For the steering control left/right also
choose the control type [Normal]. The
1. assignment should be assigned to the
left motor, the 2. assignment to the right
motor. Only for the right motor adjust the
efficiency rate [Rate right] to -100% and
the [Rate left] to +100%. You can further
improve the driving by setting the driving
control function [Expo] to -20%, slow
down the steering with [Filter] and
decrease [Rate left / right].

Emergency off
- useful if several func-
tions need to be shut off with the push of
a button e.g. drive and pump. Choose
the control type [
Emerg. off
] for the
softkey pair you want. You can connect
up to three servo channels with the
assignments of these softkeys. If you
press [Emerg. off] all three channels
react according to their channel type.

Two steering servos with different
travel radius:
Choose the channel type
[Servo] for both steering servos.
Tip:
Assign names to both channels,
e.g. Front and Rear.
Set the right direction of rotation in the
channel menu with [Reverse] for both
servos. Choose the control type
[Normal] for the steering controls. For 1.
assignment choose the channel for front
steering, for 2. assignment the channel
Typical applications:
Ÿ
Mixer for controlling the rpm of a
hydraulic pump:
Choose the servo
channel type [Pump] for the channel that
is connected to the speed controller
(ESC) of the pump (channel type
depending on your ESC, see chapter
Menu Servo). For all channels that
control hydraulic valves choose the type
[Valve]. For the assigned controls the
1. assignment should operate the
hydraulic valve, the 2. assignment the
pump.
By changing the efficiency rate [Rate
down], [Rate up] or [Rate left], [Rate
right] you adjust how much the pump
rpm increases when operating the
hydraulic valve.

Cross mixer for steering a tracked
vehicle
with separate motors for
left/right and two ESCs: Choose channel
type Motor for left and right ESC
channel.
Tip:
Give them significant names e.g.
Left and Right.
Choose the control type [Normal] for the
control channel (throttle) for driving
forwards and backwards. Assign the
1. assignment to the channel for the left
motor and the 2. assignment to the right
motor. If you accelerate now (throttle up)
both tracks should drive forward. If not
switch the direction of rotation for the
servo channels with [Reverse].
The Zwo4 radio offers a universal and clear
concept:
Each control element can
control up to four servo channels - one
servo channel can be controlled by any
number of control elements
. All necessary
settings are available as presets with the
controls, therefore there is no special mixer
menu.
If you assign several controls to one servo,
the servo channel type defines how they are
mixed.
