Motors out of sync

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.

Any ideas what causing this?


Looks like its trying to yaw, but assuming your yaw input is channel 4 it looks ok in your pic.

If the FC is not perfectly level when you increase throttle they motors will not spin up at the same time.
Check the horizon on the Flight Data page.

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.
