1.3 Positioning and fixing parts
Camera:
◦Mount on a stable base, which doesn't move or resonate
◦The camera should have a free sight, with no parts in front
of the lens
◦Do not place the camera in a position where it can be
damaged when the model hits an obstacle
◦Secure the plastic clip of the camera with included cable tie
WiFi dongle
◦Position it on the top part of the model
◦Place it as far away from metal parts as possible
◦Fasten the USB connector with included cable tie
WiRC module:
◦Use the place of the original receiver, if possible
◦Make sure that cables (Camera, WiFi, Power, Servos, ESC)
can run and connect to the module smoothly
◦Fix WiRC with included double-sided adhesive tape
Before starting installation, disconnect all the
battery, servo, ESC cables and remove the original
receiver – if any.
WiRC is not waterproof. Water and humidity can
cause damage to WiRC, for which we assume no
liability.

1.4 Connecting the cables
1. Connect the camera cable to one of the USB ports on the
WiRC module (You can select any of the two ports)
2. Connect the WiFi dongle to the other USB port
3. Connect the Servo / ESC cables to the WiRC module.
Note the default channel layout as below:
4. Connect the power cable to the WiRC module
5. Secure any loose cables
6. Connect the Power cable to the battery and the ESC
1.5 Powering WiRC
Usually, an RC receiver is powered by the ESC (Electronic Speed
Control) or by a standalone BEC (Battery Eliminator Circuit).
WiRC however has higher power consumption and a minimum
input voltage requirement of 5.5V, that many BECs or ESCs
cannot provide.
Therefore WiRC has to be connected
directly to the battery, by using the
included T-cable.
(see also system diagram on page 3)
WiRC does not have its own on/off
switch.

Instead, it powers on by applying voltage to one of the servo
channels or the POWER_ENABLE pin of the Power Connector.
This ensures that WiRC is always powered on and off together
with the other electrical components of the model.
Please note, that WiRC does not supply power to the servos, the
Ch1-8 connectors only distribute external power coming from
BEC, ESC or additional battery.
If your RC model has no BEC or ESC, then connect WiRC directly
to the Battery_1 to provide the necessary power to WiRC and use
an additional Battery_2 with switched cable for servos.
WiRC has an
operating
voltage of
5.5–16V
Servos

side of the button.
2.4 Settings Menu
For configuration and settings you need to connect to WiRC, start
the application, and select “Settings” icon on the top left corner of
the screen.

11
2.4.1 Basic Settings
You can access the Settings menu with the Settings icon on the
top left corner of the screen. Here you can set:
Transmitter name
The name of the transmitter. By default, this is the name of your
smartphone
Transmitter priority
Defines the priority of your transmitter for multi-driver scenarios.
Changes will effect only new connections.
2.4.2 Channel settings
For each channel being used do following settings:
Channel 1-8

12
Channel name:
Name the channels to remember its function e.g. Steering,
Speed, etc.
Reverse:
Changes the direction of the servo rotation in relation to the
joystick movement.
Test settings button:
Use this button to test Min/Max/Trim settings, when you are
connected to the WiRC. While pressed, the Trim value will be
output for the channel. Once you set Min/Max, their last value will
be output. This allows the quick setup of the three parameters.
Min/Max:
Set the Min/Max value to the desired servo movement or ESC
speed. Max corresponds to the Up or Right position of a joystick
or the maximum speed, while Min corresponds to the Down or
Left position, and the maximum reverse speed.
Trimming:
Sets the center position of a servo, or the idle state of an ESC
Failsafe:
Select the link-loss failsafe action for the channel:
Disable output:
Disable the output of the
channel, so that other failsafe
mechanisms can take over
Last good: WiRC continues to output the last received value

13
Pre-Set: WiRC will output the value you set with the slider
Sensitivity:
Sets the sensitivity type of the
channel. It can be linear to the
control value, or follow an
exponential curve. Negative value of Exponential Factor means
the sensitivity is higher near the center position and lower near
the end position. Positive Exponential Factor means the sensitivity
is lower near the center position and higher near the end
position.
Sensitivity mix / Value mix:
Mixers allow you to set up dependencies between channel output
values. For example, if you want to reduce the steering sensitivity
at higher speeds, you can set up a Sensitivity mix with a
negative factor between the ESC and servo channels. When the
ESC output value is high, the negative sensitivity mix reduces the
channel output changes for the same steering joystick
movement.
Value mixing enables mixing of output values of channels.
Repeat:
Sets the PPM repeat frequency. It can be set for the pair of
channels: 1-2, 3-4, 5-6. Channels 7-8 have a fixed repeat rate of
50Hz.

14
Digital Output 1 - 4
Invert output:
Inverts the state of the digital output, i.e. 0 is output instead of 1
and vice versa
State On range:
Defines the input value at which the digital output is switched on
Between Min-Max range: On
Outside of Min-Max range: Off
2.4.3 Controls
You can assign a control element (joystick, gyroscope or button)
to each channel or digital output.
