DJI Phantom 4 Quadcopter Drone

• In P Mode, Forward Obstacle Sensing System, Vision Positioning System, and GPS are activated. Intelligent Flight Modes, ActiveTrack and TapFly are also accessed in this mode. 
• In S Mode, the Phantom 4 flies at higher speeds with satellite and Vision Positioning support, but Forward Obstacle Sensing Systems are switched off 
• In A Mode, Forward Obstacle Sensing Systems, satellite and Vision Positioning systems are switched off. An internal barometer is used to maintain altitude.

1. If you want to follow a person but the person icon does not appear when you select them, manually identify them by dragging a box around them. 
2. The Phantom 4 builds a 3D model of the subject in ActiveTrack Mode to improve following accuracy. To help it learn, fly it around the object before following. 
3. The subject should be in the middle of the screen when selected to avoid partial recognition. 
4. The subject should be contrasted with the background to enable recognition. Light levels should be neither too low (at night) nor too high (in a snowfield with bright sunshine). 
5. The subject should not move too quickly. Gentle acceleration and top speeds below 22mph (36kph) are recommended. 
6. If the subject changes size or shape, such as if a person crouches down, the aircraft might lose track. 
7. The subject should be on the ground. To avoid accidents, do not command your aircraft to follow another aircraft. Rapid altitude changes of the subject should be avoided.

1. Pitch - Changes the distance from the followed object. 
2. Roll - The aircraft flies around the followed object. 
3. Throttle - Altitude will change. 
4. Orientation - No apparent reaction.

1. The point you selected will determine the flight path. If you selected a point in the sky, the aircraft will fly in that direction until it reaches its maximum altitude. If TapFly is not stopped, the aircraft will fly until remote controller signal and video downlink are lost, triggering Return to Home. The pilot can press the STOP button in DJI GO, the Pause button on the remote controller, or switch modes on the remote controller, or pull back fully on the right control stick to stop TapFly. 
2. If a point selected is on the ground, the aircraft will fly straight to the point and will level off 4.8m above the ground. If another TapFly command to the ground is executed, the aircraft will descend to 0.8m and level off. 
3. DO NOT use TapFly to fly towards people or animals.

1. P Mode 11mph (18kph)/7mph (11kph)/ 22mph (36kph) 
2. S Mode 13mph (27kph)/9mph (14.4kph)/45mph (72kph) 
3. A Mode 11mph (18kph) 7mph (11kph)/36mph (58kph)

There are three icons on the left of the camera interface. Click the remote controller icon and four modes will appear: TapFly, ActiveTrack, Normal and Intelligent IOC (equivalent to F Mode on the Phantom 3).

In ActiveTrack Mode, the aircraft follows a moving person or object. To follow a person, tap them on your smart device screen. The aircraft will automatically put a green box around them. You will see a human icon in the top-left corner of the screen and a GO button on the right. Press Go to begin tracking. If the aircraft is unable to identify the subject, drag a box around them.

Place the camera at or below a 25 degree angle then select a point in the distance and press GO. The aircraft will turn to the destination and then fly there in a straight line. You can adjust the speed from 2mph (4kph) to 22mph (36kph) on the right side of the app. The maximum speed is 22mph (36kph) as slower speeds are required to navigate around complex obstacles.

Yes, your drone must not be flown within any restricted airspace. For details of restricted airspaces, please see this interactive map.

No, anyone can fly a drone for fun. You only need a license if you're using a drone for a commercial/business purpose. You do, however, need to be familiar with the law before you fly one. For more information click here
