🔧 Key Features:

Full CNC Aluminum Construction: Shroud and rotor crafted from high-grade aluminum alloy for strength, precision, and heat dissipation.
Integrated Cooling Design: Shroud acts as a heat sink to cool the motor, improving efficiency and extending lifespan.
Dynamic Balance: Each rotor is dynamically balanced and tested for 8+ hours to ensure stable, vibration-free operation.
Anti-Blade Ejection Design: Safer and more reliable than plastic or carbon shrouds.
Modular Compatibility: Can be reassembled with other motors without compromising dynamic balance.
Pre-Assembled: Fan unit and motor come factory-assembled and balanced.

⚠️ Usage Notes:

ESC Compatibility: Only use JP Hobby ESCs with these EDFs (12-pole optimized). Using non-JP ESCs voids the warranty.
ESC Rating: Choose ESC with at least 20% headroom above max current draw.
Battery Recommendation: Minimum 5000mAh, 40C LiPo for short bursts (3–4 minutes WOT).
Safety First: Always use a watt meter to check amp draw. If draw exceeds factory specs, reduce timing or throttle via ESC.
Warranty is void if used outside of recommended setup.

✅ Quick Tips:

ESC Margin: Always choose an ESC with at least 20% headroom over the max current.
Battery Sizing: Use LiPos sized for 1/15 – 1/20 of expected max amp draw for 3–4 minutes full throttle.
Use Watt Meter: To verify your actual amp draw before flight.
Dynamic Balance: All units are dynamically balanced at factory – no extra tuning needed.
