2 Remote Controller APP
The MK15 setting parameters are set through the built-in Tuning APP.
2.1 Channel setting
Through the channel setting function, the user can
set the servo stroke, neutral point, servo reverse
and channel mapping of each channel of the remote
control.
Servo stroke
The default range of stroke is -100 to 100. Select the target channel and click to
output the corresponding value to successfully change the servo stroke. Note: -100
means the actual PWM is 1050us, 0 means the actual PWM is 1500us, 100 means the

actual PWM is 1950us.
Neutral point adjustment

Servo reverse
Select the target channel and click the corresponding servo forward and reverse switch
to successfully set the servo forward and reverse.
Channel mapping
The user can freely define the control switch of
each channel from the default joystick, dial and
buttons.
Setting steps: Select the target channel, click
the channel mapping button, the switch list will pop
up, and select the required switch.
2.2
Data Link Setting
Through the data link setting function, the user can select the corresponding type or
set a specific serial port baud rate.
Connection type
The optional data output mode of the remote controller is A-USB or Bluetooth output.
Flight controller type
Select the flight controller you want to use in the flight controller list. Currently
supported flight controllers are: Jiyi, Boying,and open source PIX Hawk flight
controllers.

Baud rate selection
If you are connected to other devices, you can change the flight controller to
custom and manually select the corresponding baud rate to connect.
2.3 System Setting
Adjust the system settings of the remote controller, such as remote control
frequency pairing, changing the language, changing the throttle joystick etc.
Pairing
Please follow the diagram below for frequency matching.

user manual

1. Click "Start pairing" in the APP, the LED status light will flash red light, and the
APP will remind you "paring".
2.Click the receiver pairing button for 2 seconds, the red LED will flash quickly, and
the paring will be successful.
3. After the pairing is successful, the remote controller and the air unit indicator
lights are both green.
Joystick type
Switch the type of joystick, the available types are Mode I, Mode II and custom.
3.4 Fail-safe Protection
Fail-safe function: when the remote controller loses connection with the receiver,
the receiver continues to maintain the output of the channel value you set, which has
reduced the cost of crashing.
If the flight device you are using is equipped with a flight controller and
communicates via S.bus, then you do not need to set the fail-safe protection on the
remote control (except for special requirements of the flight controller, you need to
maintain a value through a certain channel to trigger entry to fail-safe protection s
when it is out of control) , you can set the corresponding protective measures in the
flight control app. There is an out of control bit in the S.bus communication
protocol to tell the flight controller what is out of control. The switch on the left
is the channel of the remote controller. If you need a channel to output a specific
value, click the "Hold" of the corresponding channel to enter "Custom", select the
‘stroke’ and enter the stroke value you need.

Solutions for fail connection
1. First make sure whether the data link wire is connected with the flight controller.
Please check whether the wiring sequence is correct,the flight controller and the air
unit TX and RX are cross-connected. Enter the remote control APP to view the link
information. The flight controller and the air unit are connected normally, and the
downlink value will be greater than 0. When the value is 0, please check the connection
wire.
2. Select connection in the APP but without data, open remote control APP - data link
settings to check whether the connection mode is set correctly, the flight control model
or baud rate setting is correct.
