Faulty Banggood EMAX motors #6613684

Two furthest from camera do not spin. Left one is very very stiff and heats up when turned on. Right one I suspect is ESC issue.

currently have the same problem except 1 motor works. before i found that out i bought new cc3d board thinking i fried it and 4 new esc 12 amp emax simon series and the problem remained. maybe buy 1 new motor and see if you have same problem before you go buying new esc and board. the motors were brand new out of the box but the 1 good one works on all the esc;s. working on resolution let me know what you figure out. good luck
