Friendly Reminder
Motor cores come in two versions: black and red.
- Original version = Black motor core
- New upgraded version = Red motor core
The red variant is the upgraded model with improved flame‑retardant performance.
If your black motor core malfunctions, replace it directly with a red motor core paired with red motor wires.
⚠️ Important Note:
Black cores are incompatible with red motor wires. Do not mix these two components.
