Overview
YARI 3-6S 35A ESC is designed for FPV, freestyle, and other high-performance multirotors that need a compact ESC with current-generation open-source firmware and digital motor-control protocols. It runs AM32 v2.21 firmware and is intended for builders who want configurable ESC behavior, firmware updates, and modern DShot workflows.
When used with YARI V6X or YARI V6S flight controllers, bidirectional DShot provides motor RPM feedback. This enables a dynamic notch filter to be configured in the flight-controller firmware, helping reduce motor- and propeller-related vibration in the control loop.
Compatibility notice: This ESC does not support collet-based motors, including A2212-style motors.
Configuration required: Configure the motor-pole count, KV, and other motor-specific settings in the AM32 Configurator before use. The ESC is not configured out of the box for every motor; consult the AM32 Configurator documentation for setup guidance.
Key Features
- AM32 v2.21: Latest open-source AM32 firmware for configuration, updates, and modern ESC features.
- Digital protocol support: DShot and bidirectional DShot support, alongside PWM.
- RPM-feedback workflow: Bidirectional DShot with YARI V6X and V6S enables RPM feedback and dynamic notch-filter configuration.
- Performance components: Automotive-grade Infineon OptiMOS 7 MOSFETs and an aluminium-alloy heatsink for demanding multirotor use.
- Motor-specific configuration: Use the AM32 Configurator to set motor poles, KV, and other required parameters before operation.
