Hi, I have calibrated my ESC’s and they all seem to throttle up fine. When I arm my hex and throttle up, the motors throttle up at different speeds. See screen shot. You will see motors 3 & 6 are running much lower then the rest.
Yes, Check the logs after you throttle up and see if RCOUT is giving those motors more. This will mean that the ESC are ok and the copter thinks its leaning or something.
Otherwise post the logs at just below half throttle and we will see what it’s doing.
