JP Hobby 105mm 12-Blade CNC Metal EDF System with Motor

🌀 JP Hobby 105mm 12-Blade CNC Metal EDF System with Motor JP Hobby’s high-performance 105mm EDF fan system is precision CNC-machined from aluminum alloy. Designed for serious RC jet enthusiasts, this unit comes pre-assembled with a powerful MT-4250 outrunner brushless motor and is dynamically balanced for optimal performance. 🔧 General Specifications Fan Diameter (Inner / Outer): 105mm / 107mm Exhaust Outlet Diameter: 105mm Blade Count: 12 high-efficiency blades Stator Blades: 8 (fixed) Material: Full CNC aluminum alloy Motor Type: MT-4250 Outrunner Brushless Motor (12-pole) Motor Size: Φ50mm x 80mm (total with fan) Shaft Diameter: 6mm or 8mm (depending on version) Weight: ~545g - 550g (including motor) Rotation Direction: CCW (Counter-Clockwise) Connector Type: 5.5mm PK Bullet Motor Cone: Removable (recommended to remove for high-power setups to improve cooling) Battery Motor KV Amps (Peak) Thrust (kg) Power (W) Recommended ESC Weight 6S (22.2V) 1400KV N/A N/A N/A 150A LV 545g 8S (29.6V) 1150KV 119A 5.0kg 3522W 150A HV 550g 8S (30.0V) 1150KV 125A 5.4kg 3763W 150A HV 550g 8S (32.0V) 1150KV 134A 5.8kg 4288W 160A HV 550g 10S (37.0V) 1000KV N/A N/A N/A 150A HV 550g 12S (44.4V) 875KV N/A N/A N/A 160A HV 550g 14S (51.8V) 840KV N/A N/A N/A 160A HV 542g 📌 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.
