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 63°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 (52A @ 180s)
- Ensure proper battery discharge rates (C-rating)
Installation Safety:
- Follow torque specifications exactly
- Maintain adequate clearance to fuselage
- Ensure M10 left-hand thread nut is properly secured against rotation
Emergency Procedures:
- If motor overheats (>63°C), land immediately
- If unusual vibration occurs, stop operation
- If motor makes grinding sounds, inspect bearings
