Swash rotation
If the helicopter is adjusted so that the defl ections
for roll and/or elevation exploit the maximum travel
mechanically possible, e. g. for 3D helicopters, then
the total tilt applied to the swashplate if full roll and
elevation commands are applied simultaneously will be
considerably greater (141% in numerical terms). The
swashplate mechanism may then strike its endstops
and, in the worst case, the ball-heads could even be
disengaged.

In the mz-18 HoTT and mz-24 HoTT transmitters,
the relevant software function offers a limitation of the
swashplate defl ection that can be adjusted between any
combination of circular and square. That is, the limitation
of the overall swashplate defl ection or the swashplate
tilt angle can be limited between 100% (the defl ection
has a circular limit to the value achievable with roll or
elevation) and 200% (no effective limit) in the "SET"
line with the INC or DEC buttons at the right edge of
the display. In addition, the function can be completely
deactivated by selecting INH in the line "ACT".
Touch the RES button to reset a changed value in a
blue (active) value fi eld to the default value.
Swash rotation
With some rotor head controls, it is necessary to tilt
the swashplate in another direction than the intended
rotor plane angle during cyclical control. For example if
a four-blade rotor is used, it may be necessary to turn
the actuation 45° to the right or left with this menu item
so that the control linkage from the swashplate to the
rotor head can be precisely vertical. This allows the
blades to be controlled correctly without undesirable
differentiation. The controlling linkage then does not
have to be mechanically changed. Negative angles
equate to a virtual rotation of the rotor head to the left;
positive angles a virtual rotation to the right.
