change the polarity in the two appropriate motors as depicted in image above.

    yep seems correct all 4 look to be spinning same ...... hence 2 props unwinding when touches ground.

    How do I fix the rotation of the motors? Is it simply a matter of changing the wires that I soldered to the ESC boards?

    Yes switch the positive lead with a negative lead as confirmed in this thread. viewtopic.php?t=

    I suppose you are referring the colors (red, black) of the motors wires?
    (video would not open for me)

    FYI: They do not represent polarity.

    Swapping any two of the three motor wires will reverse rotation.
    It is similar to a 3ph ac motor in this way.

    Do not reverse the polarity at the ESC DC input!

    Here's how the motor wiring should look. Click to enlarge photo.
