FLYROTOR 280A HV Brushless ESC (6–14S) – 35A BEC, USB + Bluetooth, 700–800 Heli

Overview

Built for demanding 700–800 class helicopters and high-power HV systems.

The FLYROTOR 280A HV ESC is a high-power electronic speed controller designed for 700–800 class RC helicopters and large-scale electric aircraft.

Powered by a 32-bit RISC-V MCU at 120MHz, it delivers extreme current handling, fast response, and stable governor performance in demanding setups.

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