I have an R-SPEC MOTOR and it seems to not function properly. Originally it was very twitchy as seen in the video below. I have no disasembled my board and now the motor in question seems to work properly most the time using the blcd tool. However, when I turn it a little bit, the motor will shoot a spark and stop. Any idea if the motor is salvageable? it is an older model moto. I had read a post from onloop that said there could be extra coil in the motor that I could heat shrink.
