DJI Inspire 2 Review

DJI Inspire 2 Review

The DJI Inspire 1 was a huge advance for drone engineering. The integrated FPV transmission system could livestream in HD, the gimbal rotated 360 degrees and the 4k camera was a feature the drone industry had never seen implemented before. As new drone-specific cameras began to emerge (the Zenmuse lies here) the Inspire 1 became the machine for aerial photography. Now it has been replaced by the next generation of Inspires: the DJI Inspire 2.

As a whole, the DJI Inspire 2 greatly modifies and improves the design of its predecessor. Everything from its camera capabilities, intelligent flight systems, dual-batteries (for much longer flying), self-heating technology (for colder climates), and more. Perhaps the most impressive new feature of the Inspire 2 is the dual video transmission system. We’ll go into detail about all of this further on – but with the implementation of the dual camera system – now the Inspire 2 can livestream FPV from two separate cameras independently. This greatly impacts the camera operator-pilot relationship, as now one can control the drone while the other simultaneously operates the camera; and each has his own vision.

In terms of the aircraft’s general configuration, it comes with vision sensing and a 2-axis FPV camera. It has carbon fiber arms and a magnesium aluminum composite shell. It can hit a top speed of 58mph with 2kg thrust per rotor and 15” props. The machine flies for just under thirty minutes.

To delve a bit more into the imaging system (arguably the most impressive part about the Inspire 2), it’s capable of capturing and storing 5.2k CinemaDNG and Apple ProRes video. It has H.265 and H.264 video support with 4k video at 100Mbps. The footage simultaneously records on the DJI CINESSD and a Micro-SD card. With the all new integrated CineCore 2.0 image processing system it can record with whatever camera is attached to the gimbal. A little note here: currently it’s compatible with the Zenmuse X4S and X5S.

In terms of the controller – it has a new and improved range of 4.3mi. The frequencies switch between 2.4 GHz and 5.8 GHz, using Lightbridge technology to stream FPV. With master-slave mode (integrated in the remote), multiple slave controllers are supported. It has an extension, HDMI, and USB port. With integrated technology, the controllers implement a new wireless HD image transmission system which means you can transmit between slave and master controller at distances up to 100m.

With the broadcast mode, it is now possible to broadcast directly from the Inspire 2 using a 1080i50 and 720p60 signal. It’s even possible to aerially livestream directly to TV – all that’s necessary is for the remote to be connected to a satellite truck.

Integrated Flight Systems

Sense & Avoid: Both forward and downward sensors allow for object detection for up to 30 meters. This protects flight at speeds up to 34mph with a controllable altitude angle of 25 degrees. The upward facing sensors can detect objects/obstacles at distances up to 16ft (greatly improving indoor flying). The sensors are constantly active regardless of which intelligent mode the drone is set to. The Sense & Avoid system serves as a backbone for the other intelligent systems which the Inspire 2 incorporates.

Spotlight Pro: As mentioned, Spotlight Pro is the intelligent mode that allows for the duality of both cameras (one taking principal photography and the other directing FPV to the pilot). It’s a tracking mode that enables solo pilots to capture angles, dynamics, and footage they’d otherwise never be able to do on their own. Incorporating advanced visual tracking algorithms, it locks onto the target object (specified by the pilot) and keeps the principal camera on it all times, despite what the drone itself is doing. It’s even smart enough to rotate the drone if the gimbal can’t make its full rotation to stay on whatever it’s tracking. This basically allows you to pilot while the drone is the camera-operator.

Within Spotlight Pro, there are two different shooting modes: Quick Mode and Composition Mode. In QM you set your target subject and the drone begins tracking. In Composition Mode you tap the desired subject and also set your tracking position. Then when the target begins to move, the drone will remain in this ‘set’ position (altitude and speed) and the gimbal will adjust to track the target.

Since it is integrated at the very heart of the Inspire 2’s tech guts, the Spotlight Pro intelligent system is available in all the other modes (ActiveTrack, TapFly, Waypoint and Point of Interest). To further this – all those intelligent systems are available (including Point of Interest, Waypoint, and QuickSpin). The Inspire 2 works to reduce the complexity of challenging shots and maneuvers, with the drone doing ‘most’ of the work.

Flight Performance

With the newly integrated propulsion system, the Inspire 2 optimizes flight performance up to 58mph, descending at 9m/s and climbing at 6m/s. With improved acceleration the Inspire 2 can go from 0 to 50mph in just five seconds. Both controllers have been optimized as well – increasing their sensitivity to make piloting the drone easier. Due to the increase of power in the machine, the Inspire 2 can now fly in harsher, heavier conditions. Its dual battery system allows for it to fly longer and its self-heating system stabilizes it in colder conditions.

Reliability

Overall, you can count on the Inspire 2 a lot more than on previous models. With newly implemented key modules (IMU and barometer), the DJI intelligent flight system will give accurate readings and data. The new sensors improve obstacle avoidance tremendously and the double batteries allow it to fly for longer (with the self-heating system sustaining it through harsher temperatures). This system has been tested for countless hours by DJI and has shown top performance and reliability (we’re taking their word for it here).

Overall

Overall the Inspire 2 (on paper) is a master of engineering and performance. Not only does it have one of the most intelligent flight systems to date (of all DJI models) but it also comes equipped with a powerhouse of a camera that can shoot in 5.2k CinemaDNG and Apple ProRes. With the new flight modes and autonomous features, this drone not only ‘flies itself’ but it can also act as your future camera operator. It has taken everything we loved so much about the Inspire 1 and greatly improved it. It’s truly a marvel of drone engineering with a spectacular camera. Of course we haven’t tested it yet, but we’re expecting big things. We’re hoping it lives up to DJI’s alpha engineering. We’re counting on it.
