Here Are Some General Features and Functions You Might Find in Such a System:

3-Axis Gyro: The "3-axis" refers to the gyro's ability to sense and control movement in three dimensions: pitch, roll, and yaw.

Flybarless System:, Unlike traditional RC helicopters that use a flybar for stabilization, flybarless systems rely on electronic gyroscopes to stabilize the aircraft.

Pro Version: The "Pro" designation often implies additional features or improvements over a standard version. This might include better sensors, advanced algorithms, or additional tuning options.

Voltage Range: The specified voltage range, in this case, 4.5~10V, indicates the acceptable input voltage for the gyro system.

Flight Control: These systems typically have various settings and adjustments that allow users to fine-tune the helicopter's flight characteristics according to their preferences and flying style.

Compatibility: Gyro systems are designed to work with specific types of helicopters and radio systems, so it's crucial to ensure compatibility with your particular setup.
