GRAUPNER mc-32

Program description - Helicopter type
Symmetric three-point control as described above
but radially offset by 90°, one lateral roll servo and
two pitch-axis servos, front and rear.
• “4Sv (90°)”
Four-point swashplate control affected by two roll
servos and two nick servos.
Simultaneous tap on the  or  keys of the right
four-way button (CLEAR) will reset the option back to
“1 Servo”.
Note:
Except for the “1 Servo” choice, swashplate
mixer proportions must also be set in the
»Swashplate mixer« menu, page 223.
Swashplate linearization

The "yes" entry will prevent undesired side effects
such as pitch change due to a roll function or tension
between swashplate servo rods.
This type of tension can arise when effected servos
strain for different displacement positions due to travel
which deviates from one another.
Linearizing will require a bit of familiarization on the
part of the pilot because, in order to linearize the
entire rotation travel of the servo arm, servo travel
is reduced in small control movements – similar to a
pronounced exponential setting.
Rotor direction
After selecting the “Rotor direction” line with the 
selection keys of the left or right touch pad, the entry
field will be framed.

After a tap on the centre SET key, the main rotor's
direction of rotation is entered in the “Rotor direction”
line with the selection keys of the right touch pad:
"right": The main rotor turns clockwise when viewed
from above.
"left": The main rotor turns counter-clockwise
when viewed from above.
A simultaneous tap on the  or  keys of the
right touch pad (CLEAR) will set the option to "right".
