Hobby Eagle A3 Pro 6-Axis Gyro Stabilizer for RC Airplanes

The Hobby Eagle A3 Pro is a 6-axis gyro stabiliser for RC fixed-wing aircraft, pairing a 3-axis gyro and 3-axis accelerometer with a 32-bit MCU. It helps beginners keep a trainer level and gives experienced pilots steadier tracking in gusty conditions.

Key features

• Six flight modes: Gyro Off, Normal, Lock, Angle, Level and Hover.
• Works with standard PWM receivers, single-line PPM and Futaba S.Bus/S.Bus2.
• Supports standard, delta (flying wing) and V-tail wing types.
• Independent gain for aileron, elevator and rudder, plus remote master gain from the transmitter.
• Sub-trim and travel-limit settings, configured through onboard button and LED menus.

Specifications

• Sensor: 6-axis MEMS (3-axis gyro + 3-axis accelerometer)
• Gyro range: ±2000 dps
• Accelerometer range: ±4 g
• Processor: 32-bit MCU
• Input voltage: 4.8 to 8.4 V
• Operating temperature: -10 to 50 °C
• Size: 43 x 27 x 14 mm
• Weight: 10 g (without wires)

It runs from the receiver supply, so a standard ESC BEC or a 2S receiver pack (8.4 V fully charged) is within range. Set the wing type and servo directions on the bench before the first flight.
