About the Kit
The Q250/SF250 quadcopter is tailored for the hobbyists for FPV flying. It runs the OpenPilot
firmware of the flight controller and the electronic speed controller. This kit is designed to
meet the hobbyists’higher requirement of flying the aircraft, featuring stability, flexibility and
agility. You can realize a stable flight in a small space or a rapid 3D flight based on your own
configuration and parameter setting.
In this book, we will show you how to configure the wizard of CC3D. In addition, we have
also provided the videos about how to assemble and fly the Q250 and SF250 quadcopters
for you. You can check them under VIDEO on our website.

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.

For SF250
On our website, go to VIDEO -> Aircraft Model -> SF250. You can see 6 videos including a
basic introduction one and detailed tutorials which are marked with numbers in order.
Aircraft assembly is a task that requires carefulness and patience, so please follow the steps
in the video for operation.

For SF250 Assembled Kit (with Radio Transmitter)
For the SF250 assembled kit, most of the components have been assembled except the
propellers and the battery before arriving at your doorstep. Please finish the assembly by
following the tutorial in www.sunfounder.com -> WIKI -> Drones/Model Aircrafts->CC3D ->
SunFounder 250+Radiolink T8FB Remote Controller(Assembled).
The receiver included is a PWM mode one with firmware burnt. If the firmware is missing due
to an aircraft collision or some other reasons, you need to reburn it; please refer to 3. CC3D
Software Debugging.

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.

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.

For PPM mode, since GND, PWR and CH1 are connected together, we need to connect
the 3pin cable to other position, and then connect CH6 to PPM(CH2).

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.

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:
