II. SAFETY
●Read Vesper & Vision GCS Manual to completion before operating
Vesper.
●Always ensure Vesper is at least 20 feet away from people before
takeoff.
●Be mindful of where your hands and other body parts are, especially
when Vesper is powered on.
●Only launch Vesper from the operator’s hand using the Safety Rotor
Set. Never attempt to launch from, or land to, the operator’s hand
with the Recon Rotor Set.
●When using the Recon Rotor Set, keep Vesper at least 20 away from
personnel. Never attempt to touch Vesper while it is in flight or while
the propellers are in motion.
●While manually operating Vesper, only fly where you can see. Vesper
does not have lateral obstacle avoidance; therefore, it is the
operator’s responsibility to prevent collisions. Exercise extreme
caution when flying in a direction where the camera doesn’t provide
clear visibility.
●Plan takeoff and landing to protect people and Vesper. Designate a
launch and landing spot at a location clear of obstacles and people.
●Before using the Return To Home (RTH) feature, ensure settings are
adjusted for an appropriate return altitude over terrain.
●Follow all pre- and post-flight operational guidelines and storage
procedures described in this manual.

IMPORTANT:
WHEN VESPER IS CONFIGURED WITH THE RECON ROTOR SET,
NEVER HOLD VESPER BY HAND WHILE PROPELLERS ARE IN MOTION.

FAILSAFE TRIGGERS & EMERGENCY PROCEDURES
To program safe behavior for various scenarios:
●Click on the “Q” Ground Control logo on the top left-hand side
●Navigate to the Vehicle Setup menu at the top of the screen
●Select the Safety option
The sections below detail how to program for specific situations:
6

LOW BATTERY
Vesper will automatically land and shut off once the battery level reaches 5%.
The GCS will give multiple visual pop-up warnings in advance of the automatic
landing. The operator can override the final 5% automatic landing with stick
inputs, but should be aware that doing so risks loss of the aircraft. The low
battery preset limits can be modified in the Safety options.
By clicking the Failsafe Action dropdown menu, the operator can define low
battery behavior. In this menu, the operator can choose at what % battery level
to send a warning notification, and enter the failsafe setting or emergency
setting.
LOSS OF GPS
Vesper can maintain position using visual inertial odometry (VIO) and optical
flow in the event of GPS loss as long as scene illumination is greater than 10 -
50 lux (depending on surface texture). If Vesper is unable to maintain position
and has lost the control link, it will land in a level orientation. VIO will drift by
approximately 7 meters for every 100 meters of travel.
7

RADIO CONTROL (RC) LOSS
Radio Control (RC) Loss means Vesper has lost connection to the Ground
Control Station (GCS). In Q → Vehicle Setup → Safety, the operator can
preemptively choose what actions Vesper will take should this scenario occur.
By clicking the Failsafe Action dropdown menu, the operator can designate the
best option for Vesper and determine how many seconds of data link loss will
lead to time out.
FAILSAFE LANDING LOCATION
By default, Vesper will return to its launch position when facing a critical
condition, such as low battery or GPS loss. To modify these settings, select the
Failsafe Trigger settings in Q → Vehicle Setup → Safety.

III. ENVIRONMENTAL CONDITIONS
RANGE OF USE:
●Optimal flight conditions = open areas devoid of obstacles, crowds,
power lines, trees, and bodies of water.
●To be field serviceable and to minimize dirt ingress, Vesper’s motors
are partially sealed. Nonetheless, avoid contact with debris, sand and
dirt whenever possible.
●Vesper is safe to fly in heavy rain; however, Vesper should never be
submerged in water.
●To minimize radio link and GPS interference, avoid high levels of
electromagnetism such as power lines and electrical substations.
●When operating Vesper in cold conditions, store Vesper’s battery close
to your body to maximize performance.
●Vesper uses a magnetometer for vehicle heading. Do not take off from
any magnetic or steel structures.
●Vesper maximum operating temperature is lower on the ground than
in the air, as Vesper uses forced convection from the propellers for
cooling.
Temperature Operating Conditions are as follows:

IV. SETUP
UNPACKING AND POWERING
1. Remove Vesper from the field case and fully unfold all four arms.
2. Power on Vesper by grabbing battery on left and right sides; a beep,
followed by a series of tones and illuminated tail LEDs indicate
success.
3. Turquoise LED light will turn green or blue once unit is fully booted, as
follows:
4. Power on the Vision GCS by pressing the Power button and unfolding
both antennas.
5. If Vesper has not yet been paired with Vision GCS, connect Vesper to
Vision GCS by following the pairing instructions below.
6. If Vesper has been paired previously with Vision GCS, telemetry and
video should appear after approximately 85 seconds.
