📌 Key Notes
- Each unit is factory balanced—no need for additional balancing.
- For high-power setups, remove the aluminum spinner cone to allow better heat dissipation.
- 12-blade EDFs draw significantly more current than traditional 5–6 blade units—use a wattmeter to monitor your power system.
- Suggested battery: 5000mAh 40C or higher for sufficient current delivery.
- ESCs should support at least 20% more than the peak current for safety margin and cooling.
