  How this one compares (quick sanity check)

  • 5000KV: coolest, torquey, safest

  • 6500KV: 🔥 sweet spot — fast but manageable

  • 8000KV: wild, hot, short-fuse motor

  Gearing advice (important)

  • Start small pinion / large spur

  • Check temps after 2–3 minutes

  • Keep motor under 70 °C (160 °F) for longevity

  • 2S + airflow = happy motor 😄
