Description

The Scorpion Tribunus A-4225-500kv V2 motor represents a pinnacle of engineering for high-performance UAV and large-scale RC aircraft propulsion. Its design focuses on maximizing electromagnetic efficiency through an optimized rotor magnet layout and ultra-thin 0.2mm silicon steel stator sheets, which minimize eddy current losses and heat generation under heavy loads. This results in a motor capable of sustained high-power output with remarkable thermal stability.

Built for longevity, the motor incorporates single-strand, high-temperature-rated copper windings and undergoes rigorous validation testing by professional pilots. The robust mechanical construction, including a 14-pole design and precision-machined components, ensures reliable operation in demanding environments where consistent thrust and power delivery are critical for platform stability and mission success.

Key Features

  • High-Efficiency Magnetic Design: Optimized rotor magnet layout and premium 0.2mm silicon steel stator laminations for minimal power loss and heat buildup.
  • Extreme Power Density: Capable of continuous 3104W output, making it suitable for heavy-lift drones and large-scale aircraft requiring significant thrust.
  • Professional-Grade Construction: Features high-temperature enameled copper windings and precision-balanced components for reliable, long-term operation.
  • Thermally Robust: Engineered to handle high efficiency currents up to 140A while maintaining structural integrity and performance.
  • Comprehensive Mounting Solution: Includes an A-42 cross mount, M4 bolts, thrust shims, and an M8 prop washer for secure and adaptable installation.
  • Direct Gas Engine Replacement: Specifically designed to match the power profile of 20cc to 25cc gasoline engines in RC aviation applications.

Applications

  • Heavy-lift cinematography and industrial inspection drones requiring stable, high-thrust propulsion.
  • Large-scale RC airplanes as a direct electric powertrain replacement for 20cc-25cc gas engines.
  • Enterprise UAV platforms for agricultural spraying, surveying, or cargo transport in the 8-15+ kg AUW range.
  • High-performance FPV and freestyle platforms where extreme power and efficiency on 6S batteries are paramount.

Frequently Asked Questions

What is the primary application for the Scorpion Tribunus A-4225-500kv V2 motor?

This motor is engineered for heavy-lift UAVs and large-scale RC aircraft requiring high torque and power. It is specifically designed as a direct electric replacement for 20cc to 25cc gasoline engines, making it ideal for platforms with an all-up weight (AUW) of 8 to 15+ kilograms, such as cinematography drones, agricultural sprayers, and large RC planes.

What ESC is recommended for this 500KV motor?

Given its maximum efficiency current of 140A and peak power over 3100W, a high-quality, high-current ESC is essential. We recommend using a compatible 6S-capable ESC rated for a continuous current of at least 150A-200A, preferably one with active cooling and robust firmware like BLHeli_32 or similar, to ensure stable operation and protect the motor's windings under full load.

What mounting pattern and propeller size does this motor support?

The motor includes an A-42 cross mount, which typically corresponds to a 42mm bolt circle diameter (BCD) mounting pattern. It uses an M8 propeller shaft. Suitable propeller sizes depend on the airframe and desired thrust, but for 6S operation at 500KV, large-diameter, high-pitch propellers (e.g., 18x10 to 22x12 inches) are common for achieving optimal thrust and efficiency in heavy-lift applications.
