Aircraft This section introduces functions and features of the MEW4-1. Flight Modes Your MEW4-1 has 3 flights modes:

GPS mode: ON 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). 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. 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. Pic. 1 Pic. 2

MEW4-1 User Manual Return to Home (RTH) 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. GPS Description Home Point 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.

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. 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 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. Pic. 1 Pic. 2

MEW4-1 User Manual 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. 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.

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. 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. Vision System Consisted by camera and ultrasonic sensor , 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.

-8-

Vision Positioning System function 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. MEW4-1 User Manual 3m

The precision of the vision 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. Keep sensors clean at all times. The vision 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.

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.
