Check that the lever on the tail rotor is at right-
angles to the helicopter's longitudinal axis. If that
is not the case, adjust the pushrod.
e.
Check at both end-points of the yaw stick that the
adjustment range is adequate, and that the servo
does not strike one of the mechanical stops. Re-
connect the pushrod further in or out if necessary.
Setting the YAW input for the tail rotor
16.7.2.
There are two values for the yaw input. This makes it
possible to set up differential travels, i.e. different val-
ues for yaw to left and right. "Yawing" with or against
the direction of rotation of the main rotor produces dif-
ferent results, so the yaw input can be adjusted until
the subjective control sensitivity is the same in both
directions.
Moving to the Menu GIER:

YAW stick left
Use the yaw stick to select the value for right or left,
and set the value using the 3-D digi-adjustor.
A brief press
on the 3-D digi-adjustor concludes the
process. The flashing ceases, and the values are
stored.
Note:
Yaw input in heading mode -100% / 100%
If you operate a gyro in heading mode, the yaw stick
controls the angular velocity around the vertical axis.
The yaw input in the tail rotor automatically works over
the range -100% / 100%. Adjustments which may have
been made for normal operation (damping mode) are
ignored (but not changed).
Requirement for heading mode:
In the current flight phase you must activate heading
mode (menu: HEADG = 1) and set gyro gain within the
range -1 to -100% (menu: GYRO).
Important: use of flight phases
If you have activated flight phases (
can set different values for each flight phase. The flight
phases are selected using the A-ROT and PH
switches. The screen displays the currently selected
phase (

There are two parameters for COLLECTIVE PITCH,
allowing you to set different tail rotor compensation
rates for climb and descent. The tendency for the tail to
swing due to changes in main rotor torque when climb-
ing or descending can be corrected separately.
