Talon 120HV: 50V 120-Amp Brushless ESC (CSE010013100)
The Talon HV 120 ESC is a high-voltage brushless speed controller designed for demanding RC helicopters and fixed-wing aircraft. It features a built‑in 20A peak BEC with selectable 6V or 8V output, accepts 3S to 12S LiPo packs, and delivers 120A of continuous current—up to 6000W of continuous power. The rugged aluminum enclosure helps keep temperatures in check during high-power bursts, and an optional 40mm cooling fan (sold separately; operates at 4.8–7.4V) can boost airflow in tight spaces.
Telemetry-capable and firmware-upgradable via Castle Link USB programming, the Talon HV 120 offers easy setup and real-time monitoring of essential data. It also includes power-system alerts to indicate overheating or overloading, helping protect the model and its electronics. With built-in BEC, broad voltage support, and reliable cooling, it’s a versatile choice for serious hobbyists building high-performance RC aircraft.

Overview
The Talon 120HV is a powerhouse brushless electronic speed controller, perfect for various helicopter and fixed-wing applications. It features a remarkable 120A continuous amperage capability and is designed to handle up to 6000W of power, thanks to its broad voltage input range of 3S to 12S LiPo.
This innovative ESC is equipped with a built-in 20A peak Battery Eliminator Circuit (BEC), providing selectable output voltages of 6V or 8V. This ensures efficient power distribution for your model while keeping it safe and operational. The sleek aluminum case helps maintain optimal temperatures during demanding situations, making it ideal for setups with restricted airflow.
The Talon 120HV also includes advanced power system alerts, using the motor to produce sound cues and LED flashing patterns to inform users about critical operating conditions such as over-temperature or excessive load. This feature greatly enhances the safety and reliability of your model during operation.
Telemetry capabilities allow users to monitor vital parameters such as battery voltages and ESC temperature, adding an extra layer of safety. Optional alarms can warn of receiver battery drain or interference, ensuring a more secure flying experience. To utilize telemetry, additional components like the Castle Telemetry Link must be purchased separately.
Users are granted free access to firmware updates through the Castle Link USB Programming Kit, enabling you to upgrade your ESC with new features and improvements as they become available. The programming kit is compatible with Windows operating systems, making it easy to customize your settings precisely according to your needs.
Designed for enthusiasts seeking high performance and efficiency, the Talon 120HV combines cutting-edge technology with reliable functionality, making it a top choice for hobbyists looking to elevate their flight experience.
