What is a Gyro?
It is a device used to sense sudden unwanted movements of the tail. It’s job is to move the tail servo to compensate for the unwanted movement. As an example, lets say you are in a hover and a sudden gust of wind blows the right side of the helicopter. Without a gyro this would cause the helicopter to turn to the right. With a gyro, it very quickly senses the sudden movement and gives a left command to the tail servo to keep the helicopter pointed where it was. This is just a simple example, the real benefits of a gyro come into play during aerobatics.
