What is gyro gain?
This refers to the sensitivity of the gyro. When the gyro senses an unwanted movement it commands the tail servo to move in the opposite direction to compensate. How much it tells the servo to move is the ‘gain’. Ideally the amount of gain should match how much the helicopter was rotated so that it stays pointed in the same direction and does not move. If the gain is too high then the helicopter over compensates. The effect you will see is the tail will bounce back and forth. If the gain is not enough then you will notice the tail does not hold very well. When setting the gain, you want to turn it up until you see the tail ‘hunt’ (bounce back and forth) then turn the gain back down until it stops.
