Appendix

Unfold the aircraft
The aircraft is folded inside the package. Please unfold the aircraft before use.
● Equipped with Vision System and GPS System, your MEW4-1 can precisely position, hover and automatically return. It is also capable of
flying in the intelligent flight modes like Point of Interest, Follow Me and Waypoint Flight. Features a single-axis gimbal, your MEW4-1 can
shoot 2K, 2-megapixel 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 “X-DRONE” APP. Foldable hand sticks and pull-out holder design make the remote controller easier to operate and carry.

Install the battery of remote controller
Prepare the Remote Controller
!● Insert batteries with correct polarity.
● Non rechargeable batteries are not to be charged; the transmitter need 2*AA batteries for work.

● Do not mix alkaline, standard (carbon-zinc), or rechargeable (nickel-cadmium) batteries.
● Rechargeable batteries are to be removed from the aircraft before being charged.
● Rechargeable batteries are only to be charged under adult supervision.
● Exhausted batteries are to be removed from the aircraft.
● The supply terminals are not to be short-circuited.
Step 1: Unfold the hand sticks and open the battery door (Pic. 1);
Step 2: Install 2*AA batteries into the battery compartment according to the given polarity (Pic. 2);
Step 3: Close the battery compartment (Pic. 3).

Battery installation
!
Step 1. Insert the battery into socket at the top of the aircraft (Pic. 1);
Step 2. Slide the battery into the compartment by pushing with appropriate force. Make sure that you hear a click sound indicating the
battery is firmly installed (Pic. 2).
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-cut during the flight.

Flight Modes
Pic. 1 Pic. 2
GPS mode: ON
Your MEW4-1 has 3 flights modes:
Gesture mode: OFF
Slide the button down to “OFF” (Pic. 2), the aircraft is in Gesture mode that GPS is not used for positioning, and the aircraft only uses the
barometer to maintain altitude. The aircraft will not fly with precise positioning and hovering. Gesture mode requests pilot with good skill.
In Gesture Mode, the aircraft cannot position itself or brake automatically, which increases the risk of potential flight hazards. The aircraft
will be also more easily affected by its surroundings. Environmental factors such as wind can result in horizontal shifting, which may present
hazards, especially when flying in confined spaces.
Aircraft
This section introduces functions and
features of the MEW4-1.
Vision positioning mode:
Once the GPS signal is weak or unavailable and the flying altitude is less than 3 meters, the aircraft will automatically enter into vision
positioning mode. Assisted by the vision system, the aircraft could perform precise positioning.
Slide the button up at the right side to position “ON” (Pic.1), the aircraft is in GPS mode and 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 Gesture mode (flying altitude ≥ 3 meters) or vision
positioning mode (flying altitude 3 meters).

Smart RTH
MEW4-1 User Manual
!● 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 takeoff, 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.
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 in the “X-DRONE” APP (Pic. 2) and then follow the on-screen instructions to initiate Smart RTH. During the smart RTH, you can
use the remote controller to guide the aircraft around obstacles. You can press the RTH button again to exit RTH procedure and regain
control of the aircraft.

Low Battery RTH
The low battery level failsafe is triggered when the intelligent battery is depleted to a point that may affect the safe return of the aircraft.
Users are advised to return home or land the aircraft immediately when prompted.
1. When the aircraft rear lights flash slowly, battery icon “ ” is shown on the remote controller or on the “X-DRONE” 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.

MEW4-1 User Manual
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 re-established.
!Attention: When the aircraft is automatically return home with Low Battery RTH function activated, you can not cancel
the RTH procedure by pressing the RTH button to regain control of the aircraft.
2. When the aircraft rear lights flash slowly, battery icon “ ” is shown on the remote controller or on the “X-DRONE” 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 aircraft flying altitude is less than 15 meters or the
flying distance is less than 15 meters, the aircraft will automatically land to the ground.
Consisted by camera ①and ultrasonic sensor ②, the Vision System locates at front bottom of your MEW4-1. It is a positioning system
that is composed by image sensor and ultrasonic sensor. Your MEW4-1 acquires its location through using the camera sensor to detect the
ground texture and visible features. Meanwhile, assisted by the ultrasonic sensor, your MEW4-1 could determine the altitude where it stays,
which could better insure the fly safety and gain precise positioning.
