1 Introduction

The Trimble ZX5

The Trimble ZX5 is an unmanned aerial vehicle (UAV). An unmanned aerial vehicle is a generic term,
and refers to an aircraft that is operated remotely. The ZX5 is a radio controlled, electric powered
aircraft capable of vertical starts and landings. Using electronic sensors and an integrated GPS
receiver, it is self-stabilising in every direction. The ZX5 is able to fly to pre-set waypoints by itself
and also hold its position under windy conditions.

The camera takes aerial images over the defined area. During the flight, the pictures are acquired at
a specified height, along parallel lines with specified overlap between the image exposures. At the
same time, position information of the pictures is recorded for further processing in image
processing software such as Trimble Business Center software.

The high-performance control unit in the ZX5 provides high accuracy. The ZX5 is controlled by
remote control. For extra control, it is possible for the ZX5 and the camera to be controlled
independently using two different control units. This allows the pilot to concentrate on flying while
the camera operator takes care of the ideal camera view to obtain the best pictures.

To assist with repeated air activity the ZX5 is able to learn waypoints and fly them semi­automatically.

The ZX5 is shipped with an optional Inspection Module, which contains the video receiver to allow a
live video feed during flight.

ZX5 system components

The ZX5 aerial imaging system comprises the following components:

l ZX5 UAV

l Camera gimbal, mounted below the UAV

l Ground control station (GCS) for pilot, with or without a video receiver

or

1 Introduction

Propellers

The folding propellers are pre-installed on the ZX5.

There are two different rotation directions for the propellers: clockwise and counter-clockwise. Each
propeller must be attached to the appropriate motor so that the ZX5 can fly safely.

WARNING – Always ensure propellers are fitted to the correct motor. If one or more propellers are

fitted to a motor that rotates in the opposite direction to the propeller, the ZX5 cannot fly correctly
causing loss of control. Loss of control of the ZX5 may lead to a crash, resulting in equipment damage,
property damage, or personal injury.

The propellers are very light, but also fragile in case of a hard landing. Each folding propeller is a unit
made of two blades and a center piece. The propeller unit is dynamically balanced during
manufacture to operate at 8000 rpm. The propellers must be properly balanced to avoid vibrations
during flight. Make sure the propellers are kept clean. For more information, see Check the

propellers, page 22.

Avoid contact with other objects during transportation and flight. Fold the propellers before
storing the ZX5 in the flight case. For more information, see Transportation, page 20.

WARNING – Never fly with a damaged propeller. Always replace a damaged propeller before the next

flight. Always replace the full propeller, not just a single blade as the two blades are dynamically
balanced. Exchanging only one blade will create vibration. A damaged propeller can cause loss of
control of the ZX5 which may lead to a crash, resulting in equipment damage, property damage, or
personal injury.

CAUTION – Make sure the propellers are properly balanced before flight to avoid unnecessary

vibration. Vibration can cause blurred and out of focus images or affect the flight characteristics of the
ZX5, causing damage to the ZX5 or loss of control.

For maintenance of the propellers, refer to the Trimble ZX5 Maintenance Guide.

Battery pack

The ZX5 is operated by two high-power lithium polymer batteries connected in parallel. To get the
best performance and lifetime, the two batteries should always be used together. The pair of
batteries is only as good as the bad battery.

Trimble ZX5 User Guide 11

1 Introduction

CAUTION –Do not separate the battery pack. Always use the complete battery pack for the lifetime of

the poorest battery. Attempting to separate the battery pack will damage the batteries.

Lithium polymer batteries are characterized by their low weight, high capacity and high power
output.

Correct handling of the batteries is essential to delay the inevitable aging of the battery cells. With
time and use the voltage level of the cell is reduced and the inner resistance is increased. The
batteries deliver less current.

To delay the aging process:

l Use the batteries regularly (approximately once per month).

l If the ground control station warns "Low battery" during flight, end the flight, let the battery

cool (wait 30-45 minutes), and then recharge it. Lithium polymer batteries have no memory
effect, and fully discharging them will only shorten their life.

Always recharge the battery pack before use. For more information, see Charging the ZX5 battery

pack, page 24.

Storing the battery pack

WARNING – LiPo batteries should never be stored at full charge for more than a few hours at most.

Note – The charger can only charge a battery; it cannot discharge a battery.

Stored batteries should be recharged every three months.
For optimal battery life, store the ZX5 batteries in a cool, dry area (below 15–20 °C / 59–68 °F) that is

subject to little temperature change.
During flight the temperature of the battery is regulated due to the flow of current. When not in

flight, elevated temperatures can result in reduced battery service life. Do not place batteries near
heating equipment, nor expose to direct sunlight for long periods. Do not store or transport
batteries above 60 °C (140 °F) or below 10 °C (50 °F). Extreme temperatures will result in the battery
venting flammable liquid and gases. Do not store the battery inside a vehicle. Temperatures inside
a vehicle can rapidly exceed the recommended maximum storage temperature.

Batteries should be separated from other materials and stored in a noncombustible, well
ventilated, sprinkler-protected structure with sufficient clearance between walls and battery stacks.

CAUTION –To avoid damaging the electronics, avoid contact with the electronic devices and

conducting paths on the board.

Data connector

The data cable port is for connecting the data cable to upload
missions created using the GroundStation software.

Before connecting to the ZX5 for the first time, make sure the
computer running the GroundStation software has an
Internet connection so that the appropriate drivers can be
downloaded automatically. For more information, refer to
the GroundStation Software for the Trimble ZX5 User Guide.

Note – Installation make take some time. If you experience
issues installing the drivers, go to

www.ftdichip.com/Drivers/VCP.htm.

Before uploading the mission, connect the data cable to the indicated port below the dome and to
the USB port of the computer that has GroundStation installed.

During flight, the ZX5 records the GPS coordinates for each photo location. Use the data cable to
download the GPS coordinates after the flight, so that the images can be synchronized with the
correct coordinates.

Remote control receiver with antenna

The remote control receiver works in a range of 2.4 GHz, using a dipole-antenna to keep
interference as low as possible. The yellow antennas are secured by a flexible hose.

CAUTION –Take care never to bend the antennas. The antennas should be aligned in a straight line

and at a 90° degree angle to each other. Damaged antennas may reduce the range of the remote
control and cause loss of control of the ZX5.

Trimble ZX5 User Guide 14

1 Introduction

Video transmitter with antenna

This is available with the Inspection Module only.
The video transmitter is installed into the camera gimbal. It works in a frequency range of 5.8 GHz.

It is connected with the video antenna shown. The antenna can be adjusted by turning it at the
plug. Find the ideal position for reception by trying. This will vary, depending on the external
conditions and the camera in use (shadowing effects).

Note – Avoid obstacles or barriers between the ZX5 and the video receiver as they can cause
image interference.

Flight recorder

A micro SD card slot is located on the flight control panel beneath the dome. The flight recorder
uses the micro SD card to memorize all system and sensor data during the flight. If you should have
problems with the ZX5 you can import the flight data on the SD card to your computer and then
send it to your Trimble distributor. To get to the board you must remove the dome. Press onto the
card to release it.

The ZX5 can be started only when the micro SD card provided with your system is inserted. If you
lose or damage your card, contact your Trimble distributor.

1 Introduction

CAUTION –The micro SD card contains data files that can be read only with the appropriate software.

Damage to the data on the micro SD card can render the ZX5 and the micro SD card unusable. To
avoid damaging the data:
– Do not reformat the micro SD card.
– Do not copy data from the micro SD card.
– In case of a crash, do not power on the ZX5 afterward as this can cause overwriting of the latest flight
data and the reason for the problem cannot be analyzed.

Camera gimbal

The camera gimbal holds the camera. It is attached to the ZX5 frame below the dome. The camera
gimbal provides a straight and stable picture even if the ZX5 flies askew to move or to travel against
the wind.

The roll and yaw axis are controlled by brushless motors and their own stabilising unit. The camera
can be adjusted manually to define the needed pitch to focus the desired object.

The gimbal is powered with its own power switch, located at the side of the gimbal. Beside the
power switch there is a small push button for calibration. For more information, refer to the

4. If you have not yet charged both batteries, connect the second battery and charge it using
steps 4 through 6 in the section "Connecting the charger" above.

Inserting the battery pack into the ZX5

WARNING – Always fully charge the batteries before each flight. Only insert fully charged batteries

into the ZX5. Using partially charged batteries will significantly reduce the flight time.

Note – In low outdoor temperatures (less than 10°C / 50°F) the battery capacity reduces itself
down to about 50 %. When using the ZX5 in such temperatures, keep the ZX5 and the batteries in
a warm environment for as long as possible before the flight.

1. Insert the battery pack into the battery cavity above the camera gimbal at the rear of the
ZX5and then tighten the Velcro straps around it.

2. Connect the main power connectors of the batteries to the rover.

CAUTION –Do not separate the battery pack. Always use the complete battery pack for the lifetime of

the poorest battery. Attempting to separate the battery pack will damage the batteries.

Storing the battery

WARNING – LiPo batteries should never be stored at full charge for more than a few hours.

Note – The charger can only charge a battery; it cannot discharge a battery. Stored batteries
should be recharged every three months.

Battery storage recommendations

Store the ZX5 batteries in a cool, dry area (below 15–20°C/59–68°F) that is subject to little
temperature change. Elevated temperatures can result in reduced battery service life.

Do not place batteries near heating equipment, nor expose to direct sunlight for long periods.

Trimble ZX5 User Guide 29

2 Preparing Equipment

Do not store batteries above 60°C (140°F) or below 10°C (50°F). Battery exposure to temperatures
in excess of 130°C (266°F) will result in the battery venting flammable liquid and gases.

Batteries should be separated from other materials and stored in a noncombustible, well
ventilated, sprinkler-protected structure with sufficient clearance between walls and battery stacks.

Pre-flight acoustical signals

A signal transmitter located on the frame of the ZX5 provides audible signals to report different
conditions:

In addition, the motors buzz after powering up the system.
Other signals could also indicate malfunction. If you hear unusual signals, do not perform any

further flights. Check the MX menu for the latest error message and contact Trimble for more
information.

Note – If there is an acoustic signal for low battery voltage during the flight, you cannot start the
motors again after landing until you have disconnected the battery.

Voice announcements from the remote control unit indicate status information during flight. For
more information, see Remote control in-flight announcements, page 45.

user documentation for the camera.

Note – Make sure you charge both camera batteries before leaving the office for a flight. Trimble
recommends always having a spare, fully-charged battery on hand.

Trimble ZX5 User Guide 30

2 Preparing Equipment

Configuring the camera settings

Refer to the documentation provided with the camera for camera operation instructions. However,
to obtain good aerial images using the Olympus E-PL7 camera, Trimble recommends changing the
camera settings to the following:

1. Set the Mode dial to M (manual mode).

2. Press the Menu button, select the Setup menu and do the following:

a. Set the correct date and time (Trimble recommends using UTC format).

b. Set Rec View to Off.

c. Set Wi-Fi to Off.

d. Make sure Menu Display is set to On, so that you can view custom menus.

3. Navigate to the Custom menu and do the following:

a. Select AF/MF and then set MF Assist / Magnify to Off and Reset Lens to On. This resets

the lens to focus on infinity each time the camera is turned on.

b.

Select and then set the ISO-Auto Set / High Limit to 1600.

c.

Select and then set the Sleep option to Off.

4. If you do not want to manually have to press the shutter switch on the remote control unit to
capture photographs, you can set photos to be captured at regular intervals. To do this,
navigate to Shooting menu 2 and select Time Lapse Settings.

You can set an interval of photos, for example 30 pictures every 2 seconds. You can trigger the
interval with the shutter on the remote control. The interval can be restarted using the remote
control shutter switch as soon as the previous interval is finished or if the number of photos
which are set for the interval is high enough, then you will need to trigger the interval using the
shutter switch only once per flight.

5. Exit the Menu screens to return to Shooting mode. Press the OK button to view the
information display and use the control panel to set the following:

a. Set the Image stabilizer option to Off.

b. Set the Image quality option to LF.

c. Set the Flash mode to Fill-in flash.

d. Set the Brightness (metering) to ESP.

e. Set the Focus mode to MF (manual).

Note – Setting focus to manual and using a large depth of field gives better results than
using auto focus. Resetting the lens to focus on infinity (step 3a above) and using the
recommended ISOsettings (below) gives a large depth of field.

f. Set the ISO settings to a minimum shutter speed of 1/500 with an f-stop value at 5.6

(minimum 4.0).

g. Set the Face priority mode to Off.

Flight functions

The ZX5 comes with different flight functions. It is possible to fly it using full manual control or fully
automatically.

Depending on the remote control unit you are using, different flight functions are available:

l Standard flight functions (DC-16 and DS-14 remote control)

l Flight modes for the DC-16 remote control

Note – Some GPS functions refer to the "starting point". The starting point is usually the takeoff
position. However, if you start the ZX5 and take off before it has time to identify the GPS position,
then the starting position is the first-fix position, which is the point during the flight where the
where the ZX5 can first identify its GPS position.

Standard flight functions (DC-16 and DS-14 remote control)

To operate the ZX5, use the following flight functions on the remote control unit:

Auto start

Automatic start function to facilitate take off.

Requirement: The ZX5 must be on the ground with the motors idling.
Activation: Move the Launch/Landing or Start/Landing switch to the Launch or Start position.
Performance: The ZX5 starts and ascends approximately 2m (6.5ft).

Auto landing

Automatic landing function to facilitate landing.
Requirement: The ZX5 is flying. If the ZX5 is over 10m (33ft) high it descends faster; below 10m

(33ft) the descent is slower.

CAUTION –Only activate Auto landing when the ZX5 is flying with the camera fitted, as flying without

the camera installed changes the center of gravity of the ZX5. Activation of Auto landing without the
camera installed may lead to a crash.

CAUTION –On hilly ground the chosen landing place may be 10 m higher than the starting position. In

this situation the ZX5 may descend too fast and touch ground with too much speed, which can cause
damage. If you think the landing place may be higher than the starting position, land manually.

WARNING –Always pay close attention to the ZX5 when Auto landing is activated, in case you need to

manually intervene.

Activation: Move the Launch/Landing or Start/Landing switch to the Landing position.

Trimble ZX5 User Guide 36

3 Operating the ZX5 Using the R emote Control

Performance: The ZX5 lands automatically.
The motors reduce speed to idle and may appear to have stopped. However, the ZX5 is still turned

on. To avoid injury, you should immediately manually power off the ZX5 by pulling the throttle
stick completely back while simultaneously pulling the motor switch up to move it and then moving
the motor switch down to the motor stop position.

Note – At the moment of touchdown, there should be no sideways movement otherwise the ZX5
can overturn. To eliminate this, manually keep the ZX5 in position to compensate for inaccuracies
in the GPSposition.

WARNING – For safety reasons, after landing the motor speed can increase again after 2seconds

under certain circumstances. To avoid incremental movement caused by inaccuracies in the
GPSposition, immediately shut down the ZX5 motors completely, even if you intend to restart the ZX5.
To do this, pull the throttle stick on the remote control all the way down and move the motor switch to
the Off position. Attempting to restart the ZX5 when the motors are idling can cause loss of control of
the ZX5 and lead to a crash directly after take-off.

Cancellation: To cancel landing, slightly move the left stick.

Go Ahead

Automatic alignment function.
Use this function if the pilot does not remember or cannot see the direction the ZX5 is aligned. The

Go Ahead function turns the ZX5 once only so that the starting point is behind it. This means that
the right-stick-steering conforms to the resulting movement of the ZX5 as long as it is not yawed by
the pilot.

Requirement: The ZX5 is flying and is at least 20m (65ft) away from the starting point.
Activation: Move the Easy/Ahead switch to the Ahead position.
Performance: The ZX5 turns in flight on the spot so that the starting point is behind it.

Easy Move

Extended automatic alignment function.
This function helps the pilot to manoeuvre the ZX5 more easily. To keep the steering more intuitive,

the alignment of the ZX5 is no longer considered during conversion of the steering commands. This
means that the ZX5 always flies in the direction in which the right stick is shifted regardless of where
the ZX5 is located. The imaginary line between the starting point and the ZX5 equals the stick axis
(forward – backward) of the right stick.

Requirement: The ZX5 is flying and is at least 20m (65ft) away from the starting point.
Activation: Move the Easy/Ahead switch to the Easy position.
Behavior outside the 20m (65ft) radius: From the view of the pilot, the ZX5 always moves

analogous to the movement of the right stick regardless of the position the ZX5 is directed.

Example 1 — Right stick to the front: the ZX5 always flies straight away from the
starting point.

Example 2 — Right stick to the back: the ZX5 always flies straight towards the starting
point.

Trimble ZX5 User Guide 37

3 Operating the ZX5 Using the R emote Control

Example 3 — Right stick to the right: the ZX5 flies spirally around the starting point.

Behavior inside the 20m (65ft) radius: Inside the 20m radius the ZX5 behaves slightly differently
to avoid the problems of the GPS inaccuracy. The directing of the ZX5 stays the same as it was on
the point of activation.

The following examples describe the behavior of the ZX5 when the Easy Move function is activated
inside the 20m radius, while the ZX5 is directed to the NW(45°):

Example 4 — Right stick pushed forward: the ZX5 flies toward the NW. After passing
the 20m radius it carries on flying in this direction, because it behaves as described in
example1.

Example 5 — Right stick pulled backward: the ZX5 flies toward the SE(225°/-135°).
After passing the 20m radius it changes direction and flies backward towards the
starting point as described in example2.

Example 6 — Right stick to the right: the ZX5 flies toward the SW(135°). After passing
the 20m radius it changes direction and flies spirally around the starting point as
described in example3.

Behavior while entering the 20m (65ft) radius: When the ZX5 is flying into the 20m radius, the
current orientation is fixed so that the ZX5 does not change direction while entering the 20m radius
if the right stick is held continuously.

Behavior while exiting the 20m (65ft) radius: When the ZX5 is flying out of the 20m radius, the
front is at the end of an imaginary line from the starting point to the ZX5. If applicable the ZX5
changes direction.

Flight modes for the DC-16 remote control

Note – The DC-16 remote control is available with the Inspection Module only.

Each flight mode is described below, starting with the lowest automatic level.

WARNING – The MAG/ALT switch on the remote control unit must be in the upper position at all

times. By default, this switch is disabled but if used incorrectly it may confuse the system and cause
loss of control of the ZX5. Failure to control the ZX5 can lead to a crash, resulting in equipment
damage, property damage, or personal injury.

WARNING – The pilot experience level for each flight mode is given below. Make sure you use only

the flight modes for which you have the appropriate level of experience. Flight modes suitable for
advanced pilots require advanced skills such as navigating against wind to avoid loss of control of the
ZX5. Failure to control the ZX5 can lead to a crash, resulting in equipment damage, property damage,
or personal injury.

WARNING – GPS functions are turned off automatically if the satellite receiving power drops below 6

satellites or the position accuracy rises above 8m (26ft). This may be due to, for example, satellite
issues, atmospheric disturbance or signal interference from other radio sources. In this situation, the
ZX5 reverts to Manual flight mode.

Trimble ZX5 User Guide 38

3 Operating the ZX5 Using the R emote Control

Manual flight

Flying without GPS functions.
In this mode the dynamic flight characteristics of the ZX5 can be fully used. The altitude and

direction are maintained automatically by magnetic field sensor (compass).

Activation: Move the CH/PH switch to the Manual Flight (backward) position.
Performance: In this mode all GPS functions are deactivated.
Pilot experience level: This flight mode is suitable for advanced pilots only. In windy situations the

ZX5 can be pushed away and rotated, unless the pilot navigates against it. Using this mode without
the appropriate level of experience can cause loss of control, leading to a crash.

GPS Position Hold

Automatic position stabilization by GPS.
In this mode the movement of the ZX5 is controlled by GPS. Speed is limited, and the rate of

acceleration and deceleration is lowered. If hovering in one position, the position is held
automatically. In flight the flight direction is maintained. The ZX5 also automatically compensates
for wind.

Activation: Move the CH/PH switch to the GPS Position Hold (middle) position.
Performance: The ZX5 maintains its position and direction even in windy situations.

Note – If a problem occurs during the flight and the ZX5 is unable to hold its GPS Position, for
example a propeller is damaged, then deactivate the GPS function and switch to Manual flight
mode to safely land the ZX5.

GPS Coming Home

Automatic return flight to the starting position.
Use this mode if the pilot loses orientation or if the mission is completed and the ZX5 should come

back to the starting position to land.

WARNING – In Coming Home mode, the ZX5 always takes the shortest, most direct way back to the

starting point. Make sure the ZX5 is flying at an appropriate altitude, with no obstacles, before
activating this mode.

WARNING –Always pay close attention to the ZX5 when Coming Home is activated, in case you need

to manually intervene. To cancel the Coming Home function, lightly move either the left or right stick.
The ZX5 changes to GPS Position Hold mode.

Activation: Move the CH/PH switch to the GPS Coming Home (upper) position.
Performance: The ZX5 flies back to the starting position.
Cancellation: This function can be canceled by slightly moving either the left or the right stick. The

ZX5 changes to GPS Position Hold mode.

Checking flight permissions and conditions

In the days before the flight, complete the following checks to make sure the flight can proceed.

Note – The use of unmanned aircraft in any national airspace system is regulated by the
applicable National Aviation Authority. The regulations for flying unmanned aircraft are subject to
change, sometimes without warning. It is the user’s responsibility to know and adhere to the
current laws for operating in the national airspace system. Trimble is not obliged to inform users
of changes to unmanned aircraft laws.

Trimble and Authorized Distribution Partners provide comprehensive training for the unmanned
aircraft system which includes recommended procedures to ensure the safety for the remote crew
members as well as the surrounding environment. It is the user’s responsibility to ensure safe
operations and adhere to safety and security measures required by the National Aviation
Authority. Trimble is not responsible for ensuring safe and secure operation of unmanned aircraft
by the user.

Checking flight permission

l Check if you need a permit to operate an unmanned aircraft in the airspace above the site.

l Make sure you understand the legal context for safe operation of an unmanned aircraft.

l Check for existing rules and standards with your local Civil Aviation Authorities (CAA).

l Make sure you have permission from the landowner.

l Make sure you have all other relevant permissions required for photography flights using

unmanned aircraft. In some countries you need permission from defense organizations, the
police, or a national geography institute to take pictures.

Checking weather

l In the days before the flight, check the TV weather broadcast or weather websites. This gives

you a good general idea of the weather for the next three to four days.

l For more accurate weather forecasts, consult and interpret aviation weather data through

various weather websites. You can also contact the national meteorological office or a local
meteorology office at an airport nearby.

l On the day of the flight, consult the Terminal Aerodrome Forecast (TAF) and METAR reports.

These are meteorological reports used in aviation.

l Make sure the weather conditions are within the operating limitations. See Operation

limitations, page 61.

the ZX5 and the batteries in a warm environment for as long as possible before the flight.

Checking the site

Note – When checking the site you should refer to the relevant AIP and NOTAM documents for
your region.

l Identify the airspace and geographic environment of the site.

l Check the relevant aviation charts and make sure the flight area is not near any of the

following areas:

l Forbidden airspace

l Airports, airfields (except with prior permission)

l Power plants (except with prior permission)

l Check the relevant aviation charts and take special care around:

l Parachute and parasailing jumping areas

l Winch areas

l High-pressure gas-releasing units (documented in AIPs or NOTAMs)

l Congested areas (for example, towns)

l Check if there are other aerial or ground activities planned, for example major public events.

Checking the operator

l Make sure the operator is certified to operate the ZX5.

l Check if the operator needs any additional permits, such as a remote operator license, a radio

certificate for use of the 2-way radio for communication with air traffic control, and so on.

l Be aware that the operator has final responsibility for the operation of the ZX5 and its

components.

Trimble ZX5 User Guide 50

4 Completing a Flight

l Make sure the operator is in good condition, both physical and mental.

l Keep log files of the operator hours and equipment used for each flight.

Flight time

The flight time depends on the used battery capacity, the weight of the battery pack, the weight of
the load and the outside temperature. It can vary between some minutes up to an hour.

You can ascertain the flight time for your ZX5 and camera by, for example, letting the ZX5 hover on
the spot at 5 m altitude until the battery voltage drops to 14.0 V. That is the maximum flight time,
which may be reduced depending on the dynamics of a particular flight and the age of the battery.

During every flight, note the flight time. The maximum flight time decreases over time as the
number of completed flights increases. If the maximum flight time is less than 50% of the flight time
when the battery was new then the battery is at the end of its life cycle. Replace the battery pack.

During flight, if the voltage level falls below the configured level a warning message sounds. Usually
you will hear this message at the end of a flight but as the battery ages the warning may sound
during flight. If you hear the warning message "Low battery" within the first few minutes of a flight
then immediately stop the flight and replace the battery pack.

Pre-flight checks

Before starting the ZX5, complete the following checks.

WARNING – Always keep a minimum safety distance of 10m (33ft) between the ZX5 and any person

who is not directly responsible for operating the aircraft. Never fly directly over gatherings of people
or traffic on the ground.

Equipment checks

l Make sure all batteries are charged (ZX5, remote control, camera, video receiver).

l Make sure the propellers are clean, free of damage and attached securely. Make sure screws

are fitted with loctite.

l Make sure the rotation direction of each propeller is correct.

l Make sure the landing gear is unfolded correctly and locked in place.

l Make sure all parts are tightly fixed.

l Make sure the ZX5 is well balanced in every direction.

Position the ZX5

l Position the ZX5 on even ground and orientate it correctly (yellow arms to the front).

l Make sure the skids cannot get caught from the ground.

4 Completing a Flight

Power on equipment

WARNING – Contact with moving parts can result in serious personal injury. Do not touch the ZX5

when the propellers are rotating. Before starting the motors make sure all personnel and objects are
at a minimum safety distance of 3m (10ft).

l Power on the remote control.

l Insert the ZX5 batteries, making sure to plug them in completely.

l Power on the monitor.

Check the camera

l Power on the camera and make sure the camera settings are set as described in Configuring

the camera settings, page 31.

l Make sure an empty, correctly formatted SDcard is inserted.

l Remove the lens cap.

l Take a test picture and check the camera picture is OK. Delete the test picture.

l Turn off the camera.

l Connect the hot shoe cable and trigger cable to the camera and make sure the trigger for the

camera works.

l Install the camera onto the camera gimbal:

l Make sure the screw is tight.

l Make sure the camera is mounted straight.

l Connect the trigger cable to the camera gimbal and connect the hot shoe cable to the

ZX5.

l Make sure the camera is free to move with the remote control (yaw and pitch).

Prepare for flight

l Make sure all switches on the remote control are in basic position, with GPS on or off as

desired.

l If possible, wait until the GPS reception reaches a precision of better than 4 m.

l Start the motors.

l Lift off.

l If you started without GPS functions, activate them and make sure that the ZX5 holds it

position.

Note – Be prepared, at all times, to deactivate the GPS functions and manually fly the ZX5. Always
observe the alignment and flight direction of the ZX5.

Trimble ZX5 User Guide 52

4 Completing a Flight

WARNING –Loss of control of the aircraft can result in equipment damage, property damage, serious

personal injury, or death. To minimize the risk of loss of control, observe the following at all times:
– Do not fly near other objects in the air.
– Do not fly on rainy or windy days or at night.
– Do not fly near high tension lines, electrical substations, high structures, or communication facilities.
– Never fly this aircraft where damage to property or injury to persons may result if loss of control
occurs.
– Always fly with line of sight to the aircraft.
– Always be prepared to make an emergency landing, without endangering others or damaging their
property.

Emergency failsafe functions

The system has the following emergency failsafe functions.

RC-loss (remote control loses contact)

RC-loss with GPS reception

After one second, the ZX5 automatically goes into Position Hold flight mode, waits 19 seconds and
then the ZX5 activates Coming Home mode and lands at the starting point.

If the remote control signal is picked up before the ZX5 has landed, the procedure is canceled and
the ZX5 switches to Position Hold flight mode and can be operated as usual.

RC-loss without GPS reception

The ZX5 immediately conducts an emergency landing on the spot. When it touches ground you
must manually switch off the motors.

WARNING – The motors must be left idling after landing until the battery is completely discharged,

since it is not possible to shut down the ZX5 motors completely after landing during RC-loss. The only
other possibility is to unplug the battery but the propellers are still moving and so the risk of severe
injury is high. For this reason, the motors must be left idling until the battery is completely discharged.
Doing so will, however, cause irreversible damage to the battery.

Low battery voltage (no RC loss)

If the battery voltage is very low the ZX5 automatically goes into Position Hold flight mode and then
conducts an emergency landing. The ZX5 can still be controlled by the pilot. When the ZX5 touches
ground the motors can be switched off using the remote control.

The very low voltage limit is 3.3 V per cell, equivalent to 13.2 V per battery.

Trimble ZX5 User Guide 53

4 Completing a Flight

Ending the flight

To end the flight:

l Land the ZX5 and power off the ZX5.

The motors reduce speed to idle and may appear to have stopped. However, the ZX5 is still
turned on. To avoid injury, you should immediately manually power off the ZX5 by pulling the
throttle stick completely back while simultaneously pulling the motor switch up to move it and
then moving the motor switch down to the motor stop position.

l Power off the gimbal.

l Power off the camera.

l Remove the ZX5 batteries.

l Power off the remote control

l Check the ZX5 for any damage.

WARNING – For safety reasons, after landing the motor speed can increase again after 2seconds

under certain circumstances. To avoid incremental movement caused by inaccuracies in the
GPSposition, immediately shut down the ZX5 motors completely, even if you intend to restart the ZX5.
To do this, pull the throttle stick on the remote control all the way down and move the motor switch to
the Off position. Attempting to restart the ZX5 when the motors are idling can cause loss of control of
the ZX5 and lead to a crash directly after take-off.

WARNING –Always inspect the ZX5 carefully after a hard landing or a crash. Damage to parts can

cause unstable flight characteristics, which may lead to loss of control of the aircraft. Failure to control
the ZX5 can lead to a crash, resulting in equipment damage, property damage, or personal injury.

Dealing with a crash

A crash is an accident associated with the operation of an aircraft in which:

l a person is fatally or seriously injured

l the aircraft sustains damage or structural failure

l the aircraft is missing or completely inaccessible

Note – A landing on the intended landing site that causes damage to the aircraft due to the
landing surface cannot be seen as a crash.

1. If a crash occurs which causes injuries or death, you must:

a. Contact the emergency services.

b. Help where necessary, without risking your own life.

c. Make a perimeter around the accident. Make sure no evidence disappears.

d. Notify your civil aviation authority (CAA).

2. If a crash occurs which causes damage to another object:

a. Contact the emergency services when necessary (for example, if gas, electricity, or water

supplies are affected).

Calibrating the compass

WARNING – If the compass is incorrectly calibrated, the ZX5 cannot fly correctly and may lead to loss

of control of the ZX5. Failure to control the ZX5 can lead to a crash, resulting in equipment damage,
property damage, or personal injury.

The compass must be recalibrated only in exceptional cases. Generally the calibration in the factory
is sufficient.

If you notice that the ZX5 does not fly directly to a waypoint, but flies around it, it can mean that
the compass is not calibrated correctly.

Testing the calibration of the compass

1. Take the ZX5 outside to a location where there are no metal objects within a 10m (33 ft)
radius.

2. Put the ZX5 on the ground and adjust it with the help of a commercially available compass so
that the ZX5 faces toward north.

3. On the display of the remote control, telemetry data page 1, you should see a compass
direction of about 0°. The tolerance is +/-2 degrees.

4. Tilt the ZX5 slightly to the front but keep it facing north. The display should change only very
minimally.

5. Return the ZX5 to facing north and then tilt it to the left. The display should still remain at
about 0°.

6. Turn the ZX5 90° to the right. The display should now show about 90°.

7. Turn the ZX5 again 90° to the right. The display should now show about 180°.

8. Turn the ZX5 again 90° to the right. The display should now show about -90°.

If any compass point is not displayed correctly (there is a difference of more than +/- 2°), the
compass must be calibrated.

Trimble ZX5 User Guide 58

Calibrating the compass

1. In the extended menu select Calibration – Compass.

2. Press menu button 3 (arrow down) to display Rotate around the Pitch-Axis.

3. To calibrate the X-sensor, lift the ZX5 up, align it toward north and turn it around its pitch-axis
until you hear a signal (peep). Now turn the ZX5 around this axis (at least one complete turn)
and keep turning it until the signals stop. At the same time, move the ZX5 slightly to the left
and right (about +/- 10 degrees).

4. Press menu button 3 (arrow down) again to display Rotate around the Roll-Axis.

5. To calibrate the Y-sensor, lift the ZX5 up, align it to 90° from north and turn it around the roll­axis until you hear a signal (peep). Now turn the ZX5 around this axis (at least one complete
turn) and keep turning it until the signals stop. At the same time move the ZX5 slightly to the
left and right (about +/- 10 degrees).

6. Press menu button 3 (arrow down) again to display Again around the Roll-Axis.

7. To calibrate the Z-sensor, lift the ZX5 up, hold it as before and turn it again around the roll-axis
until you hear a signal (peep). Now turn the ZX5 around this axis again (at least one complete
turn) and keep turning it until the signals stop. At the same time move the ZX5 slightly to the
left and right (about +/- 10 degrees).

8. Press menu button 3 (arrow down) to display Offset (XYZ).

9. Press the menu button 3 (arrow down) to display Scale (XYZ).

10. Test the calibration as described above. If the display differs in just one of the four points of

Tutorial 1: Position hold, flying in GPS mode

Purpose

Learning to fly the ZX5 with GPS, compass and altitude control.

Environmental conditions

Little or no wind, lots of space, no obstacles, over even and soft ground with low vegetation.

Degree of difficulty

Simple

Switch setting for starting

l Remote control DC-16:

CH/PH: GPS Position Hold (middle position)

l Remote control DS-14:

CH/PH: GPS Position Hold (middle position)
Easy/Ahead: Neutral (middle position)
Start/Landing: Neutral (middle position)

Process

1. Power on the ZX5.

2. Accelerate and let the ZX5 ascend up to about 5m (16 ft) height. To avoid a crash, make sure
that the skids do not get caught in vegetation.

3. Practice flying in all directions. Observe how the movement of the stick is converted by the
ZX5. Try flying various figures: circle, triangle, rectangle, figure of eight.

4. Try a different method: only use the right stick to fly forward and the left stick to steer the
direction.

5. Turn the ZX5 after a couple of meters flight path. You should end up at the starting point.

6. If you need a short break or lose the orientation, just let go of the sticks. The ZX5 will maintains
its position and hovers even if it is windy.

7. Observe the battery voltage and the flight time. Consider that the landing takes a couple of
minutes during your first flights and time it accordingly.

8. To land, reduce the acceleration slowly and attempt to descend vertically. On the last
centimeters take the throttle away completely and power off the ZX5 immediately after

touching the ground. You can also use the auto-landing function (only with integrated camera)
but you must still power off the ZX5 immediately after touching the ground.

Tip – To increase the degree of difficulty, perform this exercise in lightly windy conditions. Turn the
ZX5 occasionally around 90/180/270 degrees and maintain control.

Tutorial 2: Start, hover and land in manual mode

Purpose

Learning to fly the ZX5 without GPS functions, but with compass and altitude control. You should
repeat this exercise until you can start, land and fly with confidence.

Note – Although flying with GPS is easier, you must also be proficient at flying manually. GPS
signals can be interrupted for a variety of reasons, for example satellite issues, atmospheric
disturbances, or interference from other radio transmitters. In these situations, the GPS functions
will be turned off and the ZX5 must be flown manually.

Environmental conditions

Little or no wind, lots of space, no obstacles, over even and soft ground with low vegetation.

Degree of difficulty

Tutorial 4: Auto landing assistant

CAUTION –Only activate Auto landing when the ZX5 is flying with the camera fitted, as flying without

the camera installed changes the center of gravity of the ZX5. Activation of Auto landing without the
camera installed may lead to a crash.

CAUTION –On hilly ground the chosen landing place may be 10 m higher than the starting position. In

this situation the ZX5 may descend too fast and touch ground with too much speed, which can cause
damage. If you think the landing place may be higher than the starting position, land manually.

WARNING –Always pay close attention to the ZX5 when Auto landing is activated, in case you need to

manually intervene.

Purpose

Learning to use the Auto landing function.

Degree of difficulty

Simple

Switch setting for starting
