- Folds into compact bundle
- Simple to fly
- Object avoidance
- Some jittery video
- Greater than Mavic Air
The GDU O2 is an easy-to-carry drone that takes 4K video, however we want the standard that comes from the smaller and sleeker DJI Mavic Air.
Everybody’s enjoying the moveable drone sport in this day and age. Impressed through the good fortune of the DJI Mavic fashions, there may be now an abundance of drones that fold up for compact garage, then fold out for flight. The O2 is GDU’s take in this idea; it is a compact drone that is identical in measurement to the Mavic Air, and will take 4K video. It is usually $60 not up to the Mavic Air, however with that bargain comes a couple of minor compromises.
Design: Compact and Handy
Essentially the most attention-grabbing a part of the O2’s design is the way you retailer it: The drone and controller clip in combination into one bundle of about 7.Three x four x Three.7 inches. That is just a little larger than the Mavic Air when folded up (6.6 x Three.2 x 2 inches), however the Mavic’s controller must be saved one by one.
When you wish to have to fly, the O2’s controller pulls out from the bottom of the bundle. Then you definitely fold out the antennas, and slide out the 2 aspects of the controller to deal with your smartphone (as much as 6 inches of display screen measurement) into the middle. The telephone connects to the controller over a USB connection: adapters for iPhone, USB-C and mini USB are incorporated, so maximum telephones will have to be usable. I discovered that my Samsung Be aware eight was once a good are compatible, and simplest slid into the middle of the far flung after I got rid of the skinny case I take advantage of.
The fingers of the drone slide out not like the folding fingers of the Mavic, however the fingers and locking mechanism really feel tough. The O2 measures 14.five inches from rotor tip to tip when deployed for flight. At the entrance of the drone is a small digicam, fastened on a small Three-axis stabilizer. Above this are two small cameras that the drone makes use of to come across stumbling blocks through measuring the adaptation between the 2 pictures.

It is a neat design that makes the O2 really easy to hold and retailer. There are a few problems, although: The gimbal and digicam lens are slightly fragile, and the transparent plastic duvet that protects the gimbal and digicam when no longer in use is awkward to slot in position and may simply turn out to be dislodged. Mix this with the comfortable pouch that GDU ships with the O2 (slightly than a troublesome case), and it’s good to have a broken digicam just a little too simply. Two spare units of rotor blades are incorporated, however be aware that you wish to have a screwdriver to interchange the blades.
Controller: Simply Insert Telephone
If you squeeze your smartphone into the controller, the display screen is nestled between your palms, making it smooth to view. In addition to the 2 flight sticks, there are a number of buttons and dials that assist you to keep watch over such options as auto takeoff, go back to house, recreation mode, digicam attitude and video recording. All of those relaxation conveniently below the fingertips, and the far flung comes with stickers that display what they do. That makes the training curve a lot much less steep than different controllers’ bewildering number of buttons.
The controller works along the unfastened GDU Mini app this is to be had for iOS and Android. It’s beautiful easy to make use of, offering a preview of the video from the digicam and get admission to to the extra in-depth settings of the drone. We did to find some problems right here, although:The video preview infrequently glitched out, even if the drone was once at shut vary. It additionally produced some slightly poorly translated error messages such because the absurd “Unusual extraordinary.”
Flight Efficiency: Zoomy
The O2 is a amusing drone to fly, with a lot of energy and maneuverability on be offering. We discovered it to be fast and responsive, reacting neatly to the controls and closing directly and degree, even if maneuvering at velocity. For a drone designed basically for taking pictures video, that is vital.
Commencing is straightforward: simply unpack the drone, flip it on and cling down the take-off button at the far flung. This begins the motors and units the drone flying, soaring about 6 toes above the bottom. Touchdown could also be smooth: The Go back To House (RTH) button units the drone to soaring about 30 toes above the bottom on the identical level it took off from, then lowers it down till it gently lands.
There also are a lot of computerized flight modes on be offering, with a excellent vary of preprogrammed strikes that create memorable movies. Those come with a slightly same old number of orbit pictures and monitoring pictures, however we in particular just like the rocket mode, the place the digicam tracks a decided on level with the digicam whilst flying upward at prime velocity to provide the impact of a rocket starting off. In addition to those, the O2 can navigate a chain of GPS-tracked waypoints to practice an outlined route.
The drone makes use of two cameras on its entrance to come across and keep away from stumbling blocks. We discovered this to be reasonably efficient: It simply swerved round bushes, partitions and other folks, however did not sense some smaller stumbling blocks like low-hanging leaves and small branches. It additionally does not come across items to the facet or at the back of the drone, however it’s efficient sufficient that it’s good to use it to practice you via a wooded house with out being worried an excessive amount of that the drone may hit a tree. Alternatively, the machine does not appear responsive sufficient to keep away from stumbling blocks when the drone is shifting quicker than strolling velocity. An extra digicam and ultrasonic sensor at the base of the drone permits it to come across the bottom and land softly.

The rate is upped rather while you turn the transfer at the controller to interact the game mode. GDU claims a most sensible velocity of simply over 33 mph, and I would not dispute this: it may give it some critical zooms while you give it room to fly. Recreation mode turns off the collision detection and one of the vital smoothing that helps to keep the digicam secure, so that you will have to use it simplest after you get aware of the way it flies within the commonplace mode. The game mode without a doubt pushes the envelope, and does require some warning in use. As soon as, I took a good flip when flying at low altitude and the drone slipped sideways, misplaced altitude, were given tangled in grass and crashed. Quadcopter drones all the time lose altitude once they maneuver, however the controller both limits the maneuver or will increase the thrust to compensate and stay the drone up. That does not occur in recreation mode.
Video and Photograph High quality
We discovered that the video captured through the O2 was once of fine high quality, however no longer with out some problems. Even though the video captured at 4K (3840 through 2160) solution at a velocity of 30 frames according to 2nd is sharp and transparent, there’s a distinct shaky glance to the video on the backside of the body. This appears to be brought about through the digicam vibrating somewhat, as it’s particularly noticeable when the drone is shifting or turning. Now we have asked a 2nd drone from GDU, and can replace this evaluate after we’ve had an opportunity to look if this factor recurs.
GDU O2 Drone Video Pattern
Video captured on the decrease full-HD solution (1920 through 1280 pixels) was once additionally somewhat disappointing, exhibiting a slightly comfortable and fuzzy glance, with blown-out highlights and a loss of element. Each resolutions additionally had a small, however noticeable, quantity of noise in them that was once in particular visual in low gentle.
GDU O2 Drone Video Pattern 2
The captured video is saved within the drone, which has 16GB of integrated reminiscence (there is not any detachable garage). That is sufficient for roughly 25 mins of 4K video, or sufficient to document greater than a unmarried battery’s price of flight. A top rate type (the O2 Plus) is to be had that incorporates 32GB of reminiscence, however the cost in this type is not set but.
The O2 is powered through a 4000 mAh battery that clips onto the again of the drone frame, and offers between 16 and 18 mins of flight, relying on how aggressively you fly. That is a smidge shorter than the Mavic Air’s 20-minute flight time, however it’s lengthy sufficient to fly round and seize a couple of mins of video conveniently with no need to speed your self.
When the battery reaches about 20 %, the far flung will beep and the drone will attempt to fly again to the takeoff level. In the event you override this and the battery reaches five according to cent, the O2 will ultimately surrender on you and mechanically land anywhere it’s.

The O2 comes with just one battery (spares are to be had for roughly $80). The incorporated charger can rate a unmarried flight battery at a time, taking about 45 mins to completely rate. The similar charger additionally juices up the controller.
It’s beautiful evident that the GDU O2 was once designed to enchantment to the similar person because the DJI Mavic Professional and the Mavic Air: those that need high quality aerial video in a compact, moveable bundle. And the O2 without a doubt succeeds on this as it is extremely moveable and fast to deploy for flight. It’s easy to fly as neatly, offering comfortable-to-use controls and a whole lot of flight and capturing modes.
So, it’s a difficult pick out between the O2 and the Mavic Air. The O2 has a extra joyful controller and is more economical (and the cost distinction is sufficient to shop for a spare battery), however the chunky, business design of the O2 isn’t as interesting as the graceful curves of the Mavic Air. And, extra vital, the video high quality of the O2 isn’t reasonably as easy because the Mavic. The O2 is excellent, however the Mavic Air is best.
