1. Changing the position of the Phantom 4 LED lights (mandatory)

 

Changing the position of the LED lights on the DJI Phantom 4, 4 Advanced, and 4 Pro can be performed by the customer.

(1) The reason to change the position of the LED lights on the Phantom 4, 4 Advanced, and 4 Pro

1. The LED lights on the Phantom 4, 4 Advanced, and 4 Pro are located under each motor.


 
2. However, the spherical guard for the DJI Phantom 4 must be fixed onto the T connecting shafts under each motor in order to be installed on the Phantom 4, 4 Advanced or 4 Pro.


 
3. Consequently, the LED lights must be moved to the center of the arms.


 
4. The LED lights will shine light from here.


 

(2) Instructions to change the LED light positions (mandatory)

 
1. Click here for “Detailed Instructions to Change LED Light Positions.” The person in charge of changing the position of the LED lights must read these instructions.
 
2. Watching the below video will also help you understand the instructions.


 
3. First, remove the LED light upwards with a flathead screwdriver,


 
4. move it to the shown position, and fix with insulation tape. Process is completed after you close the top lid.


 

2 Attaching the Spherical Connection Shaft to the Phantom 4 Main Body

 
(1) As shown in the picture below, attach and fix the spherical connection shaft (black T shaped parts to the left and right) to the DJI Phantom 4, 4 Advance, or 4 Pro (referred to simply as Phantom 4 below).


 
(2) On the Phantom 4 there are three screws for fixing the motors located under each motor (back side). Remove these screws and fix the screws included with the spherical connection shaft instead.


 
(3) The below shows how it should look from the back side.


 
(4) Specifically, fix the Phantom 4’s two left motors to the spherical connection shaft with the label that reads “←forward direction to the left” using the included screws. The Phantom 4’s two left motors are the two motors the can be seen on the left when you look at the Phantom 4 from behind and lift it as is above your head.


 
(5) Similarly, fix the Phantom 4’s two right motors to the spherical connection axis with the label that reads “←forward direction to the right” using the included screws.
 

3 Assembly of the sphere

(2) The opening on the top of the sphere
The opening on top of the sphere needs to be removed, so absolutely do not apply instant adhesive.
 
Note: If the black carbon rod on the sphere opening is removed many tens of times, it is possible that the insertion section will become loose and the carbon rod will easily slip out. This is dangerous during flight. If this happens, apply instant adhesive to the carbon rod along the 4 mm section of the tip to make it thicker. This will prevent it from slipping. However, do not insert the carbon rod into the blue joint until the instant adhesive has dried.
 

4 Performance

 
(1) The only part on the spherical guard that can be removed is the opening for the Phantom 4. All other sections of the spherical guard are glued together and cannot be made into a hemisphere.
 
(2) The maximum combined thrust (lifting power) of the 4 DJI Phantom 4 motors is approx. 3,200 g. This is sufficient power to lift the 2,000 g gross weight of the PAUI Rotating Spherical Drone Guard 5 for Phantom 4, allowing it to fly stably. However, flight time will be affected. →(3)
 

(3) [Very important] Flight time is approx. 15 minutes. Keep an eye on the remaining battery level on the monitor and promptly land the drone once the warning message appears.

 

(4) [Very important] Be sure to perform either ① or ② below in order to disable the vision system on the Phantom 4, 4 Advanced and the vision system and infrared detection system on the Phantom 4 Pro.
1 Disable the vision system and fly in S (sports) mode.
2 Disable the vision system and fly in A (Atti) mode.
If the vision system or infrared detection system are activated, the Phantom 4 (4 Advance,d 4 Pro) will detect the sphere and will not operate.

If the Phantom 4 Pro vision system and/or infrared detection system mistakes the rotating spherical guard for the ground it can run out of control, as the below video shows.
 

 

5 Flight Procedure

 
(1) Make sure the transmitter power, DJI Phantom 4 main unit power, and DJI GO 4 app are on.
 

(2) [Very important] Disable the ① vision system on the Phantom 4, 4 Advanced, Phantom 4 Pro on the transmitter, and set to S (Sports) mode. Or, disable the ② vision system and set to A (Atti) mode.

 

(3) [Very important] Perform compass calibration 360 degrees horizontally and 360 degrees vertically.

* Make sure to perform every time you exchange the batteries. Failing to do so may make it impossible to control the drone.

* If there is battery life remaining after the first flight, perform the second flight as below.

1 If the motor is still on after the first flight (if the propellers are still rotating), there is no need to perform compass calibration; the drone will fly stably during the second flight.

2 In contrast, if the motor is stopped (if the propellers are stopped) after the first flight, the drone will not fly stably during the second flight. In this situation, it is required that you perform the compass calibration and as in (4) below work on the drone on a flat surface (when the motor stops the main controller (MC) will judge that the drone has landed on a flat surface. However, the drone will actually be moving diagonally inside of the sphere. The MC will then be unable to detect that the drone has landed on a flat surface, causing it to be unstable for the second flight).
 
(4) Place the Phantom 4 on a flat surface, and wait until it receives a GPS signal.

*By placing the drone on a flat surface, the main controller will remember at which position it is parallel to flat ground. If the main controller has forgotten this, it may be impossible to control the drone.
 
(5) Insert and set the Phantom 4 into the spherical guard. Please refer to the below.


 

(6) [Very important] Manual take off

Push the two proportional control system sticks to the front and inwards to start the engine, and perform take off by gradually raising the elevation stick. Do not use the automatic take off function on the DJI GO 4 app. Using the automatic take off will cause the app to think that the motor output has been overloaded, due to the fact that the drone is heavier than normal, causing the motor overload warning to show on the app. After that, an over discharge warning may appear.
 

(7) [Very important] Manual soft landing

*Please perform soft landings so as not to inflict excess impact on the rotating spherical guard. Specifically, momentarily stop descent at 10 – 20 cm off the ground, and then land the drone slowly. Do not use the automatic landing function on the DJI GO 4 app. Be careful when landing on concrete in particular.
 
(8) Remove the drone from the rotating spherical guard
 

that’s all.
