Safety Notes

⚠️ Important Safety Information

Operational Safety:

• Never run motor without propeller attached (causes unbalanced load)
• Ensure proper cooling during extended operation
• Monitor motor temperature - do not exceed 80°C for sustained periods
• Inspect motor bearings regularly for wear
• Replace damaged propellers immediately

Electrical Safety:

• Verify correct ESC wiring before first power-up
• Use only 12S LiPo batteries (44-50V range)
• Do not exceed maximum continuous current (30A @ 180s)
• Ensure proper battery discharge rates (C-rating)
• Use ESCs rated for 12S operation with FOC capability

Installation Safety:

• Follow torque specifications exactly
• Never exceed maximum bolt depth (5mm for 170/340KV, 8-10mm for 150KV mounts)
• Verify rotation direction before propeller installation
• Maintain minimum 20mm clearance to frame
• Use proper size mounting hardware (M4 for motor, M3 for propeller)
• Ensure triple bearing configuration is properly seated

Emergency Procedures:

• If motor overheats (>80°C), land immediately
• If unusual vibration occurs, stop operation
• If motor makes grinding sounds, inspect bearings
• Always have emergency landing plan
