Motor or ESC Issue? - EMAX Micro Brushless Kit

[jcocke5]

First off I'm new to the forums and the hobby in general. I figured the EMAX Micro Kit (Power Pack G) would be a good place to start. I purchased it when they were first released (before the Gremlin frames were released so I printed my own design) and with the help of youtube and google got everything together nicely...I think I'm hooked on this hobby now

It flew great for 5-6 flights but now I'm having issues with one of the motors just jerking and studdering. The issue is there when I control it via Cleanflight and the TX. I'm thinking this is either the ESC or the motor but I'm not sure how to determine which. I didn't crash it either so that also adds to the confusion. Any suggestions to troubleshooting would be awesome.

First place to look is the motor to ESC connections, jerking and stuttering is usually caused by one bad connection of the 3 motor leads. If they all look good, you can try swapping the motors around and see if the problem follows the motor or the ESC.
