Expert mode Yes
As soon as the "Expert mode" option on the last line of the display
page "Basic setting control" is set to "Yes", further options are avail-
able on the display pages "Swash setting" and "Tail rotor settings".
Regardless of "yes / no", however, the associated settings are always
effective. Switching to "no" thus does not switch off these options,
but only fades them out again.

The "P tail" option is responsible for effecting a harder stop with the
tail. Higher values result in a faster stop. If the P values are too high,
the tail will start to "oscillate". In such cases, the value must be
reduced again.
Adjustment range: +40 … +125
I tail
The I-factor ensures constant pirouetting. Start with low values and
only increase them until the pirouettes are constant. If the values are
too high, this will cause the tail to oscillate slowly.
Adjustment range: +20 … +100
D tail
The D-factor influences how the tail is stopped. If the tail bounces
somewhat when the tail is stopped, this parameter should first be
increased in 5-degree increments to test the tail stop.
Adjustment range: 0 … +50
Note on "P / I / D tail"
The control is based on the PID principle, where the "P" stands for
"proportional", the "I" for "integral" and the "D" for "digital". In short
...
... the deviation from the setpoint proportional to the manipulated
variable has an effect at the P value.
... the existing control deviation is continuously summed up at the I
value and then acts on the manipulated variable via the I value.
... the differential component only takes into account the speed of
the control deviation and then acts on the control accordingly via the
D component.
Pitch => Tail and Swp => Tail
Torque compensation for pitch and tail is optimal when the two
options are adjusted together.
• Pitch => Tail
With rapid successive pitch changes (pitch pumping) and the
resulting swashplate movements, the tail should remain stable
also during the load. If the tail swings out shortly, "Pitch => Tail"
should be increased until the tail is still.
