Pros Cons
Attractive design Shoots steady, sharp video.
Easy to fly ———–
Fast and maneuverable ———-

The Solo is the newest drone from 3D Robotics, which makes its software accessible for download, ready for hacking or rewriting. But even if you’re not a tinkerer, you’re likely to take pleasure in flying the Solo. It is easy to control, but powerful. The corporation packs in a lot of features for its airborne movie maker, but you’ll require purchasing a few add-ons to take full benefits.

Editor’s Note (1/26/17): 3D Robotics is no longer selling a customer version of the 3DR Solo, but will carry on to support the purchaser model for the predictable future, and is still providing a one-year hardware warranty.

An inclusive kit includes the Solo drone, the gimbal accessory, and a GoPro action camera. That makes it more involved than the DJI Phantom 3 Standard, which offers comparable specs without requiring any add-ons. on the other hand, Solo’s software is more developed and is easier to use, and there is more opportunity for growth, through both software and hardware. That might tip the balance for pros, and those who want to experiment with accurately autonomous drones.

Design of 3DR Solo Drone

Minimal is the word that springs to mind when you see the Solo. It’s an angular bump of matte black plastic that would look perfect hovering over the lifeless body of John Connor on the set of a Terminator movie. A large 5,200mAh battery attaches on top of that smooth body, right next to the power button.

The quadcopter is comparatively large at just under 19 inches from tip to tip, and heavy: with the battery, gimbal and camera installed, it weighs in at a hefty 3.35 pounds. That means it needs to be registered with the FAA, as it is over the 0.5 pounds minimum weight.

Once you turn the Solo on, the quadcopter gets a bit more colorful, as bright multicolor LEDs under each motor display the status. These are simply observable in daylight and are rather bright at night. In flying mode, red indicates the front of the quadcopter and blue the back.

On the bottom sits an accessory connector as well as a number of much smaller LEDs presentation the status of the device while it is starting up. These lights flicker while the drone is starting and connecting, and the speed of these blinks can be used to detect a problem if something fails. At present, while no accessible devices use the connector port, 3DR is hoping developers will make such accessories through the company’s Made for Solo program.

At the frontage of the base is the camera holder, which fits a GoPro Hero. In the standard model, this is a simple frame that holds the camera in place, but 3DR also offers an active gimbal that can pan, tilt and rotate the camera. A cable connects to the gimbal from the guts of the drone, which allows you to manage both the camera and the gimbal itself. For the standard or the gimbal mount, an HDMI cable plugs into the camera, feeding a live preview back to the smartphone app that controls the drone. We tested both the normal camera holder and the $380 3-axis gimbal while using a GoPro 3+ Silver.

Controller

The controller that comes with the Solo is a likewise styled lump of black matte plastic, with a glossy plastic top. It is replete with eight buttons and dials, as well as the two control sticks and a small OLED display in the middle. This display doesn’t show the live video from the drone. Instead, it shows the status of the drone, representing things like the battery life, the number of GPS satellites it can see and flight mode.

The controller fits well in my hand, with two ridges on the back providing a firm grip. The thumbs obviously fall onto the control sticks, but I could still reach above the other buttons. The index fingers on both hands can also reach the shoulder controls for the gimbal. The left control tilts the camera up and down manually, while the right shoulder controls make active the automatic pan and tilt control.

The live-video preview shows up on a Smartphone running the free 3DR Solo app, obtainable for iOS and Android. This Smartphone fits into a holder attached to the top of the remote control that’s modifiable for different device sizes. This holds onto a smartphone tightly but doesn’t work well with anything larger than a smartphone with a 5-inch screen. I tried it with an iPad Air, and whereas the tablet did fit into the holder, it made the regulator unbalanced: it felt like it was always about to tip forward and slip out of my hands. The Nexus 5 phone worked much better.

The app shows the video preview with some information and controls overlaid on it, including altitude, heading, signal strength and the controls for the camera. If you are using a GoPro Hero 4, you can also control the camera from the app, shifting the shooting mode and tweaking the settings for the best image quality from the app itself. Older GoPros can still be used, but you can’t control the settings on the fly.

Flying

The Solo is an uncomplicated drone to fly, with automated takeoff and landing. To take off, you let the drone sit for a minute after you turn it on (to obtain a GPS signal), then press the fly button. This starts the motors. Press the fly button once more, and the Solo will take off and hover about 4 feet off the ground. The manager sticks are very quick to respond to subtle movements and small changes.

The Solo offers a plethora of flight modes: four videos and five advanced flight. The video modes are designed for capturing specific video shots. Cable Cam creates a virtual flight path between two or multiple user-defined points, allowing the camera to pan and tilt as it flies. This makes it easy to make flyby shots at the speed you set. Orbit mode puts the drone into a circular orbit around a chosen point, keeping the camera pointed toward the center. Follow mode sets the drone to follow the controller, remaining at a preset altitude and distance.

These modes work exceedingly well and are more automated than the similar modes of the DJI Phantom 3. On the Phantom 3, the pilot controls the speed of the drone with one of the control sticks when in a flight mode, but the Solo automates that. For example, if you set up a Cable Cam shot, but the quadcopter goes too speedy, you don’t have to reconstruct the entire path; instead, you just change the speed slider, and the drone recalculates the path. In Orbit mode, if you make a decision you want the circle to be a little bit larger, just drag the radius of the path on the on-screen map and the Solo recalculates the path. The same thing applies to the speed of the orbit.

It’s rather like having a co-pilot: You can focus on the video while your co-pilot keeps an eye on the details that make it occur. You do need to make use of some caution, of course: The drone won’t notice if it is about to fly into a tree when you widen the radius of an orbit shot (something the DJI Phantom 4 won’t have to worry about, thanks to its object avoidance technology). luckily, there is a pause button on the controller — hit this in any flight mode and the Solo will stop and hover in place.

Enabling the advanced modes setting in the Solo app unlocks several new flight modes designed for acrobatic use: Fly: Manual, Stabilize, Drift, Acro, and Sport. Fly: Manual turns the Solo into a fully manual quadcopter: the pilot has complete control, and there is no adjustment for wind or the altitude. Stabilize is similar, except for when you release the control sticks, the quadcopter will try to hover in place.

Drift amusingly makes the quadcopter fly more like an RC plane. Acro entirely removes the limits on the orientation of the quadcopter, making it probable to roll and flip over. Finally, Sport mode behaves like Acro mode but overrides the pilot if it comes too close to the ground. These modes are great fun to fly in but do need some skills or you may risk a costly crash.

Autonomous Flying

As you may have guessed from some of the modes, the Solo is built for autonomous flying, unlike a lot of drones. Much of the processing power that helps it fly is built into the drone itself, rather than the controller or the phone. For example, you can place the drone to Orbit, then put the controller down and do something else as it films and circles.

The free Android (not on iOS yet) Tower app takes this a slight further. In this regulator app, you can select an area on a map you want to survey, and the app automatically creates a flight plan, feeds it to the drone and off it goes. For experts who want to make use of a drone for such jobs as surveying an area, creating 3D models or monitoring construction, this is a very helpful app. 3DR also offers a very inclusive software development kit (SDK) called DroneKit that allows advanced users to write their own app. Although DJI offers a similar program, the 3DR one offers further access to the drone’s innards itself.

Photos & Video

The Solo cannot take photos and video without an added device. Instead, it works with a GoPro camera, which connects to a control cable and an HDMI cable that feeds the video back to the drone and the controlling app. This permits the Solo to control the GoPro 4 and change settings. The older GoPro Hero 3 doesn’t get a similar level of control, but the drone can still stop and start a video recording on the camera.

The combination worked very well, as I controlled both the drone and the GoPro from the remote, starting and stopping recording while flying as well as taking photos. The resolution and frame rate of these videos depends on the type of GoPro you make use of, but with a GoPro 4 Hero Black, I could shoot 4K video at 60 frames per second. GoPro 4 users also can control the resolution and frame rate of the video from the app.

To dock the camera you can make use of the standard holder, or you can purchase the not obligatory gimbal. The standard holder only faces the GoPro front or down at a fixed angle. The rubber grommets it uses cushioned the GoPro from some of the buffeting and vibration of the drone in flight, but there was still some understandable vibration, which manifested as slightly fuzzy video when the drone was maneuvering.

The gimbal mount includes a number of rubber isolators that prevent vibrations being transmitted to the camera, plus the motors that move the camera aggressively combat vibrations. This did a much better job, producing very smooth, clean video even through fairly violent maneuvers. The gimbal holds the camera steadily in place and allows the camera to go independently, pointing left or right and up and down. The video we shot was better to what we got with the DJI Phantom 3, as the Solo-shot footage showed none of the occasional glitches and vibrations that we saw from DJI’s drone.

The remote control also offers control over the gimbal, with a manual pan/tilt on the left shoulder paddle and an automatic pan/tilt on the right shoulder. You can preprogram the buttons to change to particular camera angles with a touch. The speed at which the camera moves can be controlled by the dial between the two buttons. This amalgamation allows you to create very smooth, the professional-looking camera moves, and even reproduce the same move on subsequent flights. That’s very helpful if you are doing a time-lapse or a before-and-after shot, or if you want to have multiple takes.

The open-source nature of the Solo also means that you are able to attach other cameras. Using a 3D-printed adapter, I mounted a Ricoh Theta S 360-degree camera in the position of the GoPro and shot 360-degree video from 150 feet up. This adapter would work for any camera with a tripod socket as it uses a standard tripod screw.

Reparability

The Solo is a very repairable drone: 3DR sells all of the parts, from rotor blades (about $15 for two) to the frame and legs of the quadcopter (about $99 for a kit that includes replacement frame and legs, or $15 for individual legs). New motors cost about $60. These are all simple to swap out and replace: the rotors are color-coded and basically screw into place. Other components are held in place by a few screws — just undo these, and the parts pop out for replacement.

We did find that some parts of the Solo are rather fragile, though. Most crashes we had broken the rotor blades, requiring replacements. After one bad crash, the frame of the quadcopter cracked when the drone hit the ground, requiring us to replace the entire frame. This didn’t ask price too much (we used a crash repair kit that included a new case and new legs for $70), but it was a very complex procedure. To replace the frame, I had to eliminate all of the electronics, cabling, and motors from the old case and replace them in the new one, a process that reminded me of brain surgery. the majority of repairs are covered in 3DR’s outstanding documentation, but this one wasn’t.

We also had difficulty with the recent 2.0 version of the 3DR Solo app. A failed update to the software on the drone and controller left the two unable to communicate, and we were incapable to restore them to the preceding version. 3DR sent us another drone to test and we didn’t have the problem again.

Battery Life

The Solo uses a big, heavy 5,200mAh Lithium Polymer battery that latches into the top of the drone. We timed an acceptable 22 minutes of flying time in our tests, which is quite average for this type of drone and is comparable to the DJI Phantom 3. The DJI Phantom 4 claims it will get 28 minutes, but we’ll have to wait to test that to confirm.

The Solo’s battery took a long 70 minutes to recharge. You can only charge one battery at a time, and unlike the DJI Phantom 3, there are no third-party chargers obtainable that can juice up multiple batteries. Extra batteries aren’t cheap: 3DR sells them for $149 each, and there are no third-party batteries available.

Bottom Line

The base price of the Solo bundle is now reasonably cheap at $400, but you’ll need to add your own GoPro to capture video, which will charge you between $100 and $400, depending on the model. That makes it about the same price as the DJI Phantom 3, which is self-contained.

But the Solo does have some advantages over its less-expensive rival. The controller and app are better than the rivalry, with a cleaner design and less cluttered interface. The Solo is a little easier to fly, with a further responsive remote and flight modes that are more automated and less puzzling to make use of. It also appeals more to hackers and tinkerers, thanks to its open-source plans that allow you to get deep into the guts of the drone. If you want a drone that you can pull out of the box and start shooting with, the Phantom 3 or the Parrot Bebop 2 are better bets. But if you want to perform further complex shooting and don’t mind a steeper learning curve, the 3DR Solo is the drone to get.

Conclusion

The 3DR Solo offers a lot of features in an easy-to-fly package that presses on drone smarts to the maximum value. We thoroughly tested the 3DR Solo Drone and get some results. 3DR Solo Drone is beneficial to use for both professionals and beginners. 3DR Solo Drone can be used for personal purposes. 3DR Solo Drone is simple to use.
