Accessories
Companies like FreeWell and PolarPro have made accessories for the Mavic Air, but We Talk UAV was unable to find any accessories or even extra batteries for the GDU o2. The lack of third-party support for the GDU o2 gave an extra point towards the Mavic Air.
Settings
After GDU o2 was reviewed in another video, the drone’s biggest drawback was its inability to change the camera settings. Since the frame rate, shutter speed and ISO are locked on the o2, one more point went towards the Mavic Air.
Video quality
Even though both drones are made to shoot videos up to 4K, the Mavic Air’s video quality is better since the settings can be changed. The lack of ND filters for the GDU o2 also means the final footage is prone to Jello-effect.
Range
Both portable drones are rated to fly out about 0.62 miles, so they both tied in the range category.
Storage
Mavic Air is the first DJI consumer drone built with internal memory, but GDU o2 also has internal memory. GDU has 16 GB of internal storage, whereas Mavic Air only has 8 GB. Even though GDU o2 has more storage, Mavic Air has a microSD slot. GDU o2’s lack of external memory support means it is limited to only 16 GB.
Sensor size
Mavic Air has a 1 /2.3” 12-megapixel CMOS sensor, whereas GDU o2 has a 1/3” 13-megapixel sensor. Mavic Air gained one more point because of a slightly larger sensor.
Noise
Overall, GDU o2’s flight noise was louder.
Hovering
Mavic Air proved to be more stable when hovering in place.
