Tail gyro response

In addition to the gyro gain adjustment there is a parameter called gyro response which helps to optimize the precision of the gyro. Increasing the gyro response will cause a harder stop and quicker response to rudder stick inputs. But if the response is too high, the tail will bounce back after a hard stop and feel spongy when making fast direction changes. If the response is set too low on the other hand, the rudder control feels dull and stopping might be too soft. Ideally the tail should stop perfectly to the point without making any flapping noises.

Before adjusting the gyro response make sure the maximum possible tail gyro gain has already been determined as described above! The gyro response can be considered as some sort of fine-tuning and adjusting this parameter will not have any significant effect if the gyro is not operating correctly in general. Also note that after adjusting the tail gyro response you may have to readjust the tail gyro gain once again, as these parameters interact to each other.

For better tail gyro performance also check for correct servo horn length. If you can only set the gyro gain to a very low value and the rudder tends to oscillate very easily, move the linkage ball further inwards to the center of the servo horn. If on the other hand you have a very large amount of gain and the gyro still does not seem to be capable of holding the tail rotor in any flight condition, move the linkage ball on the servo horn further out from the center, to get faster response speed when the gyro controls the rudder servo. Also you may use different (larger) tail rotor blades or higher tail rotor speed to achieve better holding force.
