• Check bearing smoothness (manual rotation)
• Clean motor exterior with compressed air
• Inspect propeller for wear or damage

Every 50 Flight Hours:

• Detailed bearing inspection
• Shaft runout measurement
• Electrical connection integrity check
• Replace propeller if worn
• Document maintenance in flight log

Signs Requiring Immediate Inspection:

• Unusual vibration during operation
• Increased motor temperature (>121°C)
• Grinding or scraping sounds
• Reduced thrust output
• Propeller wobble

Bearing Replacement

Bearing Specifications:

• Type: Single 61803- 2z Sealed
• Service Interval: 100-150 flight hours (typical)
• Replacement Procedure: Contact technical support or refer to motor maintenance procedures

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 (causes unbalanced load)
• Ensure proper cooling during extended operation
• Monitor motor temperature - do not exceed 121°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 (12.69A @ 180s)
• Ensure proper battery discharge rates (C-rating)

Installation Safety:

• Follow torque specifications exactly
• Never exceed maximum bolt depth (7.5mm for motor mount and 8mm for propeller mount)
• Verify rotation direction before propeller installation
• Maintain adequate clearance to frame
• Use proper size mounting hardware (M4)

Emergency Procedures:

• If motor overheats (>121°C), land immediately
• If unusual vibration occurs, stop operation
• If motor makes grinding sounds, inspect bearings
• Always have emergency landing plan
