1. Overview

This instruction manual applies to the aircraft kits including the Q250 kit, SF250 components

kit, and SF250 assembled kit (with radio transmitter).

Since the Q250 and SF250 kit are provided in components, you need to mount them yourself.

For different aircrafts, check the respective assembly tutorials below.

For Q250

Visit our website www.sunfounder.com, click VIDEO, scroll down to Aircraft Model and find

Q250. You can see 6 videos there on the page, including a basic introduction one and 5

detailed tutorials. The tutorial videos are marked with numbers in order. Aircraft assembly

requires great carefulness and patience, so please follow the steps in the video closely.

2. Connect the Receiver

The wire connection for the PWM Mode is mentioned in the video, but the wiring differs for

various receivers in different modes, so you need to adapt it to the actual situation. First let's

check the pins of the CC3D flight controller.

CC3D Flight Controller

The pins of CC3D flight controller is as shown below. When wiring, you should be clear about

the pins’ name and connect them correctly, or a short circuit may happen.

SunFou

nder

Connect to the Receiver

The CC3D flight controller supports three modes: PWM, PPM, and SBUS. Thus as long as your

receiver supports one of these modes, it works with this kit. The wiring for three modes is

described below.

For PWM Mode:

Prepare eight wires for a PWM mode receiver, and connect the receiver and the flight

controller as shown below. You can modify the corresponding channel in software

debugging part.

About the Radio Transmitter

Since a radio transmitter will be used in software debugging, let’s first learn something about it now.

For more details, please refer to the transmitter’s user manual.

Talking of radio transmitter control, here a term is involved: "channel", meaning how many

types of movement the copter can make by the radio transmitter control. For example, up

and down can be counted one channel. If the radio transmitter control can only control

the copter to fly up and down, it's called one channel.

For a quadcopter, at least four channels are needed, namely, up-down, right-left, forward-

backward, and clockwise-counterclockwise rotation. The corresponding channels are

throttle (up-down), roll (right-left), pitch (front-back) and yaw (clockwise-counterclockwise

rotation). If you want more functions, more channels are required.

SunFou

nder

Before applying the radio transmitter, you need to know there are two different types of

radio transmitter. They are different in the position of throttle – left (what we provided in this

kit) and right. The throttle controls the motor speed. The higher you push it, the motor rotates

faster, and the quadcopter flies higher, and vice versa. It is quite easy to tell the throttle. Try

to pull the two rocker arms. The one that will not restore to the middle is the throttle rocker.

Radio Transmitter (left hand throttle)

Radio Transmitter (right hand throttle)

See the figure below for the throttle type.

Mode 1 (Throttle left) Mode 2 (Throttle right)

The four rocker channels are Throttle, Rudder, Elevator, and Aileron, which are Throttle, Yaw,

Pitch, and Roll respectively in the software. The mapping relationship is as shown below:

Throttle Throttle

Rudder Yaw

Elevator Pitch

Aileron Roll

Here we take OpenPilot as an example, but you can also use LibrePilot instead. Check the

installation steps below:

Open the GCS installer file downloaded and take these steps:

1. Choose a language from the drop-down list on the first page, then click OK. (You can

cancel installation at any point by clicking Cancel.)

2. The OpenPilot Welcome screen appears. Click Next.

3. Review the conditions of the license agreement and then click I Agree to accept the

terms.

4. You can select which components to install in the Choose Components dialog box. Click

Next to accept the default selections.

5. Click finish to complete the installation

Plug in the CC3D Flight Control

Connect the CC3D flight controller to computer with the Micro USB Cable included, and

you can see the Power LED lights up and stay brighten constantly, while the Status LED blinks.

The driver installation will take some minutes; a reminder of failing to install may pop up as

shown below, and you can just ignore it - the installation result in Device Manager shall

prevail.

Open Device Manager. If you see CopterControl Virtual COM Port (COMxx) (the number

depends on your actual situation), it indicates the flight controller has been recognized by

the computer.

If you see the CopterControl with a yellow exclamation mark！in Other devices:

SunFou

nder

12

There are two possibilities:

1) OpenPilot or LibrePilot GCS is not installed yet;

2) The driver failed to install.

Right-click CopterControl, and click Update Driver Software…

Select Browse my computer for driver software.

SunFou

nder

13

Click Browse to enter the installation path of OpenPilot (or LibrePilot), and select the driver

folder, then click Next.

When the installation is all done, click close to exit. Then you can see the flight controller has

been recognized by the computer.

SunFou

nder

14

Later during the application, sometimes it may happen that the device cannot be

recognized. Don’t worry, just try to replug the USB cable, or reburn the firmware.

Configuring the Wizard of CC3D

Ensure the CC3D flight controller is kept connected to the computer, and double-click to

open the GCS just installed. The TX and RX data at bottom indicates the flight controller’s

connecting status. If they are both in grey, it means the flight controller is not connected.

Just replug to try.

Click Vehicle Setup Wizard and enter the interface of configuring the wizard as shown

below:

SunFou

nder

15

On the interface of configuring the wizard, there is a red mark reminding you to disassemble

the propeller blades before configuring the wizard in case of any accidents. Then click Next

to enter the interface of firmware upgrading.

It will prompt you that the version of the firmware should be consistent with that of the GCS.

For the first time of configuring, you're suggested to upgrade the firmware. Take the

following steps:

Unplug the battery and USB cable from OpenPilot to ensure the CC3D flight control board

is powered down and no LED is on.

Click Upgrade

Plug the USB cable when the bar starts running. Then the GCS will automatically write the

latest firmware onto the board.

SunFou

nder

16

After writing is done, then click Next to configure the receiver of the remote-control system.

Select the corresponding mode according to your receiver’s wiring. Here we take PWM

mode as an example.

Click Next. Choose the type of vehicle the OpenPilot controller board is going to be used

with. Choose Multirotor among the four types of vehicles - Multirotor, Helicopter, Fixed wing

and Surface.

SunFou

nder

17

Then, choose the multirotor type. There are several choices provided on the drop-down list

of the multirotor type. Choose Quadcopter X.

Click Next. Choose Rapid ESC.

SunFou

nder

18

Now you can see all the settings you just completed displayed on the interface.

Click Next to go to the interface of calibrating the sensor. Be careful to ensure that the

vehicle is really level before calibration to avoid any error.

SunFou

nder

19

For hardware configuration, if you don't remember the options or are not sure about the

settings, just leave the default option selected.

Calibrating the Motor Output

Enter the interface of output calibration of the motor. Pay attention to disassemble the

propellers before switching on power.

Follow the instructions on the page to operate: DO NOT connect the battery right now; tick

all the precautions first (reality should also meet the conditions), click Start and connect the

battery to the aircraft, and then click Stop after hearing a beep from the ESC. Finally,

disconnect the battery, and then click Next.

SunFou

nder

20

Click Next.

SunFou

nder

21

The output calibration means setting the neutral rate for the motor. Follow the steps below:

Step 1: Connect the battery to the aircraft.

Step 2: Press the Start button below and slide the slider to the right until the motor starts to

spin.

Step 3: Click Stop. When the motor stops, press Start again to see whether the motor can

start itself. Slide the sliders to the left or right to set the critical point of the motor to spin.

Step 4: Please pay attention to the rotation direction of the motor. Ensure the motors are

spinning in the correct direction as shown in the diagram. Otherwise, swap any two wires of

a motor to change the direction.

Since the output calibration of the Motor 2, 3 and 4 is the same as the Motor 1, just set their

neutral rate in the same way as setting the Motor 1.

Note: Pay attention NOT to make the motor spin too slowly because it will give out much

heat at the critical point, which may damage the motor.

SunFou

nder

22

After setting, select the type of your air frame. For a Q250 quadcopter, choose Current

Tuning. And for SF250, please choose QAV250. Then click Next.

Click Save to save the configuration directly to your OpenPilot controller.

SunFou

nder

23

After saving, there will be an interface of rebooting your controller. Just wait for a while.

SunFou

nder

24

Configuring the Radio Transmitter

During the configuration of the radio transmitter, the default option is that the GCS of the

CC3D disables the unlocking of the throttle. You'd better check whether the throttle is

locked before configuration to avoid any damage during the configuration caused by

having forgot to unload the battery. Click Transmitter Setup Wizard to enter the interface of

configuring the radio transmitter.

You can also click Finish and choose another way to configure the radio transmitter like

clicking Configuration->Input->Start Transmitter Setup Wizard as shown below. SunFou

nder

25

Pay attention to the points below before configuration:

1) Keep the receiver correctly connected to the flight controller which is powered by a

battery. If not, follow steps in 2. Connect the receiver to connect.

2) Switch on the radio transmitter; make sure your transmitter works well with the receiver,

and they can be paired.

After entering the interface of configuring the radio transmitter, follow the prompt on the

screen to pull the rockers. You can cancel or return to the last step at any time during the

configuration. SunFou

nder

26

Next, choose the type of transmitter of the radio transmitter between Acro and Multicopter.

Acro is suitable for fixed wing aircraft and quadcopter. Therefore, here choose Acro.

Next, select the transmitter mode of the radio transmitter. Here are two options: throttle-left

mode and throttle-right mode. The default one is the throttle-left mode namely Mode 2 as

below: Throttle and Rudder on the left, Elevator and Aileron on the right.

SunFou

nder

27

Click Next, follow the prompts on the screen to calibrate the throttle, aileron, elevator, and

rudder respectively.

Notes:

Firstly: When you move the throttle stick for the first time, if it is moved all the time even when

you move other channel sticks, you should follow these steps to check.

1) Check whether the receiver is correctly connected to the CC3D board. Pay attention

to the wire order and not to inversely connect the wires.

2) Check whether the power supply of the CC3D is turned on. Only the USB port for

CC3D is not enough to power the receiver.

3) Check whether the receiver and the transmitter are matched successfully. Press and

hold the button on the receiver until the LED onside blinks, and then the LED will

brighten constantly, indicating the receiver is matched successfully.

4) Check the receiver’s mode. You need to be aware of the color of the LED on the

receiver for each mode. Press the button twice quickly to shift modes.

If after you move one stick of Throttle, Pitch, Roll, and Yaw, the stick on OpenPilot still moves,

it means the corresponding channel has not been configured well. Then click Back, and

repeat the previous steps to check.

SunFou

nder

28

Then, calibrate the flight mode. A 3-way auxiliary channel would be better to set. Note

down the aux channel for flight mode setting, since we will use it later.

Configure Accessory 0, Accessory 1 and Accessory 2. If you don’t want to do that, just click

Next/Skip.

SunFou

nder

29

After all the configuration, keep all the channel switched at neutral. Click Next.

Please move all controls to their maximum on both directions to check whether all channels

have been configured well. You should see the stick in OpenPilot moves as the real stick

does. If not, please click Back to configure that channel again.

SunFou

nder

30

Based on the instructions, pull the throttle, aileron, elevator, or rudder or toggle the mode

switch to check whether it moves in the same direction as the stick actually does.

For example, when you move the Throttle stick from lowest to highest on the transmitter, if

the throttle stick on the OpenPilot also moves in the same way, it’s OK; but if it move from

highest to lowest, it's got reversed. Then just tick the Throttle in the software and there is no

need to configure it on the radio transmitter.

SunFou

nder

31

Until now, all the configuration of the channels is completed. Click Save and then enter the

configuration of unlocking the radio transmitter.

During configuration of the radio transmitter, by default the throttle is locked. You can

define the method to unlock it in the way you like. Next, set the time of receiving no signal

to automatically lock the throttle. 30s is set by default. Usually, we unlock the throttle through

Throttle off (to the lowest) and Yaw Right.

Finally, Click Save.

Modifying the RX Input Parameters

Click RC Input, and under the tab you will see the parameters for all channels: Type, Number,

Min and Max values, and Neutral etc. Sun

Found

er

32

Some parameters are not reasonably set by default, which may cause failure in unlocking

the aircraft, thus we should modify these parameters prior to flying.

PWM Mode

Click Output on the menu column at the left side. Neutral is the critical point of the motor to

spin that you configured previously. So, we can know the highest critical point of the four

motors is 1088.

Click Input, and set the Min, Neutral and Max values for all channels.

Min: the minimum value of the channel.

SunFou

nder

33

Neutral: the threshold value of the channel. The Neutral for the throttle should be set

greater than that for four motors (1088), and about 50 greater than the Min value, in case

the aircraft takes off when we just slightly pull the throttle; and it leaves enough throttle

ascending space, which would be easier to operate for entry-level hobbyists. Set all

others Neutral values to 1500 (median for Min and Max).

Max: the maximum value of the channel.

Move the channel sticks. If the channel value slider is toggled reversely, just tick Reversed.

For instance, when you move the Pitch stick from bottom to top, if the channel value slider

is toggled from right to left at the same time, it indicates it is reversed. Thus you should tick

the box Reversed after Pitch. Then click Save after modifying.

Check the Flight Mode

Click Flight Switch Mode. There are three flight modes usually:

1) Stabilized 1: Self-stabilization. In this mode, you can only control the throttle to fly the

aircraft. This mode is suitable for beginners.

2) Stabilized 2: Semi-self-stabilization. In this mode, you can control the channel of YAW

and Thrust to adjust horizontal direction and throttle.

3) Stabilized 3: Manual. In this mode, the Roll, Pitch, Yaw, and Thrust channel can all be

controlled, which may be not so easy to operate.

SunFou

nder

36

Move the aux channel for flight mode setting, and you can see the Slider is toggled to the

corresponding position (Pos. 1, Pos. 2, Pos. 3…). For beginners, DO select Pos. 1. You can try

Pos. 2 or higher level when you've mastered the basic control and can handle higher ones.

Note: The figure below is to show you that you can move the aux channel to select the flight

mode, which does NOT mean to select Pos. 2. For beginners, please select Pos. 1.

Click Save.

Calibrating the Aircraft

Actually we have configured the aircraft previously and you can skip this step. But if the

aircraft keeps tilting to one side during the flight, you can take these instructions.

SunFou

nder

37

Click FlightData, and check whether the horizontal line is in parallel with the yellow line or

not. If yes, the calibration is ok; otherwise, follow the instructions below to operate.

Place the aircraft on a leveled surface, click Altitude, then Level to calibrate. When the

progress bar goes to 100%, click Save.

SunFou

nder

38

Click FlightData again, and then you can see parallel lines now.

So you've finished the debugging. Now, let’s mount the propellers, and unlock the aircraft

to check how it flies well.

Note: If an aircraft bumping happens, the setting parameters will change, thus you need to

follow 3. CC3D Software Debugging to configure again.

Setting Parameters Manually

If the aircraft cannot be unlocked and controlled after you take the steps in Configuring the

Radio Transmitter, you can set the parameters manually. Or just skip the settings wizards,

and set them manually.

PWM Mode

Step 1: Ensure the receiver has been toggled to the PWM mode and connected correctly,

and power on the aircraft and radio transmitter with a battery.

Step 2: Open Openpilot, click Input at left side, and then select PWM for all channels under

Type, and set Chan 1-Chan 5 under Number correspondingly. Throttle, Roll, Pitch, and Yaw

are main channels, while FlightMode is an aux channel to set the flight mode. To realize

basic flight needs, you only need to set these 5 channels. Then click Save.

SunFou

nder

39

Step 3: Move the Throttle stick to check the channel value status on the OpenPilot.

If the Pitch changes when you move the Throttle stick, just exchange the channel of Pitch

and Throttle on the interface, then click Save. Now Throttle is Chan3, while Pitch is Chan1.

Step 4: Move the Elevator stick.

If the Roll changes when you move the Pitch stick, similarly just exchange the two channels,

then click Save. Now Roll is Chan1, while Pitch is Chan2.

Step 5: Move the Aileron stick.

If the Roll channel value changes, no need to modify its channel. But if the Yaw changes

when you move the Roll stick, just exchange the channel Chan4 and Chan5.

Step 6: Move the Rudder stick.

Then you may see Yaw channel value changes, no need to modify then. Otherwise swap

the channel values with another channel.

Step 7: Since only CH2 to CH6 are connected of the receiver, you can set FlightMode to

Chan5 first, and move all the aux channels to see which the slider is toggled. Then that one

is Chan5. Note down the position of the aux channel to set the aircraft flight mode later.

Save the setting.

Step 8: Check four motors’ Neutral values.

Step 9: Click Input, and set the Min, Neutral and Max values for all channels.












PPM Mode

Step 1: Ensure the receiver has been toggled to the PPM mode and the receiver wiring has

been connected correctly, power on the aircraft and radio transmitter with a battery.

Step 2: Open OpenPilot, and click Input at left side, then select PPM for all channels under

Type, and set Chan1 –Chan5 under Number correspondingly (Throttle, Roll, Pitch, and Yaw

If the Pitch changes when you move the Throttle channel stick, just exchange the channel

of Pitch and Throttle, then click Save. Now Throttle is Chan3, while Pitch is Chan1.

Step 4: Move the Elevator channel stick.

If the Roll changes when you move the Pitch channel stick, just exchange the channel of

Roll and Pitch, then click Save. Now Roll is Chan1, while Pitch is Chan2.

SunFou

nder

43

Step 5: Move the Aileron channel stick.

If the Roll channel value changes, no need to modify its channel. If the Yaw changes

when you move the Roll stick, just exchange the channel Chan4 and Chan5.

Step 6: Move the Rudder channel stick.

Then you may see Yaw channel value changes, no need to modify then.

Step 7: Since we only connect from CH2 to CH6 in receiver wiring part, you can set

FlightMode to Chan5, and move the aux channel to see whether the slider is toggled or not.

If yes, the corresponding one is Chan5. Remember the aux channel for the aircraft flight

mode setting.

Save the setting.

Step 8: Check four motors’ threshold values.

Click Output on the menu column at the left side. Neutral is the critical point of the motor

to spin that you configured previously. So, we can know the highest critical point of the

four motors is 1089. SunFou

SBUS Mode

Step 1: Ensure the receiver has been toggled to the SBUS mode and the receiver wiring

has been connected correctly, power on the aircraft and radio transmitter with a battery.

Step 2: Open Openpilot, and click Input at left side, then select SBUS for all channels under

Type, and set Chan1 –Chan5 under Number correspondingly (Throttle, Roll, Pitch, and Yaw

are main channel, while FlightMode are aux channel to set the flight mode. To realize basic

Step 5: Move the Aileron channel stick.

If the Roll channel value changes, no need to modify its channel. If the Yaw changes when

you move the Roll stick, just exchange the channel Chan4 and Chan5.

Step 6: Move the Rudder channel stick.

Then you may see Yaw channel value changes, no need to modify then.

Step 7: Since we only connect from CH2 to CH6 in receiver wiring part, you can set

FlightMode to Chan5, and move the aux channel to see whether the slider is toggled or not.

If yes, the corresponding one is Chan5. Remember the aux channel for the aircraft flight

mode setting.

Save the setting.

Step 8: Set the Min value of all channel to 200, Max to 1800. Then the Neutral of Throttle to

400, others to 1000. Then click Save.

The Neutral value of Throttle is the threshold of motor to start spinning, thus we set it to
