The unmanned helicopter is a small UAV co-developed with the Harbin Institute of Technology (HIT) and Hong Kong University of Science and Technology (HKUST). It is intended for high-elevation missions and can operate up to a wind scale of 6. The general designer is Lǐ Zé-Xiāng (李泽湘), and the chief designer for software is Zhū Xiǎo-Ruǐ (朱晓蕊) from HIT.
The Spark is an affordable consumer drone designed for people who want a cheaper entry into the camera drone ecosystem. Its defining feature is the reliance on gesture control in addition to a remote control.
The Osmo (灵眸) is a camcorder developed by DJI. The camera uses a smartphone to view camera footage and can record 4K and take either 12-16MP stills. The camera is interchangeable, with the Zenmuse X3, X3 Zoom, X5, and X5R gimbals compatible, and uses the FM-15 Flexi microphone.
Similar to the Osmo, it instead relies on the user's smartphone as the camera. Most smartphones are accepted into the gimbal with a width range of 2.31-3.34 inch (58.6-84.8 mm).
The DJI Goggles  are comfortable goggles designed for seamless FPV flying with DJI products. They combine a pair of large ultra-high quality screens, long-range, low lag wireless connectivity, and direct control of photo and video capture. With Intelligent Flight Modes like ActiveTrack, TapFly, Terrain Follow, Cinematic Mode and Tripod mode, a totally new flying dimension is created.
DJI Goggles are able to offer both 720p/60fps and close range 1080p/30fps viewing with an extremely low latency of just 110ms. Through DJI’s OcuSync wireless transmission system, up to four devices can be connected to the Mavic Pro simultaneously. Antennas built into the headband ensure 360° of coverage, offering a reliable connection even if the aircraft is flying behind you. Share the fun of immersive flying with friends by giving them a bird’s eye view of the world as you pilot their experience.
Typical “2K” screens inside the goggles are split into two 1280x1440 sections, one for each eye. When viewing a 16:9 image, some sections are further cut off, leaving only a quarter of the available pixels. DJI Goggles have two 1920x1080 screens providing more than twice the amount of pixels of a typical 2K single screen.
DJI Goggles are a perfect pair with DJI's new Intelligent Flight Mode: Fixed-Wing Mode. In this mode, the aircraft doesn’t turn left or right but instead flies forward with enough rotational movement for realistic flight simulation. Combined with Head Tracking Mode, you can use your head to control the Mavic Pro for a fully realized flight experience. An AR trajectory prediction feature in Fixed-Wing Mode makes using this mode in complex environments safer. Other Intelligent Flight Modes include Terrain Follow, ActiveTrack, TapFly, Cinematic Mode and Tripod Mode.
