Description

The Scorpion Tribunus HK5-4026-1115KV brushless motor represents the fifth generation of Scorpion’s high-performance HK series, engineered specifically for demanding 550–580 class multirotor and helicopter platforms. Its design prioritizes electrical efficiency and thermal dissipation, enabling sustained high-power operation on 6S LiPo batteries.

Advanced cooling is achieved through a combined internal axial fan and an external centrifugal fan, which work in tandem to force air through the motor’s core, significantly lowering operating temperatures under load. This thermal management, coupled with the motor’s optimized magnetic circuit, results in exceptional torque-per-amp efficiency and extended service life in intensive UAV applications.

Key Features

  • HK5 Series Fifth-Generation Design: Incorporates advanced materials and magnetic optimization for peak efficiency and power density.
  • Dual Active Cooling System: Integrated internal axial fan and external centrifugal fan dramatically improve airflow and heat dissipation.
  • High Torque-per-Amp Efficiency: Delivers powerful thrust and responsive control while minimizing current draw and heat generation.
  • Robust Mechanical Construction: Features a precision-machined 6x32mm shaft and high-grade bearings for reliable operation under heavy loads.
  • Optimized for 6S LiPo: Engineered to deliver up to 4050W, making it ideal for large-scale multirotor and helicopter platforms.
  • Low No-Load Current: At just 3.5A, the motor exhibits excellent magnetic and mechanical efficiency from a standstill.

Applications

  • Heavy-lift and cargo UAV platforms in the 550–580mm frame class.
  • Large-scale FPV and aerial photography drones requiring high-torque, efficient propulsion.
  • RC helicopter conversions and scale models designed for 6S power systems.
  • Industrial inspection and mapping drones where reliable, high-power motor performance is critical.

Frequently Asked Questions

What is the primary application for this Scorpion HK5-4026 motor?

The Scorpion HK5-4026-1115KV motor is engineered primarily for 550–580 class multirotor drones and RC helicopters. Its high torque and 4050W power rating on 6S LiPo make it ideal for heavy-lift UAVs, aerial photography platforms, and scale helicopter models requiring efficient, high-power propulsion.

How does the dual-fan cooling system work?

This motor features an integrated internal axial fan and an external centrifugal fan. The axial fan pulls air through the motor's core, while the centrifugal fan, driven by the motor's rotation, expels hot air outward. This combined forced-air convection significantly improves heat dissipation, allowing for higher sustained power outputs and longer motor life.

What is the maximum recommended battery configuration?

The motor is optimized for 6S LiPo battery systems (22.2V nominal), where it delivers its rated 4050W peak power. The specifications also list compatibility up to 12S, but operation at higher voltages requires careful propeller selection and thermal monitoring to avoid exceeding the motor's electrical and thermal limits.

What size propeller and ESC are recommended for 6S use?

For 6S operation on a 550–580mm frame, typical propeller sizes range from 15x5 to 17x5.5 inches, depending on the desired thrust and efficiency. A high-quality 80A-100A electronic speed controller (ESC) with active freewheeling is recommended to handle the motor's potential current draw and ensure smooth, reliable throttle response.
