DYS Aria AM32 / BLHeli_32 35A 70A 3-6S Brushless ESC for FPV Racing Drones, Fixed-Wing Aircraft & RC Cars

Overview

The DYS Aria AM32 / BLHeli_32 Brushless ESC is a compact and high-performance electronic speed controller designed for FPV racing drones, fixed-wing aircraft, multirotors, and RC car applications. Available in 35A and 70A versions, this ESC supports 3-6S LiPo input and is optimized for fast throttle response, stable motor output, and reliable performance in demanding RC setups.

Built with a 32-bit ARM Cortex MCU STM32F051 48MHz processor, the ESC provides precise throttle control with a 2048-step resolution, strong anti-interference capability, and support for modern digital throttle protocols such as DShot150, DShot300, DShot600, and DShot1200.
