What kind of electronics are inside of Thruster motor?

Hi @leaf,

If you’re using our Basic ESC:

@EliotBR

The initial three beeps (rising in pitch) are the ESC detecting each phase of the connected motor. Once the phases are detected, the ESC initialises to arm itself, producing a low sound (when it detects a valid (1100-1900us pulse-duration) signal), followed by a high sound (when it detects a valid “stopped” (1500us pulse-duration) signal). Once all five beeps have occurred, the ESC is armed and ready to be controlled. There’s a visual display of this and the other possible beep sequences in the firmware manual in Technical Details / Documents on the Basic ESC product page.
