Description

The Scorpion Tribunus SII-4025-520KV brushless motor is engineered for precision flight in demanding aerobatic and industrial UAV platforms. Its design prioritizes efficient power conversion, translating 6S LiPo voltage into smooth, high-RPM thrust with minimal electrical losses. The motor’s advanced magnetic circuit and high-quality windings ensure stable torque delivery across the entire throttle range.

Built for durability, the motor incorporates a robust 5.98mm shaft and a 14-pole stator configuration to handle sustained high-power operation up to 2000W. The construction balances a lightweight 353-gram frame with the thermal mass necessary for dissipating heat under load, ensuring reliability during extended flight sessions and complex maneuvers.

Key Features

  • High-Efficiency Stator Design: Optimized magnetic circuit and winding technique minimize iron losses and maximize power output per amp.
  • Industrial-Grade Shaft: Precision-machined 5.98mm hardened steel shaft provides superior runout tolerance and bearing support.
  • Thermal Management: Motor housing and stator laminations are designed for effective heat dissipation during sustained high-load operation.
  • 14-Pole Low-KV Configuration: Delivers high torque and smooth rotation ideal for large propellers on 6S power systems.
  • Premium Build Quality: Utilizes high-grade bearings, magnets, and materials for consistent performance and extended service life.
  • Aerobatic & Industrial Tuned: Engineered specifically for the dynamic power demands and flight envelopes of advanced UAVs.

Applications

  • Heavy-lift and industrial inspection drones requiring high torque for large propellers.
  • Aerobatic and 3D fixed-wing UAVs demanding precise throttle response and high power.
  • Large-scale multirotor platforms (e.g., octocopters) for cinematography or payload delivery.
  • High-performance RC aircraft where smooth, reliable 6S power is essential.

Frequently Asked Questions

What is the recommended battery and ESC setup for this motor?

The Scorpion Tribunus SII-4025-520KV motor is optimized for 6S LiPo batteries (22.2V nominal). It requires a high-current ESC capable of handling its max efficiency current of 100A and peak power of 2000W. A high-quality 80-120A ESC with active freewheeling (AFW) is recommended for smooth operation and optimal thermal performance.

What size propeller is suitable for this 520KV motor on 6S?

On a 6S system, this 520KV motor is best paired with larger, high-pitch propellers typical for heavy-lift and aerobatic applications. Common sizes range from 15x5 to 18x6 inches, but final prop selection must be validated with thrust testing to ensure ESC and motor temperatures remain within safe limits during sustained operation.

Does the motor include a mounting system for standard drone frames?

Yes, the package includes a motor mount plate, a set of spacers, standoffs, and seven mounting screws. This hardware provides flexibility for adapting the motor to various frame configurations. The 49mm stator width typically corresponds to standard bolt patterns, but you should verify compatibility with your specific airframe's mounting holes.
