Dji F550 keep yawing to the left when hovering

[rcfanatics]

i just built a dji f550 and decided to do a test flight yesterday. it flew ok and everything so i decided to let it hover to just to check the gps lock but i notice after about 30-40 sec it keep wanting to yaw to the left without me touching the controls. i brought it down and recalibrate the compass but it made no difference, i even try turning the compass slightly to the left and right that help bit (i think) but it kept wanting to turn to the left. have anyone had this problem before or any suggestions? your help would be much appreciated thank you

One of your 3 clockwise rotating motors is not functioning as well as it should or the associated ESC is not 100%. Find the hottest motor or esc and replace it!
