DJI Phantom 4 Pro Review

Flight modes4.3mi (7km) long-range controlSensor redundancyIntelligent batteriesDJI GO 4Different productions require different flight characteristics, and the Phantom 4 Pro offers three modes for flight: P, A and S. Switching between them allows pilots to get the control they need, whether they seek smoothness, simplicity, intelligent navigation or speed. In Position Mode, TapFly, ActiveTrack, obstacle sensing and positioning features are available.

Sport Mode adds extra agility and higher speed, reaching 45 mph (72 kph). Atti Mode switches off satellite stabilization and holds the Phantom 4 Pro’s altitude. It is ideal for experienced pilots looking to capture smoother footage. Tripod Mode, which limits speed to 4mph (7kph) provides precision control for fine framing and indoor flying. Both the infrared sensing system and vision sensors are enabled in these modes for a safer flight experience.

Using brand new DJI Lightbridge HD video transmission technology, the Phantom 4 Pro has a maximum transmission range of 4.3i (7km)*. Before each flight, it scans a range of available frequencies to find and use the one with the least interference. By supporting 2.4GHz and 5.8 GHz frequency bands, it gives you more reliable control. Tightly integrated with DJI GO 4, Lightbridge video transmission also sends vital flight statistics in real time, and can be used to quickly download photos and videos to connected mobile devices.

The Lightbridge video transmission system uses advanced transmission technologies and can automatically adjust to environmental conditions. It ensures high quality, low latency image transmission across its range and offers pilots a better shooting experience. Traditional analog video transmission occupies a larger bandwidth and is more susceptible to interference. It also suffers from poor image quality and short range.

 Wi-Fi transmission also compares poorly, suffering from low latency, lengthy re-connection times, and short transmission distances due to the high cost of more powerful Wi-Fi transmission. * Unobstructed, free of interference, when FCC compliant.The Phantom 4 Pro features dual compass modules and dual IMU units, making it more reliable when compared to many helicopters and quadcopters.

 Compasses and IMUs are important sensors to ensure a stable flight and the Phantom 4 Pro constantly compares the data it receives through both pairs.

 This data is run through advanced algorithms to check accuracy and any inaccurate data is simply discarded without affecting flight, keeping flight steady and reliable.Professional aerial imaging benefits from longer flight times. The Phantom 4 Pro has a maximum flight time of 30 minutes, providing more time in the air to capture the perfect shot.

The DJI GO 4 app shows battery lifetime and calculates remaining flight times according to distance traveled and more. It will give alerts when it reaches a minimum safe amount required for a safe journey back to the takeoff point. An advanced battery management system is also in place to prevent overcharging and over draining. When placed in longer term storage, batteries will discharge power to maintain good health.When shooting aerials, the remote controller is responsible for most physical controls including piloting and capture. However, more challenging shoots require a real-time video feed, vital flight statistics and advanced settings.

 These are traditionally handled through a smart device, making the smart device essential to aerial imaging. The DJI GO 4 app is optimized for aerials and is updated along with the aircraft to ensure all features are supported. It can be used on smart devices and is available to be integrated into the DJI CrystalSky monitor, providing simple and convenient control.

 Using the DJI GO 4 app, a large number of Intelligent Flight Modes are available. It also provides access to full manual camera controls, including ISO, aperture, shutter speed, image formats, and more. Any changes in DJI GO 4 will appear almost instantly on-screen. Vital flight data and video transmission status are easy to check in-app, further enhancing control efficiency and convenience. DJI GO 4 includes editing features for quick editing and sharing to social media and even live streaming. After each flight, flight routes and data are automatically recorded and synchronized to the attached DJI GO 4 account, keeping it readily accessible for you to review. Both flight logs and data are easy to record and review.
