If you set both values to a positive percentage, switch up and switch
down, you can obtain two heading hold gain values in the same
fl ight program; for instance one value for hover (typically a higher
gain percentage) and one value for forward fl ight or 3D (typically less
gain). Again, it’s important to note that in Heading Hold the servo
arm will not center when you release pressure on the rudder stick.
We fi nd this to be the most common gain setup. That being said, 55%
to 60% gain is a good starting point.
If you have both percentages at a negative value the gyro will operate
in normal mode and also provide you with two possible “normal” fi ght
gain conditions. This is the least common gain setup.
If you choose, you can have the heading hold switch position (up)
and a normal switch position (down), with diff erent values at the
same time – a combination of the two gyro gain setups. Most call this
style of set up a “trim setup”; one can easily toggle from normal to
heading hold to review the installation and setup of the rudder servo.
