🔧 Usage Notes

  • KV Selection Guidelines:

    • Freestyle/Cinematic ➜ KV 1300–1600 with 6S for responsive power

    • Endurance/Long Range ➜ KV 1000–1300 for high efficiency and low amp draw

    • Heavy Payload (Survey/Mapping) ➜ KV 900–1100 with 7S/8S for consistent lift

  • 2806.5 is considered a benchmark motor size for 7" long range due to its balance of thrust and efficiency.

  • 3115 and 3508 class motors are suitable for heavy-duty GPS drones, Li-ion pack builds, or commercial use.
