1Safety
The Vector is intended to be used exclusively for recreational purposes in model aircraft. Using the Vector for
other purposes is not supported. Further, using the Vector in situations where its use or failure could result in
loss of life, bodily injury or property damage is expressly prohibited.
Eagle Tree Systems, LLC, is not responsible for your use of this product, or for any damages or injuries
you may cause or sustain as a result of its usage.
1.1 Read the Manual!
This manual contains important instructions related to safety. Read the entire manual before proceeding, to
become familiar with the features and operation of the Vector. Failure to correctly configure or operate the
Vector could cause damage to personal property or serious injury!
The latest version of this manual is available in the Product Manuals section of the Support tab on
http://www.eagletreesystems.com.
If, after you read the manual, you have further questions or problems, see the “How to Get Help” section below.
Reading this manual is probably more enjoyable, and will probably take less time, than rebuilding your
model!
1.2 Special Symbols used in the Manual
Warning that could affect safety or result in injury, a crash, property damage or Vector hardware
damage if not heeded.
Under construction. This feature is experimental, incomplete, or under active development.
Information applicable only for fixed wing models
Information applicable only for multirotor models
Helpful Note or Tip
1.3 General Safety Precautions
In addition to other warnings and other precautions in this manual, the following should always be
observed:
The Vector is intended for recreational use only, in model aircraft. Any other use is not supported.
Never connect ESCs or servos to the Vector until you have verified the airframe type is correctly
selected! Doing so can cause multirotor propellers to spin at high speed, or can destroy fixed wing
servos.
Always remove propeller(s) or otherwise disable motor(s) when configuring the Vector!
Always move a safe distance away from the model before starting the motor(s), and never approach the
model with the propeller(s) spinning! Never approach a multirotor when it is armed!
Always wear eye protection when operating models with propellers!

USER GUIDE

RC models and accessories are not toys! The Vector should not be used by children.
You should always use a spotter if your eyes are not on your model. For USA customers, please refer
to the Academy of Model Aeronautics Safety Code at http://www.modelaircraft.org/files/105.PDF and
FPV related code at http://www.modelaircraft.org/files/550.pdf
Always obey the law when flying. Most video transmitters used for FPV flying require an amateur
radio license to operate legally.
If you have never set up or operated an RC model before, you will need help from an experienced
modeler. Local RC clubs are great ways to meet experienced modelers, and receive the required
training. This requirement is especially true for FPV flying, which can be more challenging.
Never operate your model aircraft near or over buildings, power/telephone lines, or other obstacles.
Never operate your model aircraft near or over people or animals! Never operate your model after
consuming drugs or alcohol!
Never operate your model within 5 miles of airports, without permission from the airport!
Never operate the Vector in a situation where it may get wet, such as on a rainy day.
Do not change wiring in your model when any power is applied.

consider upgrading.
2.5.3 Updating your Vector Firmware
Even if you will be configuring the Vector using the stick menus, it’s a good idea to keep your Vector firmware
updated, in case we add a feature or resolve an issue that is relevant to your airframe. Our latest software
always has the latest Vector firmware included with it.
To check to see if you have the latest firmware, first check
what firmware version is installed on your Vector, which is
displayed at the bottom of the Vector boot-up OSD screen.
Or, you can check the version by using the firmware update
utility described below. Then, compare your version
number with the latest Vector firmware version we have
released (listed on the software download page on our
website).
To update the Vector firmware, install the latest software,
connect the Vector to USB, click the “Firmware Update”
button in the software (in the bottom row of buttons), and
follow the instructions.
Make sure that your GPS/Mag is connected to your Vector before updating firmware. The firmware on
the GPS/Mag will also be updated automatically, if needed.
Also, note that if you install new software and it detects that the Vector’s firmware needs an update, it will
automatically run the firmware update utility.
2.6 Getting Notified about Important Vector Updates
Eagle Tree updates the Vector firmware and software periodically to add new features or to address issues that
may arise, and will issue important hardware information bulletins as needed. There are two ways to get
notified about these:
1) Subscribe to the Vector update notification thread on RCGroups. Whenever we update the software or
release a hardware bulletin, we will post a note to this thread, and subscribing to it should result in you
receiving an email. Note that this thread will normally be closed, so only we can post to it, reducing the
number of emails you will receive.
http://www.rcgroups.com/forums/showthread.php?t=2159747
2) Follow us or like us on Facebook™. We will post a note on Facebook indicating that new software or
important hardware information has been posted, and you should see that on your Facebook page.

2.7 Glossary of Terms used in the Manual
Here are definitions for some of the terms used throughout the manual.
FPV –FPV stands for First Person View. If you are not familiar with FPV, there are many websites devoted to
it. Our FPV overview web page at http://www.eagletreesystems.com/OSD has a brief tutorial on FPV, which is
a good place to start.
OSD –OSD stands for On Screen Display. The OSD shows flight information, overlaid on the video camera
image.
RTH –Return to Home. The Vector can optionally return your model to the home point if R/C link is lost.
Software –the term “software” in the manual refers to our Windows PC software application.
Firmware –the firmware is the code that runs on the Vector itself. The latest Vector firmware is included
with the software.
Flight Controller or Stabilizer –the aspect of the Vector that stabilizes your model during flight
Pitch –Lift or descent of the nose and tail of the
model (front to back tilt on multirotors). Normally
controlled by the elevator, or movement of elevons in
same direction.
Roll –Rocking movement of the wings, side to side
(side to side tilt on multirotors). Normally controlled
by ailerons, or movement of elevons in opposite
directions.
Yaw –Turning of the airplane without banking
(rotation on multirotors). Normally controlled by
the rudder.
Axis –an imaginary line drawn horizontally through
your model’s wing (for Pitch), horizontally through your fuselage (for roll), or vertically through the center of
your fuselage (for yaw).
Gain –a setting that controls how hard the stabilizer works to hold the orientation of the model around a
certain axis.
Oscillations –rapid swings of your model around one of its axes, due to a gain setting being too high.
Mode 2 Radio: Transmitters with rudder and throttle on the left stick, and aileron and elevator on the right
stick.
Control Stick –The stick on Mode 2 radios that controls elevator and aileron functions (pitch and roll).
Attitude –The orientation of the model with respect to the horizon.
2D Mode –A mode where the model is brought to a level attitude (level flight and level wings) by the Vector
when the control stick is centered.
3D Mode –A mode where the Vector attempts to hold the model’s present attitude when the control stick is
centered, by moving the model’s control surfaces automatically.
Gyro Mode –A mode where the stabilizer responds similarly to having gyros installed on the control surface
outputs.
Heading –The present direction of travel of the model with respect to North.
Control Surfaces –Your model’s elevator, ailerons (or elevons), flaperons, and/or rudder (if equipped).

USER GUIDE
12
Mode Switch –A two or three position switch on your radio transmitter which you have configured to control
the “Mod” input on the Vector’s Receiver Connection Harness.
Toggle –One fairly rapid movement the Mode Switch between its extents. (UP/DOWN or DOWN/UP)
Configuration Gestures –A series of toggles of the Mode Switch. The number of times you toggle the switch
determines which configuration step is performed.
PSU - Power Supply Unit. This refers to the 5V and 12V switching regulators built into the Vector current
sensor.
Toilet Bowl –When a multirotor is hovering, the condition of orbiting around the desired hover point,
sometimes in an ever increasing diameter, due to compass error or other issues.

3Connecting the Vector
This section describes the Vector’s cabling and
connections, and how to connect the Vector to your
RC receiver, your servos or ESCs, and your FPV video
transmitter and camera.
3.1 Vector Controller Connections
The figure below shows the function of each of the
Vector’s ports, and other Vector information.
3.1.1 Backup Power
If you want the Vector to use a redundant power supply for safety, the middle pin of the RSSI/5V Backup
connection can be used to supply backup power to the Vector. Normally the Vector is powered by 5V from the
Current Sensor/PSU, but the Vector will take power from the backup connection whenever the voltage at this
pin is approximately 0.5V higher than the voltage coming from the Current Sensor/PSU.

USER GUIDE
14
For example, if the backup power is connected to the BEC of your ESC (via your receiver), and that is supplying
5.0V, the Vector will use the PSU power unless the PSU voltage drops below 4.5V. Likewise, if your BEC is
providing 6.0V to the backup power port, the backup power port will always be powering the Vector unless the
BEC output fails.
Note that the backup power input will NOT power your camera or video transmitter. Only the Vector
and accessories connected to the “Bus” port will be powered.
3.2 Vector GPS/Mag, Current Sensor/PSU, and Accessory Connections
Connections to the Current Sensor/PSU (DeansTM version shown), the GPS/Mag, and the optional Pitot Airspeed
sensor, Alerter buzzer/LED*, and InfoPanel telemetry/status/menu display are shown in the figure below.
The “Bus” connectors on the GPS/Mag and other accessories are internally connected together. Wiring
order, or which of the two connectors on each sensor is used, does not matter. In other words, you can plug
into either “Bus” connector, and if you “daisy-chain” the Airspeed with the GPS/Mag, either unit can be at the
head of the chain.
The InfoPanel can be “hot” plugged and unplugged. If you wish to use the InfoPanel either before or
after flying, and don’t wish to permanently mount it on your model. If you plan on doing this, the InfoPanel
should be connected at the end of the chain.
* The high power LEDs and buzzers in the Alerter Buzzer/LCD impose restrictions on the 5V PSU. Do not
exceed 500mA current draw on the 5V PSU tap when using the Alerter, and see section 3.5.2.1 before
using the GoPro AV Harness!
Never connect the GPS/Mag or other accessories to the Vector’s AUDIO connection. Doing so will destroy the
sensor!

3.3 Vector Current Sensor/PSU Power Output
The Vector’s high efficiency and low noise PSU accepts up to 6S voltage input, and provides filtered 5V and up
to 12V output at 1A max per channel*. It's perfect for powering most FPV gear, and can also power your
receiver on multirotors (when NO servos are being powered by the RX!), eliminating the need for an external
BEC.
Never use the PSU to power any servos on your model! The PSU can shut off due to excessive power
draw, causing a crash! Servos MUST be powered by a stand alone BEC, a BEC built into your ESC, or a
separate radio flight pack!
* When the Alerter Buzzer/LCD is used, 5V PSU output draw must be limited to 500mA.
Note that the 12V regulator does NOT boost the voltage, like a SEPIC. However, the Vector's 12V PSU has a
unique Low Voltage Loss feature that drops the regulator’s output by only about 0.5V if you are using a 3S
pack operating below 12.5V. For example, if your 3S pack is at 11.5V, the regulator outputs about 11V. Other
non-boost switching regulators typically drop the output voltage by 1.3V or more.
SEPIC and other voltage boost regulators are generally much less efficient and generate much more UHF band
noise, and in many cases you don’t need one. You never need one if your pack is 4s or above, and all known
cameras and many transmitters will operate well across the 3S pack voltage range. Typically, 1.3GHz
transmitters may provide reduced power output with less than 12V voltage, and 5.8GHz transmitters work fine
at less than 12V. Be sure to check your transmitter manual’s specs to determine this. If your transmitter does
need a boost when operating at the lower end of 3S, a JST equipped boost regulator can easily be connected
into the Vector's video harness (between connections “A” and “E” in the video harness drawing below).
3.4 Current Sensor Maximum Continuous Current, and Load Testing
The current sensor’s continuous current capability depends on the type of connectors/wires you are using, and
other factors.
If your model draws a large amount of current (greater than approximately 60 amps continuous) make sure
you verify that your power system, including the current sensor, can handle your worst case continuous
current load.
In high current applications it is recommended (if you can do so safely) that you run your model in an extended
stationary “bench” test, similar in duration and power usage to your most aggressive modeling, to ensure there
are no problems with any connections, wiring doesn’t get too hot, etc. DO NOT OPERATE YOUR MODEL IF
YOU HAVE PROBLEMS DURING THIS EXTENDED STATIONARY TEST!
It is also recommended that the current sensor be mounted so that airflow is directed through one of the
openings of the sensor.
Never exceed the manufacturer’s continuous current rating for the types of connectors installed on your
current sensor! If the current sensor or wiring becomes too hot during flight due to too much current,
the connectors can fail, or the PSU can shut off, causing a crash!
Make sure that the connector contacts on your current sensor and mating connectors are not damaged or
weakened. A damaged or weakened contact can potentially fold over and short when connected, or cause
intermittent in-flight failures!

3.5 Vector Wiring
The Vector’s wire harnesses are shown below. Note that
a set of replacement wire harnesses is available (p/n VEC-
CAB-SET). Having additional sets make it easier to move
your Vector from model to model.
Video Harness –routes video signals, and provides
power from the Current Sensor/PSU to the Vector, and
optionally to your video transmitter, camera, and
microphone.
Audio Harness –this cable connects to your microphone,
and also to the audio output of your video transmitter.
Receiver Connection Harness –this cable connects
between the Vector and your RC receiver/LRS.
GPS Harness –this cable connects between the Vector and the GPS/Mag.
3.5.1 Vector Video Harness + Connecting your Video Camera and Transmitter
The Vector's innovative video harness makes it easy to connect your 5V or 12V cameras and transmitters
without keeping an electrician on standby. The figure below shows a typical hookup, with a 12V camera, 12V
transmitter, and a microphone.

The first step to wiring your camera and transmitter is to install servo connectors on the wire harnesses that
came with these components, if the wire harnesses don’t have servo connectors already. Servo connectors and
crimpers are available online or at your local hobby store. Either Futaba™ or JR™ style connectors will work.
Also note that FPV shops like
http://www.readymaderc.com
also supply Vector compatible
servo adapter cables for most
cameras and video transmitters.
Refer to the figure at right.
Consult the manuals for your
camera and video transmitter,
identify the signal, power and
ground wires, and install the servo
connectors on these wires.
Make sure the polarity of the servo connector is correct, so that the “S, + and –” pins of the connector
align correctly the “S, + and –” pins of the mating female connector on the video harness!
If you are using a camera with a built-in battery, such as a GoPro™, the power servo lead does not need
to be connected.
Referring to the video harness diagram below, connect the camera’s servo connector to camera connector “F”,
and the video transmitter’s servo connector to transmitter connector “C” on the video harness.
Inside the Vector, the red wire of the camera power connector “D” is internally connected to the red
wire of the camera connector “F”, and the red wire of transmitter power connector “E” is internally connected
to the red wire of transmitter connector “C”. Also, all ground (black) wires are internally connected in the
Vector.

3.5.2 Providing power to your Video Transmitter and Camera
Powering your video equipment is typically very easy with the Vector.
Here are typical wiring strategies, depending on the number of batteries desired, transmitter and camera
voltages, etc.
Video Setup
Wiring Method
Single Battery, 12V
camera, 12V transmitter
Connect both red PSU power taps “A” to camera and transmitter power inputs “D”
and “E”
Single Battery, 5V
camera, 12V transmitter
Connect the white PSU power tap “B” to camera power input “D”. Connect a red
PSU power tap “A” to transmitter power input “E”.
Single Battery, 12V
camera, 5V transmitter
Connect the white PSU power tap “B” to transmitter power input “E”. Connect a
red PSU power tap “A” to camera power input “D”.
Single Battery, 5V
camera, 5V transmitter
Construct or purchase a JST Y cable. Connect the female end of the Y cable to the
white PSU power tap “B”, and connect the two male ends of the Y cable to
transmitter power input “E” and camera power input “D”.
Separate Video
battery(s)
Connect video battery(s) of appropriate voltage(s) to camera power input “D”
and/or transmitter power input “E”. Note that if you want to use one video
battery for both camera and transmitter, a JST Y cable will be needed.
Make sure that you do not make a mistake in the wiring that causes 12V power to be used with a 5V
camera or transmitter! This will likely destroy the camera or transmitter.
Remember that if you use a 3s or lower pack, the 12V power taps will provide a voltage that is about
0.5V less than the present pack voltage. If your video transmitter reduces output power with voltages less
than 12V, and you need maximum range, you will need to insert a “boost” or “SEPIC” regulator between the
power tap “A” and the transmitter power input “E”, or use a separate video battery.
Never exceed the 1 amp current limit for either the 5V tap or the 12V taps. Do not exceed 500mA draw
on the 5V tap if the Alerter is used. The affected voltage regulator may shut off if this is exceeded,
which can cause the Vector to turn off during flight if the 5V regulator is affected, as well as shutting off the
affected video equipment! Never use the taps for powering equipment other than your video equipment!
Normally, only extremely high power video transmitters would exceed 1 amp, but check your video equipment
manual.

3.5.2.1 Plug and Play AV Harnesses for Fatshark and GoPro
Eagle Tree offers optional plug and play AV cables for direct connection with FatShark/IRC style transmitters
with Fatshark cameras, and with GoPro cameras.
Using the GoPro cable to power your camera: the red wire going between the GoPro connector and the
Vector video connector can optionally be used to power your GoPro in flight, from the Vector’s 5V PSU.
If you decide not to use this function and rely on the GoPro’s battery (recommended), disconnect the red wire
from the GoPro connector to the Vector video harness, and cut/cap it.
Before using the wire to power your camera, please read the following:
1) The power function of the GoPro cable is NOT compatible with the Alerter Buzzer/LED, due to
excessive current draw! Do not leave the red wire connected if you use the Alerter!
2) Some GoPro models and firmware versions do not work correctly when recording and powered. The
live video output can be distorted and not be visible, and also there are reports of GoPros locking up
during recording.
3) It is recommended that your GoPro battery is fully charged before flight, whether or not you leave the
red wire connected. This reduces load on your main pack.
If you decide to power your GoPro, it is recommended that you configure your GoPro as it will be in
flight, and do a bench test without motors (with the GoPro recording) lasting the length of a typical flight, to
confirm that the GoPro works correctly.
3.5.3 Vector Audio Harness and Audio Connections
If you do not want to hear Vector voice alerts or the acoustic variometer, it is not necessary to use the audio
harness, so this step can be skipped.
Refer to the figure:
To hear voice alerts or the acoustic variometer from the
Vector, connect the audio harness to the Vector’s Audio
connector, and connect your video transmitter’s audio
in servo connector (described above) to the “Tx Audio”
connector on the audio harness.

To use an external microphone in this configuration, connect the microphone to the audio harness “Microphn”
connector, paying attention to the correct pinout.
Note that the voltage supplied to the red wire of the “Camera/Mic” power input connector “D” on the
video harness will be supplied to the red wire on the “Microphn” audio harness connector.
3.5.4 Vector Receiver Harness
The Receiver Harness is used to connect the Vector to the outputs of your receiver. The pin-out for the
Receiver Harness is shown below.
Do not power your receiver with a voltage higher than 16V.
The Vector does not power your receiver or servos. You will need to power your receiver and servos
as you would in a non-Vector model, such as with a stand-alone BEC, a BEC built into your ESC, or a separate
battery pack.
Whatever power is provided to your receiver will be routed through the Vector to your servos. Whatever
power is provided by an ESC’s BEC will be routed through the Vector to your receiver and servos.
You can alternatively use the 5 volt tap from the PSU (if not being used to power a 5 volt camera or video TX) to
power your receiver on multirotors. Please see section 3.5.6, “Powering your Receiver on Multirotors" for
additional info.
Three types of receiver inputs are supported with the Vector:
Traditional (parallel): each of the relevant harness connections needs to be connected to the appropriate
output port on the receiver. See section 3.5.7 below for information on connecting the receiver harness inputs
to your receiver.
Serial PPM (SPPM) and S.BUS™ (serial modes): only the “Ail” connector of the receiver harness should be
connected to the SPPM or S.BUS™ output of your receiver. Your receiver’s outputs are programmed in the
Vector, as described later.
Note: Connect only the “Ail” wire to your receiver when using a serial mode. Never connect other wires from
the receiver harness to your receiver if you are using a serial mode!
