EX3 User Manual

Product Profile

This section mainly introduces functions and installation guidelines of EX3 and lists the components of the aircraft and remote controller.

Introduction

• Equipped with Vision System and GPS System, your EX3 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 EX3 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.
• Maximum flight speed is 40km/h and maximum flight time is 22 minutes.

Prepare Your EX3

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).

Step2: Repeat again to unfold front arms (Pic. 2).

Aircraft

Flight Modes

Your EX3 has two 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. When GPS signal is weak or the aircraft's compass is interfered, the aircraft will automatically enter into Gesture Mode.

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 Status Indicator Lights

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.

⚠️ 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

Use the [RTH Icon] button on the remote controller or tap the RTH button in the "X-DRONE" APP and follow the on-screen instructions when GPS(more than 7 satellites is presented) is available 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 Eachine 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 [Low 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 100 meters or the flying distance against the home point is beyond 300 meters.

2. When the aircraft rear lights flash slowly, battery icon [Low 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

Made up by camera 1, camera 2 and ultrasonic sensor 3, the Vision System locates at front bottom of your EX3. It is a positioning system that is combined by image sensor and ultrasonic sensor. Your EX3 acquires its location and perceives obstacles through using the camera sensor to detect the ground texture and visible features. Meanwhile, assisted by the ultrasonic sensor, your EX3 could determine the altitude where it stays, which could better insure the fly safety and gain precise positioning.

Detection range

Detection range of Vision System indicates as below. Your EX3's detection function will be not so effective that it could not avoid the obstacles that is out of its detection range. You have to be careful once you fly when your EX3 is not flying within its detection range.

Positioning System function

The Positioning System is typically used in indoor environment when GPS is weak or unavailable. It works best when the aircraft altitude is less than 10 meters.

⚠️ 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 10 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.

Aircraft Operations

Signal connection between the aircraft and remote controller

• Keep pressing the red button "[Lock Icon]" and turn on the remote controller (Pic. 1). The remote controller makes 2 beep sounds, and the indicator light "[Indicator Light Flashing]" keeps flashing; the remote controller is under signal connection status.
• Power on the aircraft (Pic. 2). The aircraft will make beep sounds with front and rear lights flashing and will automatically link to the remote controller. Once the remote controller sends out a long beep sound and the indicator light of the remote controller turns from flashing to solid on and the signal icon "[Signal Connected Icon]" is shown on the LCD screen, it means that signal connection is succeeded.

⚠️ Signal connection is done once for all if the remote controller is not linked to other aircraft.

Set the connection one by one to avoid signal connection error.

Aircraft initialization detection

After signal connection, the aircraft enters into initialization detection procedure with front and rear lights flashing red, green and yellow alternatively. Make sure that the aircraft is set on a flat and still surface for the initialization detection. The aircraft initialization detection takes about 8 seconds. Once the remote controller sends out "Di Di" sounds and the aircraft front and rear lights flash yellow alternatively, initialization detection is completed.

⚠️ Attention: Make sure that the aircraft is set on a flat and still surface for the initialization detection.

Aircraft compass calibration

1. Compass calibration should be performed after successful aircraft initialization detection.
2. Aircraft compass calibration should be done for every flight. That is to say, if changing new battery or the battery is reinstalled, compass calibration should be done again.

Two steps of compass calibration:

Step 1: Horizontal calibration

After successful aircraft initialization detection, the aircraft front and rear lights flash yellow alternatively. Hold the aircraft horizontally and rotate it 360 degrees along the central axis for about 3 circles. The aircraft front and rear light will change from flashing yellow alternatively to flashing green alternatively when horizontal calibration is completed.

Step 2: Vertical calibration

Hold the aircraft with camera facing up, and rotate it 360 degrees along the central axis for about 3 circles until the front and rear lights of the aircraft change from flashing to solid on, the compass calibration is successful.

⚠️ Attention: To fly at GPS mode, please choose an open and wide space for the flight, and make sure that the satellite amount is over 7.

⚠️ Please do not calibrate the compass in strong magnetic area, such as magnetic field, parking place or construction areas with underground reinforcement.

⚠️ Please do not carry magnetic materials with you (such as keys, cell phones, etc) when calibrating compass.

⚠️ Please keep away from big metal when calibrating compass.

Gyroscope calibration

After the aircraft and the remote controller are banded, set the aircraft on flat ground and follow the indication photo as below to calibrate the gyro. Once the aircraft front lights turn from flashing to solid on, it means that the gyro calibration is succeeded.

⚠️ The gyroscope calibration has been done by factory default. Gyroscope calibration is no need to be performed unless the aircraft can not exit the aircraft initialization detection procedure while the aircraft initialization detection is finished.

⚠️ Please make sure to set the aircraft on horizontal surface when performing calibration, failure to do this will affect the flight.
