Eachine EX3 Drone User Manual

Flight Modes

The EX3 offers two flight modes:

• GPS mode: ON

When the switch on the right side is set to "ON" (Pic. 1), the aircraft operates in GPS mode, utilizing the GPS module for precise positioning and hovering. If the GPS signal is weak or the compass is interfered with, the aircraft will automatically switch to Gesture Mode.

• Gesture mode: OFF

When the switch is set to "OFF" (Pic. 2), the aircraft operates in Gesture mode. GPS is not used for positioning; instead, the barometer maintains altitude. This mode does not provide precise positioning or hovering and requires skilled piloting. In Gesture Mode, the aircraft cannot self-position or brake automatically, increasing the risk of flight hazards. It is also more susceptible to environmental factors like wind, which can cause horizontal shifting, especially in confined spaces.

Diagram Description: Two images of the remote controller's GPS mode switch. Pic. 1 shows the switch in the 'ON' (GPS) position. Pic. 2 shows the switch in the 'OFF' (Gesture) position.

Aircraft Status Indicator Lights

The aircraft's lights indicate its status:

Return to Home (RTH)

The RTH function guides the aircraft back to the last recorded Home Point. There are three types of RTH: Smart RTH, Low Battery RTH, and Failsafe RTH.

• Smart RTH: Initiated via the RTH button on the remote or the "X-DRONE" APP when GPS signal is strong (over 7 satellites). The pilot can guide the aircraft around obstacles during Smart RTH. Pressing the RTH button again exits RTH and restores control.
• Low Battery RTH: Triggered when the intelligent battery is depleted to a level that may affect safe return. Users are advised to return home or land immediately.
• When rear lights flash slowly and the battery icon "<0xF0><0x9F><0x94><0x8B>" is displayed, the aircraft returns home if altitude is over 100m or distance is over 300m.
• When rear lights flash slowly and battery icon "<0xF0><0x9F><0x94><0x8B>" is displayed with a steady "beep..beep...beep" sound, the aircraft returns home if altitude is over 15m or distance is over 15m. If altitude or distance is less than 15m, it lands.

⚠️ Attention: When Low Battery RTH is active, pressing the RTH button cannot cancel the procedure.

• Failsafe RTH: Automatically activated if the remote controller signal is lost for over 6 seconds, provided the Home Point was recorded and the compass is functioning. RTH can be cancelled by the pilot upon signal re-establishment.

RTH Limitations:

• Aircraft cannot avoid obstacles during RTH.
• RTH may fail if GPS signal is weak or unavailable.
• During Smart RTH, if the throttle stick is moved when the aircraft reaches 15m altitude, it will ascend and return home.
• If GPS and remote controller signals are lost for over 6 seconds, the aircraft will descend slowly and land.

Diagram Description: An illustration showing the remote controller with the RTH button highlighted. A table details the RTH scenarios based on GPS signal strength and satellite count.

Vision System

The Vision System, located at the front underside of the EX3, comprises two cameras and an ultrasonic sensor. It functions as a positioning system that uses image and ultrasonic sensors to acquire location, perceive obstacles by detecting ground texture and features, and determine altitude for safe and precise positioning. The system is most effective indoors when GPS is weak or unavailable, and at altitudes below 10 meters.

Diagram Description: An illustration of the drone's underside, with numbered labels pointing to Camera 1, Camera 2, and Ultrasonic Sensor 3. Another diagram shows a cone representing the detection range, and a third shows the drone indoors with lines indicating a 10m positioning range.

Detection range: The Vision System's detection is limited. Obstacles outside its range cannot be avoided. Be cautious when flying outside the detection range.

Positioning System function: Primarily for indoor use when GPS is weak or unavailable, optimal at altitudes below 10 meters.

⚠️ Attention: The precision of the vision system is affected by light strength and surface textures. It may not function correctly over monochrome, highly reflective, water, transparent, or moving surfaces, extremely dark/bright surfaces, sound-absorbing materials, or surfaces with repeating textures or tilting over 30 degrees. Flying speed should be controlled, especially near the ground (e.g., not over 5m/s at 1m altitude, not over 14m/s at 2m altitude). Keep sensors clean, ensure sufficient light, and use clear textures. Do not use other 40KHz ultrasonic devices simultaneously. Keep animals away as the ultrasonic sensor emits audible high-frequency sounds.

Aircraft Power Switch

Turn on the aircraft: After battery installation, press the power switch for 3 seconds. The aircraft will beep, and its lights will flash.

Turn off the aircraft: Press the power switch for 3 seconds. The aircraft lights will turn off, and the EX3 will power down.
