User Manual for ARRIS FPV250 with SPRacing F3 Flight Controller
(Cleanflight 1.12.00)
1. How to Connect the F3 Flight Controller to the Computer.
1.1. Do not connect the F3 flight controller to the computer at the first step.
1.2. You will need to install the Google Chrome browser to install Cleanflight Software.
1.3. Open the Goggle Chrome browser, search and install the “Cleanflight” in chrome web store.
1.31 After installed the “Cleanflight”, there will be an icon appear.
1.32 Open Cleanflight, you can then download the relevant driver according to the following
indication.
In “Documentation & Support” column, there is detailed instruction file for F3 flight controller
and firmware download address for different versions. Customer can go there to understand
more about F3 flight controller before began to use it.

Firmware Flasher is used to upgrade the firmware.
1.4. Connect the F3 flight controller to computer by USB cable. (The USB cable will be included in
the package). Make sure the drone is on a flat level surface. Cleanflight will automatically connect
to the F3, if it does not, select the Com Port the F3 board is on then click “Connect”.

1.41 This is the interface after it is connected.
Move the F3 flight controller by hand and check whether there is any change in the display. If the
craft is moving in the display then you are connected to the F3 board correctly.
1.42 Go to “Sensors”menu, if the flight controller is in static station, all the lines will be straight;
while if we move the flight controller by hand, those lines will fluctuate up and down. At this time
we can confirm that the flight controller has been successfully connected. (for 10DOF luxurious
version, since there is a built-in barometer, even in static station, fluctuation could also occur). If
the flight controller does not connect successfully, please check the Com Port and or the driver
has been installed correctly.

2. How to Adjust the Parameter in Software.
4.1. Return to “Setup” menu, put the flight controller in horizontal, then click “Calibrate
Accelerometer” button.
It will remind you whether the calibration has finished in upper left corner (displayed in the grey
bar).

2.2. Then choose “Ports” interface. If the receiver of your drone is PWM or PPM, then use the
default setup. Click “Save and Reboot ”Here we recommend pilots use the PPM and SBUS
connection, because the wiring connection is relatively easy. (R6D supports PPM; Walkera
supports PWM and Futaba supports SBUS).
2.3. If SBUS is selected, please open the “Serial RX ”of UART3, after setting, click “Save and
Reboot” according to the following picture:
Do not change any of the settings on URAT1 column, If you change any of the settings this will
disable the com port connection to the computer and Cleanflight software.

The attached connection diagrams of the 3 modes to help you understand.

3. Enter “Configuration” menu.
3.1. First, we need to set the direction of F3 flight controller. F3 can be installed in any direction,
since the F3 is rotated -90 degrees(notice the arrow on the F3 board), then we need to set the
“YAW” axis. For example, we set the “YAW” to “- 90”, click "Save". Return to "Setup" menu, move
the flight controller by hand to check whether the movement direction of the aircraft in the
software is the same as the movement of the real craft. You must click “Save” for any changes
made. If the movement of the aircraft is different with the model in the software, then you need
to readjust the yaw from 0, 90, 180 or 270 and retry.

3.2. Choose the receive mode. Take R9D as an example. It supports PPM mode.
3.3. Set the ”ESC/Motor Features” in "Configuration" menu according to the following picture.
Click the “MOTOR_STOP” icon to be green like picture showed. This means when the craft is
‘Armed”, motors will not spin till you raise the throttle up a little, if the option is turned off the
motors will spin immediately to the set minimum throttle setting.
For“ONESHOT125” icon, if your ESC supports the oneshort125 firmware, then this option needs
to be turned on(green), the flight controller will be more responsive.
The ARRIS Swift ESC supports ONESHOT125.
For “Min Throttle”, here we randomly set a number (1100 for example), this value will be

changed later.
Third option. We can disarm motors no matter where the throttle is, by using the Arm/Disarm
function in the Modes tab.
3.4. Set the “Battery Voltage” in "Configuration" menu.
Please Note:Only if the voltage detection cable is connected to the battery detection input.
The Warning Cell Voltage is adjustable, usually set to 3.5 or 3.6. If the voltage reaches this value,
the buzzer will activate to warn you of low voltage.
3.5. Set the PID. Click "PID Turning" button.
3.6. The "proportional" parameter can be known as sensitivity, the higher this parameter is, much
more stable the drone will be, if too high there will be oscillations. Usually we set the parameter
begin from 0, then increase the number continuously through increasing the same value, till
there is slight oscillation, then reduce the setting. Set the “Integral” and “Derivative” by default,
then set the “RATE”. The “RATE” is how fast and hard the craft responds to stick movement.
Usually we set it this at “0.4”. Following is the PID setting for ARRIS 180 and 210. If you are
professional enough, you can set your own parameter according to the real situation of your
drone, this is just for reference. For beginner, we suggest to set the P value according to the

following picture and then adjust step by step.
Please note: This PID is suitable for professional pilots, which will be a little bit sensitive and agile.
Customers can change this setting according to your own situation.
4. Set the Channel of the Transmitter.
Before doing this, we need to make sure the receiver has been bound with transmitter and the
receiver mode is correctly selected. Connect battery, Please remove ALL PROPS. Move the sticks
on the transmitter randomly, if the strips on the "channel map" change in the software, then it
shows the receiver has been successfully bound.
4.1. Set the direct of “Roll”“Pitch”“Yaw” and “Throttle”
For example:
ROLL channel: move the roll stick to the left, the red line in “Roll” column should move to the left;
PITCH channel: move the pitch stick down, the purple line in “Pitch” column should move to the
