Chapter 2 Flight Safety
2.1 Flight Environment Requirements
- Do not fly in bad weather, such as strong winds (wind speed greater than 12 m/s). When flying in the rain, always follow the requirements described in the IPX4 class of protection instructions.
- Ensure that the aircraft takes off on an open, unobstructed and flat ground, and needs to be far away from surrounding buildings, trees, people, water surface, etc. Please keep flying within the sight distance. If over-the-horizon flight is required, please ensure that the aircraft is in good condition and the user has the corresponding qualification. Before flying, please confirm whether it meets the requirements of local regulations for over-the-horizon flight.
- Do not take off from the surface of moving objects (such as moving cars, boats).
- Please avoid sand and dust road when landing, otherwise it will affect the service life of the motor.
2.2 Wireless Communication Requirements
- Make sure that the aircraft antenna is intact and not damaged or detached.
- Ensure that the aircraft is operated in open areas or on high ground. Tall reinforced buildings, mountains, rocks, and woods may block the GNSS and map-transmitted signals of the aircraft.
- As other wireless devices will interfere with the remote controller, it is recommended to use the remote controller to control the aircraft flight around the high-power radio, away from the base station and other strong interference equipment.
- Please be careful when flying near the source of electromagnetic interference, and continuously observe whether the image transmission screen of UniGCS App is stuck and whether the signal strength of the image transmission is weak. Sources of electromagnetic interference include, but are not limited to: high-voltage power lines, high-voltage transmission stations, mobile phone base stations, and television broadcast towers.
Chapter 3 Automatic Return
The aircraft has an automatic return function, which is mainly divided into return, low-power return and out-of-control return according to the return trigger mode. If the return point is successfully recorded before takeoff and the GNSS signal is good, the aircraft will automatically
return to the return point and land when the user actively starts the return, the aircraft’s low battery triggers the intelligent low battery return, and the loss of communication signal between the remote controllerler and the aircraft triggers the uncontrolled return. In the process of automatic return, the user can not adjust the direction of the nose, and can not control the aircraft to fly to the left and right.
3.1 Manual Return
Manual return can be started by clicking the RTL button on the remote controllerler, and the heading cannot be controlled during the return process. During the return flight, after a short press of the RTL button or the emergency stop button on the remote controllerler to exit the return flight, the user can re-control the aircraft.
1. The aircraft records the return point.
2. Trigger the return condition (triggered by the user using the remote controller or by the aircraft low battery).
3. The aircraft confirms the return point and automatically adjusts the nose direction.
4. The aircraft automatically flies above the return point, enters the landing protection process, and the aircraft lands or hovers directly. For details, see Landing Protection Function “.
3.2 low battery return
In order to prevent unnecessary danger due to insufficient battery power, the aircraft will intelligently judge whether the current power is sufficient according to the position information of the flight. If the current power is only enough to complete the return process, “Low Battery!” It will be displayed on the status alarm message of the corresponding ground station, which will prompt the user whether the return flight is required. If the user does not make a choice within 10 seconds, the aircraft will automatically enter the return flight after 10 seconds. During the return flight, you can press the remote controller return button or emergency stop button once to cancel the return flight.
Low battery return occurs only once during the same flight. If the user cancels the low-power return reminder and continues to fly, it may cause the aircraft to make a forced landing when the aircraft returns due to insufficient power, causing the aircraft to be lost or crash.
If the aircraft continues to fly with low power, when the power is only enough to achieve landing, the aircraft will be forced to descend and cannot be canceled. In the process of forced landing, the user can control the aircraft to move left and right and choose a suitable place to land, but the continuous descent behavior of the aircraft cannot be canceled.
RTL_ALT: The lowest altitude before the aircraft returns.
Set to zero to return at the current height.
The default returned height is 15 meters (1500)
RTL_ALT_FINAL: In the final stage of the return flight or after completing a mission, the aircraft will reach the altitude.
Set to zero and the aircraft will land automatically.
RTL_LOIT_TIME: The time in milliseconds to hover above the “home” point before the final descent.
The hover time can be adjusted from 0 to 60,000 milliseconds.
WP_YAW_BEHAVIOR: Sets how the autopilot controls the “Yaw” during missions and homecoming “.
0 = Never change Yaw.
1 = The nose is facing the next waypoint or, for return, the nose is facing the “home” point.
2 = The nose is facing away from the next waypoint, or for return, the nose is facing away from the “home” point.
LAND_SPEED: The rate of descent during the final landing phase, in centimeters per second.
The landing speed is adjustable from 20 to 200 centimeters per second.
Other navigation settings also affect the RTL mode:
WPNAV_ACCEL
WPNAV_SPEED_DN
WPNAV_SPEED_UP
To use return, GPS positioning is required to establish a “home” point or take-off position before unlocking and taking off.
Landing and unlocking the aircraft again will reset the “home” point, which is a great feature when flying in the field.
If you get a fix for the first time while in flight, the “home” point is set to the position at the time of fix.
If the RTL_ALT is set to a number other than 0, it will reach and maintain this height on return.
Return uses WPNAV_SPEED to determine how fast to return.
Once the aircraft reaches the ‘home’ point, it will first enter hover mode and then land.
To stop the automatic landing, simply use the control switch to change the mode and clear the landing timing, and you can resume normal flight.
If you do not know the above parameters, please do not modify the corresponding parameters to avoid risks. If you do not understand and want to modify the corresponding parameters, please contact technical support or relevant professionals.
3.3 Fail-safe Return to Home
After triggering the radio fail-safe protection, the drone will perform the previously set operation; such as no operation, immediate landing, RTL or SmartRTL (Return/Smart Return). It can also be configured as an automatic route to bypass the fault protection and continue the route, or continue the landing if it is already in the landing phase.
If the multicopter is already locked, no failsafe is performed.
If the multicopter has unlocked but landed, it will lock immediately.
If the multi-rotor is unlocked in stabilize or Acro mode, and the throttle output value is
minimum, the drone will be locked.
Note: The UniDrone E900 remains in its fail-safe mode if the fail-safe clears (I. e. the remote controller transmitter and receiver re-establish communication). It does not automatically return to the flight mode that was active before the failsafe was triggered. This means that, for example, if the drone is in Loiter when a fail-safe occurs and the flight mode automatically changes to RTL, the drone will remain RTL even if the transmitter and receiver reestablish communication. If the pilot wants to regain control in Loiter, he needs to switch modes through the remote controller transmitter and then return to Loiter.
Chapter 4 Compass Calibration
Note:
• Do not calibrate in areas with strong magnetic fields or near large pieces of metal, such as magnetic mines, parking lots, construction areas with underground reinforcement, etc.
• Do not carry ferromagnetic substances, such as mobile phones, with you during calibration.
- Click the Start button
- Lift the drone and rotate it in different directions so that each side (front, back, left, right, top and bottom) points down to the earth for a few seconds
- When the drone rotates, the green indicator bar should extend farther and farther to the right until the calibration is completed
- After successful completion, three prompts will sound, and the “Please restart the autopilot” window will appear. Switch to other interfaces and switch back to this interface to check the offset value obtained by calibration. If the offset value is green, it means good (the absolute value of each offset is <400); Yellow is acceptable (the absolute value of each offset is <600); Red is but not zero (there may be magnetic field interference)
- After the calibration is complete, you need to restart the autopilot.
Note: If the calibration fails: you will hear a fault tone, the green bar may be reset to the left, and the calibration routine may restart (depending on the ground station). If the compass cannot be calibrated after multiple attempts, Press the “Cancel” button and change the “Eligibility Level (fitness)” drop-down list to a more relaxed setting, and then try again. If the compass calibration still fails, you can find the compass that may have magnetic interference through the “Flight Data” status bar interface. The failure of compass calibration is generally caused by the interference of magnetic fields around a single compass or multiple compasses. You can analyze the data of the compass (mag)
marked in the above figure. Under normal circumstances, before the compass calibration is completed, the data of X, Y and Z do not exceed 700 (regardless of positive or negative), and the fluctuation does not exceed 20; if the above conditions are not met, there may be continuous/non-continuous magnetic field interference; you can adjust the installation position of the compass or remove the interference source.

Chapter 9 remote controllerler
9.1 Takeoff
1) Turn on the drone remote controller and place the remote controller antenna correctly.
2) Install the battery and confirm that the smart battery limit is open (smart battery short press and long press to turn on).
3) Toggle the UAV mode lever to switch the mode to Loitor mode after confirming that the flight mode is correct; Pull down the throttle lever to the lowest level, pull the direction lever to the far right, and wait for the UAV to unlock.
4) When the throttle lever is kept above the neutral position, the aircraft will take off at a vertical rising height. When the throttle lever is kept in the neutral position, the drone will maintain the height. At the same time, when the pitch and roll joystick is kept in the neutral position, the drone will hover in the air to maintain position.
5) If you need the airplane to perform a course task (the course task must be written before the flight), you can switch the flight mode to AUTO mode, and the airplane will automatically climb and perform the course task without manual intervention.
6) Fully automatic route operation:
After the route is uploaded, click the takeoff command to increase the airplane to the default altitude (10m).
Note: After the UAV is automatically unlocked and climbs to the specified altitude, the UAV will automatically execute the route task by clicking the AUTO button.
In fully automatic flight mode, no manual intervention is required for return and landing.
Introduction to 9.2 common flight modes
- Loiter (hover mode): Hover mode maintains the aircraft’s current altitude, position, and heading.
- ALT HOLD: In the Alt Hold mode, the aircraft maintains the same altitude and can operate pitch, roll and yaw. The Alt Hold mode is the basis for many modes, such as Loiter and Sport.
- Stabilize (Attitude Mode): The multi-rotor attitude mode, altitude and attitude are all controlled by the remote controller stick, and the attitude of the UAV needs to be controlled in real time (but the aircraft can maintain attitude balance when the stick is not shifted)
- PosHold (hover angle control mode):PosHold mode is similar to Loiter mode, maintaining the current altitude, position and heading. The difference is that the joystickof the PosHold mode directly controls the angle of deflection of the aircraft.
- Guided (guided mode): This mode uses the data transmission good ground station to guide the aircraft position in real time. Boot mode is not a basic mode and is formed by switching between several other modes. When the aircraft reaches the target point, it will hover over the target point.

10.6 standard charge and discharge
10.6.1 Charging
- Charging current: The charging current shall not exceed the maximum charging current specified in this standard. Charging with a current higher than the recommend value may cause problems in the charge and discharge performance, mechanical properties, and safety of the battery, and may cause heat generation or leakage.
- Charging voltage: The charging voltage shall not exceed the rated voltage of 53.4V(Cell 4.45V) specified in this standard. Cell 4.5V is the maximum charging voltage limit. The charger shall be designed to meet this condition: when the cell voltage is higher than the rated voltage value, it may cause problems with the charging and discharging performance, mechanical performance and safety performance of the battery, which may lead to heat generation or leakage.
- Charging temperature
| Charging temperature | 5~15 ℃ | ≤(0.2C) |
| 15~45 ℃ | ≤(1C) |
Note
Charging temperature: The battery must be charged at the specified current within the above ambient temperature range.
- Prohibit reverse charging: connect the positive and negative poles of the battery correctly, and reverse charging is strictly prohibited. If the positive and negative poles of the battery are reversed, the battery cannot be charged. At the same time, reverse charging will reduce the charge and discharge performance and safety of the battery, and will cause heat and leakage.
10.6.2 Discharge
Note
- Discharge current shall not exceed the maximum discharge current specified in this standard. Large current discharge will cause the battery capacity to decrease sharply and cause overheating.
- Discharge temperature: Discharge at too low or too high temperature or not within the specified current range may cause battery failure or other conditions.
| discharge temperature | (-20~0 ℃) | ≤ 0.2C |
| 0~10 ℃ | ≤ 0.5C | |
| 1 ℃ 0-45 | ≤ 57A(T1/T2 temperature does not exceed 80 ℃) | |
| 4 ℃ 5-60 | ≤ 0.5C |
Over-discharge: It should be noted that during the long-term non-use of the battery, it may be in some kind of over-discharge state with other self-discharge characteristics. In order to prevent the occurrence of discharge, the battery should be regularly charged to maintain its voltage between 45V(cell 3.75V) and 46.8V(cell 3.9V), over-discharge will lead to the loss of battery performance and battery function.
The charger shall have a device to prevent the battery from discharging below the cut-off voltage specified in this standard. In addition, the charger should also have a device to prevent repeated charging. The steps are as follows: the battery should be pre-charged with a small current (0.01C) for 15 to 30 minutes before fast charging, so that the voltage of (each) battery core reaches 3.0V Above, fast charging. The
pre-charge step may be implemented with a 1 timer. If the voltage of the (individual) battery has not risen above 3.0V within the specified time of pre-charging, the charger shall be able to stop the next fast charging and indicate that the battery is in an abnormal state.
