- 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 68°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 6S LiPo batteries (22-25V range)
- Do not exceed maximum continuous current (35A @ 180s)
- Ensure proper battery discharge rates (C-rating)
Installation Safety:
- Follow torque specifications exactly
- Never exceed maximum bolt depth (5mm for motor mount and propeller mount)
- Verify rotation direction before propeller installation
- Maintain adequate clearance to frame
- Use proper size mounting hardware (M3)
Emergency Procedures:
- If motor overheats (>68°C), land immediately
- If unusual vibration occurs, stop operation
- If motor makes grinding sounds, inspect bearings
- Always have emergency landing plan
