Sometimes my mm will not make any noise...it is brand new. I just watch the led's if there is no sound
1. MBX-6 T8 1900KV, RX8 ON 4S
2. MBX-5T 1520, MMM ON 5S
3. MBX-5 ONROAD CONVERSION 1515, MMM ON 5S
4. MRX-3 ON ROAD CONVERSION 1512, MMM ON 6S
5. TEN T 2650 T8, MMP ON 3S
Mine doesn't make sound but it also doesn't run. From my understanding I think the sound comes from the motor and not the ESC. I tried connecting it to another motor I have lying around and still no noise and the motor doesn't spin. Also, I updated the firmware before I ran it. I also tried re-installing the firmware but still no luck.
