Some of the motors are not spinning up the same as others and I don't think the calibration was completed successfully.
Turn on your TX. Raise throttle to 100%. Switch on the FC while holding buttons 1 and 4. Wait for the beeps from the escs. As soon as you hear the beeps move throttle down to zero, you will hear one or more beeps. That's it. If not all of the motors spin up afterwards raise the minimum throttle to 20 in the misc settings of the FC, that should help.
