Unfold the aircraft
The Aircraft is folded inside the package. Follow the steps as below to unfold the aircraft.
Step 1: Unfold the rear arms (Pic. 1);
Step 2: Repeat again to unfold front arms (Pic. 2).
● Equipped with Optical Flow Positioning and GPS System, your D88 can precisely position, hover
and automatically return. It is also capable of flying in the intelligent flight modes such as Point of
Interest, Follow Me and Waypoint Flight. Features a single-axis gimbal, your D88 can shoot 2K
photos and adjust camera angle 90 degrees in flight.
● The aircraft and camera can easily be controlled using the onboard buttons. Real-time images and
aircraft data information can be shown on the “Potensic-M2” APP. Foldable hand sticks and
pull-out holder design make the remote controller easier to operate and carry.
● Maximum flight speed is 40km/h and maximum flight time is 22 minutes.

Battery installation
!
Slide the battery into the battery compartment at the rear of the aircraft by pushing with appropriate
force. Make sure that you hear a click sound indicating the battery is firmly installed.
Attention: The battery should be installed firmly, failure to do so may affect the flight
safety of your aircraft. The aircraft may crash due to power-disconnecting
during the flight.

Flight Modes
Pic. 1 Pic. 2
GPS mode: ON
Your D88 has 3 flights modes:
Gesture mode: OFF
Turn off the GPS mode, then the aircraft enter into Gesture mode. The positioning system will be
shut down, and functions under GPS mode can not work. The drone can not accurate hover at a
fixed point, so please land your drone in a safe place in time if you can not control it well.(You
should be aware that week GPS signal may cause your drone out of control)
Optical flow positioning:
Once the GPS signal is weak or unavailable and the flying altitude is less than 3 meters, the aircraft
will automatically enter into optical flow positioning. Assisted by this function, the aircraft could
perform precisely positioning.
Aircraft
This section introduces functions and
features of the D88.
Turn on the GPS mode (Pic.1), the aircraft can precisely position and hover by the assistance of
the GPS module.
(Warm Tips: When the GPS signal is weak, the aircraft will automatically enter into Geature
mode (flying altitude≥3 meters) or optical flow positioning mode (flying altitude<3 meters).

!● Aircraft can not avoid obstacles when it is flying back with the RTH function
initiated.
● Aircraft can not return to the Home Point when the GPS signal is weak or
unavailable.
● Aircraft will stop ascending and immediately return to the Home Point if user
moves the throttle stick in the aircraft reaches 15 meters altitudes or beyond
during Smart RTH.
● If there is no GPS signal and the remote controller signal lost for more than
6 seconds, the aircraft can not Return-to-Home but descend slowly until land
to the ground and lock the aircraft.
The Return-to-Home (RTH) function brings the aircraft back to the last recorded Home Point.
There are 3 types of RTH: smart RTH, low battery RTH and failsafe RTH. This section describes
these 3 scenarios in detail.
Return to Home (RTH)
Home Point
GPS Description
If a strong GPS signal (satellites over 7) was acquired before taking-off, the
Home Point is the location from which the aircraft launched. The GPS signal
strength is indicated by the GPS icon( ). The aircraft rear indicator lights
will blink rapidly from yellow color to green color when the home point is
recorded.
Front and rear lights flash once, stop
for 1.5 second. Something wrong with the gyroscope.

Smart RTH
When the GPS signal is available (more than 7 satellites is presented), use the RTH button on the
remote controller (Pic. 1) or tap the RTH button on the App (Pic. 2) and then follow the
on-screen instructions to initiate Smart RTH. During the smart RTH, you can operate the joystick to
control your drone to avoid obstacle. You can press the RTH button again to exit RTH
procedure and regain control of the aircraft.
Low Battery RTH
Failsafe RTH
If the Home Point was successfully recorded and the compass is functioning normally, Failsafe RTH
will be automatically activated if the remote controller signal is lost beyond 6 seconds. Return-to-Home
can be cancelled by the pilot, allowing them to regain control when the remote controller signal
connection is reconnected during the returning.
!Attention: When the aircraft is automatically return home with Low Battery RTH
function will be activated, you can not cancel the RTH procedure by
pressing the RTH button to regain control of the aircraft.
1. When the aircraft rear lights flash slowly, battery icon “ ” is shown on the remote controller or
on the APP. And steady “beep beep beep... beep beep beep” sound is heard. At this moment,
the aircraft will automatically return to the Home Point if the flying altitude is beyond 50 meters
or the flying distance against the home point is beyond 100 meters.
2. When the aircraft rear lights flash slowly, battery icon “ ” is shown on the remote controller or on
the APP. And steady “beep..beep...beep” sound is heard. At this moment, the aircraft will
automatically return to the Home Point if the flying altitude is beyond 15 meters or the flying
distance against the home point is beyond 15 meters. If the distance is within 15m, the drone will
land on the ground.

Optical Flow Positioning
The Vision Positioning System is typically used in indoor environment when GPS is weak or
unavailable. It works best when the aircraft altitude is less than 3 meters.
Optical Flow Positioning
Consisted by camera ①and ultrasonic sensor ②, the Optical Flow Positioning locates at front bottom
of your D88. It is a positioning system that is composed by image sensor and ultrasonic sensor. Your
D88 acquires its location through using the camera sensor to detect the ground texture and visible
features.
Meanwhile, assisted by the ultrasonic sensor, your drone could determine the altitude where it stays,
which could better insure the fly safety and gain precisely positioning.

Potenstic D88 User Manual

!The precision of the optical flow positioning system is easily affected by the light
strength and features of the surface textures. It would happen that the ultrasonic sensor
could work normally to detect the altitude when it is flying over objects that is made by
sound-absorbing materials. Once the image sensor and ultrasonic sensor are both not
available, your aircraft will switch to Gesture mode automatically. Be cautious to operate
the aircraft in the following situation:
1. Fly fast at an altitude below 0.5m.
2. Fly over monochrome surfaces (like pure black, pure red, pure red and pure green).
3. Fly over strong light reflective surfaces or surfaces prone to reflection.
4. Fly over water or transparent object surfaces.
5. Fly over moving object surfaces (such as crowds, swaying juggles and glass).
6. Fly over an area where light changes dramatically and rapidly.
7. Fly over surfaces extremely dark (lux<10) or extremely bright (lux>10,000).
8. Fly over material surfaces that is good at absorbing ultrasonic waves (like thick carpet).
9. Fly over surfaces without clear textures.
10. Fly over surfaces with highly repeating textures (small grid brick in the same color).
11. Fly over surfaces that are tilting over 30 degrees (could not receive the echo of the
ultrasonic wave).
12. Flying speed should be controlled not to be too fast. When the aircraft is 1 meter
against the ground, the flying speed should not be over 5m/s; When the aircraft is 2
meter against the ground, the flying speed should not be over 14m/s.
!Attention: Keep animals away from the aircraft when the vision system is activated.
The ultrasonic sensor emits high frequency sounds that are audible to
some animals.
● Keep sensors clean at all times.
● The optical flow positioning system is only effective when the aircraft is within the
altitude range of 3 meters.
● Make sure that the light is bright enough and the surfaces is with clear textures so that
the vision system can acquire the movement information through recognizing the
ground textures.
● The vision system may not function properly when the aircraft is flying over water, low
light ground and surfaces without clear patterns or textures.
● Do not use other ultrasonic device with a frequency of 40KHz when the vision system
is in operation.
