How to use VR PRO: FPV flight with DJI drone and VR gogglesVR PRO is an FPV pilot app for DJI drones developed by Michele Vagnetti. If you put your iPhone in a VR goggles on the market , you can experience it as if you were flying on a drone. You can try as many FPV flights as you like for 100 seconds per flight for free. The 100-second limit will be lifted with in-app purchase (7.99USD).

What you need for FPV flightTo experience FPV flight with VR PRO app, you need four things: the DJI drone that this app supports, iPhone, VR goggles on the market, and controller connection cable.
Supported drones , which are also listed on Official website , are DJI's Mavic 2 series, Mavic Pro series, Mavic Air, Mavic Mini, Spark, and Phantom 3/4 series. The Mavic Mini was supported in August 2020 and the Mavic Air 2 was supported in December.
VR goggles can be used with any VR 3D glasses for iPhone that are compatible with Google cardboard specifications. You can now buy Google cardboard compatible VR goggles made of cardboard cheaply as shown in the figure at toy shops. At first, I think it's a good idea to try something cheap like this.
Controller connection cable is used to connect iPhone in the VR goggles to DJI controller. The one that comes with drone is not long enough. It is necessary to purchase a commercially available cable of about 60 cm (2 ft.) separately.
Install VR PRO app
Quick startAnyway, let's experience FPV flight. Control using VR PRO app instead of DJI FLY app. Except for changing the app, you can follow the usual procedure.
Tap (VR goggle) icon at the bottom right to move to the control screen in VR mode. Tap “Tap to start” in the center to switch to Normal control mode .
Even if you move to the control screen, sometimes the camera image of the drone may not be displayed, or the last footage from the last flight may remain. In such a case, please close the VR PRO app from App switcher and restart the app.
VR mode control screenThis is a screen example for Mavic mini.
|1||Battery level of controller, iPhone and drone are displayed|
|2||Distance of the drone from controller (iPhone) is displayed|
|3||Speed of the drone is displayed|
|4||Shows altitude of the drone from takeoff location|
|5||If you have not made in-app purchases, remaining time in VR mode will be displayed|
|6||Enabled / disabled status of the vision system is displayed|
|7||Displays the signal strength between controller and drone|
Switching VR camera
By pressing the C2 button on the controller or pressing the video button and camera button at the same time (Mavic mini), you can switch between the image from the drone and the image taken by the iPhone camera. You can also maneuver from a ground perspective while wearing VR goggles. (Requires VR goggles that do not block the iPhone camera)
Head tracking can be turned on / off by briefly pressing the 5D button (Mavic pro), Fn button (Mavic Air and Spark), or RTH button (Mavic mini) on the controller. When head tracking is turned on, you can move the drone's camera (gimbal) up and down by moving the head wearing VR goggles up and down. With the Mavic 2, you can also swing the camera left and right.
You can switch the gimbal behavior to “Follow”or“FPV”. In Follow mode, the three axes are stabilized and the field of view is horizontal even while the drone is turning. On the other hand, in FPV mode, the roll axis is not stabilized and the field of view is tilted when turning.
To switch this, press and hold the 5D button (Mavic pro), Fn button (Mavic Air and Spark), or camera button (Mavic mini) on the controller for at least 2 seconds.
Note that only Spark can use head tracking and gimbal FPV mode at the same time.
Adjusting visibility of VR gogglesYou can adjust the view of VR goggle according to the shape of the VR goggle and your face and eyes.
Move the right stick left or right to widen / narrow the positions of the left and right images (adjust eye width).
Move the left stick up and down to change the size of the image.
Move the left stick to the right to save the current settings and exit “Adjustment Mode”.
If the iPhone screen is out of focus due to myopia or presbyopia, move the iPhone forward or backward in the VR goggles to bring it into focus. We recommend using VR goggles with position adjustment and focus adjustment functions.
Normal control modeIn the VR PRO app, you can also operate in Normal control mode without using VR goggles.

If you play the video shot with video playback software that can display subtitles such as VLC media player and select display subtitle, you can see that Shooting parameters, GPS location information, distance and height from home point, speed, etc. are recorded.
In addition, you can display the histogram, fix the gimbal during shooting, display the grid, check the capacity of the SD card, set the anti-flicker, reset the serial number of the file name, format the SD card, etc.

Three types of “position markers”can be displayed on top of the image from the drone.
A blue marker indicates the current position of the controller (iPhone).
A green marker indicates the home point, the first place the drone received a powerful satellite positioning system (GNSS) signal after power-on.
Point Of Interest(POI)
A red marker indicates the POI (where you are interested) and the distance to it. You can specify the places you care about before take off, such as the destination of flight or the target of shooting.
