🛠️ Troubleshooting
| Problem |
Fix |
| Motor won't start |
Verify signal wiring; calibrate throttle range; check motor direction. |
| Motor jitter/oscillation |
Disable bidirectional DShot; validate KV/pole settings; reduce PWM frequency. |
| ESC gets hot |
Check load (sustained current > rated); improve cooling or lower throttle curve. |
| Telemetry data loss |
Confirm TX/RX wiring; enable "ESC Sensor" in Betaflight. |
⚠️ Safety First!
- Always remove props when testing!
- Set voltage cutoff (3.3V/cell) to prevent battery damage.
- Do pre-flight checks
