A3 V2 3-Axis Gyro Flight Controller Stabilizer for RC Fixed-Wing Airplane and Copter - 4 Flight Modes, 3 Wing Types, HV Receiver Support, and One-Key Rescue for Beginner and Experienced Pilots
The A3 V2 is a 3-axis gyroscope and accelerometer flight controller stabilizer designed for RC fixed-wing aircraft and copter platforms, combining attitude stabilization, automatic levelling, and one-key emergency rescue functionality in a compact metal-housed 43 x 27mm unit weighing 11 grams. Built around a gyroscope rated at plus or minus 2000dps and an accelerometer rated at plus or minus 4g, the A3 V2 provides the sensor resolution and dynamic range required for responsive attitude correction across the full flight envelope of fixed-wing aircraft, from slow-speed stabilized training flights through to higher-speed aerobatic and delta-wing configurations. The wide 5-7.4V input voltage range and explicit HV (7.4V) receiver and steering motor support allow the A3 V2 to be integrated directly into high-voltage receiver systems without a separate voltage regulator or BEC, thereby expanding compatibility with modern HV servo and receiver setups common in mid-to-large-scale fixed-wing builds.
The A3 V2 supports 3 wing configuration types - standard, Delta-wing (flying wing), and V-tail - covering the majority of RC fixed-wing airframe geometries in active use, with the appropriate control surface mixing and stabilization axis assignment handled internally by the flight controller for each selected wing type without requiring external mixer modules or transmitter-side mixing configuration. Four flight modes covering Normal, Automatic-Balance, Auto-Hover, and Turn modes provide a graduated assistance framework from fully pilot-directed flight through to fully stabilized attitude hold, with one-key rescue and one-key crane functions providing immediate emergency attitude recovery at the press of a dedicated transmitter button. Remote total sensitivity control allows the pilot to adjust overall gyro gain from the transmitter during flight without landing, and independent adjustment of common sensitivity, self-stabilizing gain, and crane sensitivity gives experienced pilots precise control over each stabilization axis parameter. Three selectable servo operating frequencies of 50Hz, 125Hz, and 250Hz ensure compatibility with both standard analogue servos and higher-frequency digital servo setups across different airframe builds.
