Brushless Speed Controllers

Scorpion Power System specializes in the design, development, and production of premium Brushless Electronic Speed Controllers (ESCs). Each ESC is designed in house by our team of passionate engineers. We not only design our own PCBs, but in addition we use our own proprietary motor control algorithms which have been perfected over the past 18 years to provide, powerful, efficient, reliable, and safe ESCs for your UAV or application. Each ESC undergoes rigorous QC inspection, and high current load testing, to ensure only the best products get delivered to you.

Our ESCs utilize all western components, sourced from reputable suppliers to ensure the best quality. They are manufactured and assembled predominantly in Taiwan from an experienced SMT manufacture to ensure the upmost reliability, and compliance with new security regulations. Further to ensure production capability even in the event of component shortages, and market situation, we stock in our warehouse up to 2 years supply of all critical ESC components. All components are rated to withstand extreme temperatures to handle demanding performance requirements. Housed in beautiful anodized CNC cases, which provides phenomenal heat dissipation, and gives a timeless aesthetic with a fit and finish which is second to none.

With an ESC and service of this caliber, you would expect to pay and ultra-premium price, but with our efficient manufacturing procedures, and streamlines distribution chain, Scorpion ESCs retail for very affordable prices, making them on of the best overall values on the market today. Combine that with our stable supply chain, customization options, and fantastic customer support, the value of choosing Scorpion Power System will be worth it every time

If you want to get ahead of your competitors you will need the best quality ESC available for an affordable price. The next time you need a brushless ESC, do yourself a favor and buy a Scorpion ESC. You will be glad you did!

Want your entire power system to be as powerful and reliable as the ESC is? Combine your Scorpion ESC with one of our Scorpion Motors to get a matched power system package that provides the power, efficiency, and reliability that your aircraft needs.

Tribunus Series / 6 - Step ESC

The Scorpion Tribunus Series of ESC are our premium Electronic Speed Controllers for driving Brushless Motors, with built in high strength HV BEC. 

These ESC use our proprietary 6-step motor control algorithm which has features such as Dynamic Timing, and Dynamic Frequency adjustment, ensuring they can operate any motor without user adjustment of settings. Further with our proprietary ultra fast switching technique we can drive even high pole count motor at high rpm with up to 240,000+ electrical RPM with ease.  

These ESC come with a wide variety of user adjustable protections such as Over Current, Over Temperature, Under Votlage, Capacity Cut Off, Phase Current, and De-Magnatization. Further they offer full telemtry read out via our UNSC protocol or other select protocols such as VBAR, Futaba, and Jeti, and data logging options.  

Legatus ESC - FOC / 6- Step

The Scorpion Legatus Series of ESC are our premium FOC Electronic Speed Controllers for driving Brushless Motors.

These ESC use our proprietary FOC control algorithm which in addition to working with any motor with very little setup and adjustment, they can provide market leading peak efficiency, high torque, and smooth operation. Further with our proprietary ultra fast switching technique we can drive even high pole count motor at high rpm with up to 240,000+ (6-step) / 160,000+ (FOC) electrical RPM with ease.  

They have wide range of thorttle input signals such as PWM, Multishot, One Shot, Dshot,/ DroneCAN / UAV Can / Serial.

These ESC come with a wide variety of user adjustable protections such as Over Current, Over Temperature, Under Votlage, Capacity Cut Off, Phase Current, and De-Magnatization. Further they offer full telemtry read out via Drone Can / UAVCAN / Unsolicited mode (serial)
