Help! Motor Twitching

[legoguy@mutarelli.com]

Hi, Can anyone help me with my motor twitching problem? When I give throttle my motor goes back and forth really fast. I am using an 1806 motor (pretty much the same that is in power pack A) and I am using an orange RX with the dx6e transmitter and a 12 amp esc with a 2s. The motor has plugs. I have checked that my screws have not touched the coils on the inside of the motor. I have tried calibrating my esc multiple times. And I just wanted to note that the twitching is inconsistent, sometimes it works and sometimes it does not.

Sounds like one of the three wires to the motor is either broken or has a bad solder joint. Could also be an internal break in the motor, or a bad ESC. Is the motor Soldered or does it have plugs?

Cheers!
