Product details
The Componentas KOS60 is a compact 4-in-1 electronic speed controller designed and manufactured in the Czech Republic for FPV drones, interceptor platforms, and tactical multirotors. Built around an STM32G071 microcontroller with Infineon MOSFETs and running open-source AM32 firmware, it delivers 60 A continuous and 75 A peak per channel across a 3S to 8S battery range. The KOS60 is engineered with a fully traceable, NDAA-compliant bill of materials to meet the supply chain requirements of European and allied defense procurement.
Key Technical Features:
- NDAA-compliant BOM: Every component sourced from allied countries. STM32 MCU (ST Microelectronics), Infineon MOSFETs, PCB and assembly in Czechia. Ready for US and EU defense procurement reviews.
- Open-source firmware: AM32 out of the box with full access to throttle response tuning, motor timing, braking, and protocol selection. No proprietary lock-in, no per-unit licensing.
- Bidirectional telemetry: DShot 600/300/150 with bidirectional support for real-time RPM feedback. Extended DShot Telemetry (EDT) provides voltage, current, and temperature back to the flight controller.
- Robust power stage: 6-layer PCB with heavy copper weight, designed for repeated full-power runs and high-duty mission profiles.
- Wide battery compatibility: 3S to 8S LiPo or LiHV (9–35 V), suitable for compact interceptors through to larger tactical multirotors.
- Compact signal interface: JST-SH 10-pin connector (1 mm pitch) combines motor signals, telemetry, and battery rail in a single cable.

What does an ESC do?
The ESC (Electronic Speed Controller) is the brain of the electric propulsion system. It regulates the current sent to the motor phases to achieve the required speed and torque. It also includes key protection features such as overcurrent, undervoltage, and overtemperature safeguards to prevent damage to the motor and power electronics.
How is the ESC controlled?
The ESC can be controlled by a flight controller, an autopilot, or directly by a transmitter or throttle signal. The most common control interfaces are PWM, CAN, and UART. PWM is simple and widely supported, while CAN and UART enable two-way communication for telemetry, configuration, and advanced diagnostics.
What happens if the ESC overheats?
Most ESCs monitor temperature via internal sensors. If protection is enabled, the ESC will reduce power or shut down. Without thermal protection, overheating can damage MOSFETs or capacitors and permanently destroy the controller.
How to prevent ESC overheating?
Provide adequate airflow or liquid cooling, depending on the ESC design. Avoid overloading the motor, since excessive current directly increases ESC temperature. Ensure correct propeller size or load and verify that wiring and connectors can handle the rated current.
What maintenance does an ESC require?
ESCs are maintenance-free. Keep them clean and dry. Use compressed air to remove dust, and check connectors periodically for corrosion or loose pins. Always make sure the ESC firmware is up to date.
