FLYROTOR 155A HV Brushless ESC (6–14S) – 30A BEC, USB + Bluetooth, Rotorflight Ready

Overview

Designed for 550–650 class helicopters stepping into high-voltage (6–14S) setups.

The FLYROTOR 155A HV ESC is a high-performance electronic speed controller built for demanding RC helicopters and large electric aircraft.

Built around a 32-bit RISC-V MCU running at 120MHz, it delivers fast response, precise governor control, and stable high-current operation.

Integrated USB-C and Bluetooth allow direct configuration without additional hardware, while advanced telemetry and a powerful SBEC make it ideal for modern Rotorflight, EdgeTX, and ETHOS ecosystems.
