In the “Swashplate” line of the “Base settings” menu
you have already defined the number of servos which
are installed in your helicopter to provide collective pitch
control; see page 82. With this information the transmit-
ter software automatically superimposes the functions
for roll, pitch-axis and collective pitch as required, i. e.
you do not need to define any additional mixers yourself.
If you have a model helicopter which only has a single
collective pitch servo, the “Swashplate mixer” menu
point is - of course - superfluous, since the three swash-
plate servos for collective pitch, pitch-axis and roll are
controlled independently of each other, i. e. no mixers
are used. In this case the swashplate mixer menu does
not appear in the multi-function list. With all other swash-
plate linkages employing 2 … 4 collective pitch servos,
the mixer ratios and directions are set up by default, as
can be seen in the screen shot above. The pre-set value
is +61% in each case, but the value can be varied within
the range -100% to +100% using the arrow buttons of
the right-hand touch-key, after touching the central SET
button of the same touch-key.
Simultaneously pressing the two arrow buttons or
of the right-hand touch-key (CLEAR) resets the
mixer input in the highlighted field to the default value of
+61%.
If the swashplate control system (collective pitch, roll
and pitch-axis) does not follow the transmitter sticks in
Swashplate mixers
Collective pitch, roll and pitch-axis mixers
the proper manner, then the first step is to change the
mixer directions (“+” or “-”), before you attempt to correct
the directions of servo rotation.
Note:
Ensure that the servos do not strike their mechanical
end-stops if you change the mixer values.
