Description

The Reflex Drive RD 4006 KV390 motor is engineered for demanding aerial platforms requiring high torque and efficient power delivery. Its 18N24P electromagnetic configuration provides smooth rotation and precise throttle response across the 4S to 6S voltage range, making it ideal for stable, heavy-lift flight profiles.

Constructed with a durable stator and high-grade magnets, the motor handles peak loads up to 27.5A and 660W, ensuring reliable performance during aggressive maneuvers or while carrying payloads. The 44.5mm diameter and 29.5mm height contribute to a high power-to-weight ratio, essential for maximizing flight time and agility in medium-sized drone builds.

Key Features

  • High-Torque 390KV Design: Optimized for 6S operation, providing excellent low-RPM thrust for efficient flight.
  • Robust Power Handling: Capable of 27.5A peak current and 660W peak power for demanding flight scenarios.
  • Efficient 18N24P Configuration: Delivers smooth, consistent torque with minimal cogging for precise control.
  • Optimized Thermal Design: Motor construction and winding technique promote effective heat dissipation during sustained operation.
  • Lightweight Durable Build: Weighing only 69g including cables, it offers a high-value performance-to-weight ratio for its class.
  • Versatile Mounting: Standard bolt pattern and shaft interface compatible with common medium-sized drone frames and propellers.

Applications

  • Medium-sized (7" to 10") cinematic FPV drones requiring smooth, stable footage.
  • Surveillance and monitoring drones built for extended flight times with payloads.
  • Heavy-lift quadcopters and hexacopters for agricultural or inspection applications.
  • Long-range exploration platforms where efficient 6S power systems are critical.

Frequently Asked Questions

What is the compatible voltage range for the Reflex Drive RD 4006 KV390 motor?

The Reflex Drive RD 4006 KV390 motor is designed to operate on 4S (14.8V) to 6S (22.2V) LiPo battery packs. Its 390KV winding is optimized for this range, providing high torque and efficient power delivery, making it suitable for applications requiring stable thrust across varying battery loads.

What size propeller is recommended for maximum thrust with this motor?

For the specified maximum thrust of 2.3kg, this motor is tested with 15x5.2-inch propellers. For optimal performance on 6S setups, we recommend using durable, medium-pitch propellers in the 15 to 16-inch diameter range, ensuring your electronic speed controllers (ESCs) are rated for the corresponding current draw.

Is this motor suitable for a heavy-lift cinematic or inspection drone build?

Yes, the RD 4006 KV390 is an excellent choice for heavy-lift applications. Its 390KV rating and 18N24P configuration provide smooth, high-torque output ideal for stabilizing larger platforms and payloads. With a peak power of 660W, it can support demanding flight profiles common in professional cinematography, agricultural spraying, or infrastructure inspection.

What is the motor's mounting pattern and shaft size?

While the exact bolt pattern and shaft diameter are not listed in the provided specs, motors in the 4006 size class typically feature standard M3 or M4 mounting holes. For precise integration, please consult the manufacturer's documentation or measure the provided unit to confirm compatibility with your frame and propeller hub.
