QPT 4720 Drone Motor

Original price was: ₹5,499.00.Current price is: ₹4,499.00.

Designed for large-scale multi-rotor UAV platforms, such as heavy-lift drones and professional industrial aircraft including FPVs. Suitable for AUM of 6-16 Kgs in Quad Conf.

Primary Use Cases

  • Heavy-Load Aerial Photography: It provides the stable high thrust needed for carrying professional cinema cameras, gimbals, and LiDAR systems.
  • Industrial Inspection & Security: Its high efficiency makes it ideal for long-duration missions like power line inspections, substation patrols, and high-rise facade monitoring.
  • Logistics & Delivery: Suitable for multi-rotor platforms carrying payloads between 3–5kg.
  • Long-Endurance VTOLs: Often used in Vertical Take-Off and Landing (VTOL) fixed-wing platforms where high cruise efficiency is critical.
  • Agricultural Drones: Provides the necessary torque for mid-sized spraying or plant protection drones.

Key parameters

  • Voltage Support: Typically operates on 6S to 12S LiPo
  • Max Power: Can reach peak outputs between 1500W and 3000W depending on the specific manufacturer’s winding.
  • Thrust: Capable of generating maximum thrust levels around 8.5kg
  • Propeller Compatibility: Optimized for large propellers ranging from 13 to 18 inches, including three-blade configurations like 15x7x3.

Recommendations

 ESC: Best paired with high-voltage ESCs rated for 80A.

Props: Large carbon fiber propellers, such as 15″ or 16″ models, are recommended to maintain peak efficiency
