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 65°C for sustained periods
• Inspect motor bearings regularly for wear (critical for heavy-lift)
• Replace damaged propellers immediately
• Use propeller guards for heavy-lift operations near people

Electrical Safety:

• Verify correct ESC wiring before first power-up
• Use only 12S-24S LiHv batteries (48-72V range)
• Do not exceed maximum continuous current (81A @ 180s)
• Ensure proper battery discharge rates (C-rating)
• Use ESCs rated for 12-24S operation with FOC capability
• Monitor battery voltage during operation

Installation Safety:

• Follow torque specifications exactly (M5 bolts are critical)
• Never exceed maximum bolt depth (12mm for motor mount, 18mm for propeller mount)
• Verify rotation direction before propeller installation
• Maintain minimum 50mm clearance to frame
• Use proper size mounting hardware (M5 for motor, M4 for propeller)
• Ensure dual bearing configuration is properly seated
• Use high-strength threadlocker on all mounting bolts

Emergency Procedures:

• If motor overheats (>65°C), land immediately
• If unusual vibration occurs, stop operation immediately
• If motor makes grinding sounds, inspect bearings before next flight
• Always have emergency landing plan
• For heavy-lift operations, have redundant safety systems
