Introduction

Thank you for purchasing the FETtec ESC. This is a high-quality sensor-less brush-less electronic 4 

in 1 speed control.

Features

Active current limiting @ 45A

Input voltage: 3S-6S

High quality 40V MOSFETs

STM32G071 @ 64MHz

128 kHz Motor PWM

Automatic input signal detection

Dshot 300-2400

PWM

OneShot 42/125

in development: Crossfire, OneWireBus, Sbus, Graupner HoTT

Soldering holes for up to 5 additional capacitors 

(required for 5S and 6S application)

KISS FC Passthrough

Betaflight Passthrough (in development)

Safety warning

Remove propeller before flashing and configuration!

The ESC can heat up to 100°C and more

Please ensure that there is enough space and airflow to prevent any damage because of 

overheating

Please check periodically for firmware updates in the FETtec Configurator
