• Mounting bolt security verification (M3 bolts)
• Locknut security on M5 shaft
• Brief spin test (listen for unusual sounds)

Periodic Maintenance Schedule

Every 10 Flight Hours:

• Re-torque mounting bolts to specification
• Check bearing smoothness (manual rotation)
• Clean motor exterior with compressed air
• Inspect propeller for wear or damage

Every 50 Flight Hours:

• Detailed bearing inspection
• Electrical connection integrity check
• Replace propeller if worn

Signs Requiring Immediate Inspection:

• Unusual vibration during operation
• Increased motor temperature (>80°C)
• Grinding or scraping sounds
• Reduced thrust output
• Propeller wobble

Bearing Replacement

Bearing Specifications:

• Type: Dual 685-2z
• Service Interval: 100-150 flight hours (typical)

Signs of Bearing Wear:

• Grinding or rattling sounds
• Increased vibration
• Shaft play or wobble
• Difficulty rotating by hand
• Increased operating temperature

Safety Notes

⚠️ Important Safety Information

Operational Safety:

• Never run motor without propeller attached for extended periods
• Ensure proper cooling during 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 4S-6S LiPo batteries (16-25V range)
• Do not exceed maximum continuous current (16A @ 180s)
• Ensure proper battery discharge rates (C-rating)

Installation Safety:

• Follow torque specifications exactly
• Never exceed maximum bolt depth (3.5mm for motor mount)
• Maintain adequate clearance to frame
• Use proper size mounting hardware (M3 for frame, M5 for propeller)

Emergency Procedures:

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