SAFETY PRECAUTIONS
Follow these safety precautions when operating this or any model drone.
• Do not touch the spinning blades or fly over people or animals.
• Keep your face and body as well as all spectators away from the rotors whenever
the battery is connected.
• Stay clear of buildings, trees and power lines. AVOID flying in or near crowded
areas. DO NOT fly close to people, children or pets.
• Maintain a safe pilot-to-drone distance while flying.
• Your Sync 251 Drone should not be considered a toy, but rather a small, working
model. If not operated correctly, the model could possibly cause injury to you or
spectators and damage to property.
• Do not alter or modify the model, as doing so may result in an unsafe or unflyable
model.
• You must check the operation of the model before every flight to ensure that the
model has remained structurally sound.
LOCATION PRECAUTIONS
The Sync™ 251 drone uses optical flow technology to hold it in place. This works by
taking repeated pictures of the ground and comparing the pixels from one picture to
the next very fast. If it senses a change, the sensor will command the drone to adjust
its position. While this technology is incredible, there are some things to watch for
that can confuse the sensor:
• Floors that are shiny and reflective may cause drifting as it tries to follow light reflections.
• Surfaces that are very consistent, like black asphalt, snow, or uniform tile floors,
can also confuse the sensor and cause drifting.
• Flying over water or anything that can move will cause the drone to drift.
• When it is windy outside and the grass or flowers are moving, the drone may drift.
If you find it is drifting where you are at, simply move to an area where the sensor
can see stationary objects.
CHARGING WARNINGS
CAUTION: All instructions and warnings must be followed exactly.
Mishandling of Li-Po batteries can result in a fire, personal injury and/or
property damage.
• NEVER LEAVE CHARGING BATTERIES UNATTENDED.
• NEVER CHARGE BATTERIES OVERNIGHT.
• By handling, charging or using the included Li-Po battery, you assume all risks
associated with lithium batteries.
• If at any time the battery begins to balloon or swell, discontinue use immediately.
If charging or discharging, discontinue and disconnect. Continuing to use, charge
or discharge a battery that is ballooning or swelling can result in fire.
• Always store the battery at room temperature in a dry area for best results.
• Always transport or temporarily store the battery in a temperature range of
40–120º F (5–49° C).
• Do not store battery or model in a car or direct sunlight. If stored in a hot car, the

Basic Flight After initially connecting the battery, move the left stick up then down
to arm the motors. Press the Motors Start button until the motors start to spin. Press
again and the drone will auto-take off and hover about 3 feet (1 meter) above the
floor. OPTION: After the motors are spinning, the throttle stick can also be used to
manually take off. Slowly advance the throttle and release it when you reach the
desired height.
The control sensitivity should be in the low setting if flying indoors. Small
movements of the pitch, roll and yaw control sticks should be used to move. Raise
or lower the throttle stick to change the altitude. When the drone is at the desired
height, release the throttle stick so the Altitude Hold sensor can maintain and hold
height. If you get into trouble and see that the drone is going to crash, press and
HOLD the MOTOR START/STOP button to stop the motors as soon as possible.
Sensitivity Adjustment Push down on the right stick to change the sensitivity
of the controls.

Low Voltage Alarm The LEDs on the arms will flash when the battery
voltage is getting low. Land the drone as soon as possible and charge the
battery. The battery must be charged before it is stored. ALWAYS disconnect
the battery when it’s not in use!
Headless Mode
the drone movements will be relative to the
controller no matter which way the drone
is pointing. When you push forward on the
controller for example, the drone moves away
from you even if the camera is pointing to the
side or at you. When the Headless Mode is
active, the LEDs will flash slowly. For Headless
Mode to work:
1. The tail of the drone MUST face the pilot when the drone is first plugged in
and set down.
2. The pilot must not change position or direction after the controller and drone
are linked.
When you active this mode,
Optics On/Off The optics work great for
holding the drone in position. However, if you
want more freedom, you can turn them off by
pushing the top button. The Red LED’s will flash
fast and the Blue/Purple LED on the transmitter
(for Low/High sensitivity) will turn to (faint orange
and bright orange).

FLYING FPV
Your phone can be mounted in the
holder on the controller or inserted
in the VR headset (DIDZ1558) for a
more immersive feel.
The range of the 5G Wi-Fi
FPV camera is about 200 feet
outdoors and 50 feet indoors,
but may be less if the location
has a lot of electromagnetic
interference or metal objects in
the walls.
If you are new to FPV, start by
flying line of sight until you can
maneuver the drone without
having to think about which
control to use. Practice by keeping both sticks centered and making only
small movements.
When you are ready to start FPV, we recommend that a spotter be available to
tell what the drone is doing. Master each of the following steps before moving to
the next one.
Step 1
• Take off.
• Hover at about 3 feet.
• Move a few inches to the right in any direction and return to the hover point. Repeat
moving left, forward, and backward.
• Slowly land.
The goal is to get used to the view from the camera, the sensitivity of the
controls, and judging your height.
Step 2
• Take off.
• Fly slowly (about 10 feet away.)
• Turn around and return to the launch point.
• Slowly land.
The goal is to maintain your height until you are ready to land.
Step 3
• Set up a course.
Keep it simple at first. When you can fly while maintaining your altitude, set up a
course with gates or obstacles at different heights.
The goals are to fly the entire course while maintaining the altitude and increase
your speed around the course.
Motor Replacement
1. Remove the two
screws from the foot.
2. Carefully remove the
foot. The motor will
unplug and come out
with the foot.
3. Plug in the new motor
and place it into the
frame so the wires line
up together.
4. Replace the foot carefully, so the wires get routed without getting pinched.
