Recommended Settings:
| Setting | Value | Why? |
|---|---|---|
| Protocol | DShot300 | Most stable |
| PWM | Enabled | Smoother throttle |
| Timing | 22.5° | More power |
| Protection | ON | Safety first |
| Startup | Sinusoidal | Smoother start |
💡 Tap "Save" (not "Save Config")!
🛠️ 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
