HobbyEagle A3 Pro 6-Axis Airplane Gyro & Stabilizer

The HobbyEagle A3 Pro is a powerful 6-axis gyro and stabilizer designed to give your fixed-wing aircraft smoother handling, greater precision, and a safety net when you need it most. Powered by a 32-bit MCU with a high-precision MEMS sensor, it combines fast response with reliable stability across a wide range of models and flying styles.

With six selectable flight modes, the A3 Pro adapts to your needs — from Normal mode for everyday stability, to Atti-Lock for crisp 3D manoeuvres, Trainer and Auto-Level for safe, beginner-friendly flight, and Auto-Hover for learning nose-up hovering. Gyro-Off mode is also available for testing or unassisted flying.

The unit supports standard, delta-wing, and V-tail aircraft, and works with most receivers including PWM, PPM, and Futaba S.Bus/S.Bus2 systems. Independent gain control is provided for aileron, elevator, and rudder, with remote master gain adjustment available via your transmitter. Setup is straightforward using the onboard button and LED menus, with options for servo trimming, travel limits, tilt calibration, wing type, mount orientation, and more.

Compact and lightweight at just 10g, the A3 Pro installs easily near the aircraft’s centre of gravity. It operates from 4.8V to 8.4V, supports servo frequencies up to 333Hz, and includes a protective capacitor for stable voltage. Whether you’re fine-tuning aerobatics, improving flight precision, or adding a safety layer for training, the A3 Pro delivers versatile stabilization in a simple, reliable package.
