To gauge flight performance, we put the drone through a number of tests to see how the manufacturer’s claims hold up. First we take it to a local football field and see how fast it can clear 100 yards, then do some calculations to get an objective reading on speed in miles per hour. After that, we do a similar test to assess ascent and descent speeds, and all the while, we’re also taking notes on how responsive the controls are, how stable the craft is, how far it can go before it’s out of range, and what the overall piloting experience is like compared to other drones.
After we’ve taken the drone out to play for a while and jotted down a few notes about how long the battery lasts, we put it on the charger and grab a stopwatch to determine recharge time. Then we take it back out and do a hover test. By flying the drone in the least demanding conditions, we can get a sense of what the maximum flight time is. And finally, we take it out a few more good, hard flights to find out how long the battery lasts (on average) under normal conditions.
This category is better for those who need drones for commercial reasons, possibly for recording clips for an advertisement or a picture for their business’ profile, for example, or for residential fliers who want the best camera drone on the market. These camera drones for sale are professional in all aspects, with both the camera and the drone being high tech in accordance with the design.
Oh, and let’s not forget about the camera. In addition to a 12-megapixel camera that shoots video in 1080p at 30 frames per second, the Spark also sports a two-axis gimbal. This lets it mechanically stabilize the camera and cancel out any jarring, shaky movements — resulting in smoother, better-looking footage. This also gives it a leg up on the competition; most selfie drones only feature single-axis mechanical stabilization.
Most still cameras are 5 megapixels or higher. Therefore, do not be fooled by the claims of HD for a camera when the manufacturer is relying on the resolution for still photos. It is true what they are saying but not the complete story. Having HD resolution for still images does not explain the possibility of also having a lower quality for video-image capture.
For example, OPTI has a built-in Optiflow Sensor (a downward facing sensor), which functions by picking out the patterns on the ground to ensure that the drone maintains a straight position. ATTI, conversely, works a bit differently. With the ATTI, the drone employs other techniques apart from the external sensors to keep the drone in the right orientation and altitude. Thus, the drone can hover in place, or drift slightly around with the wind serving as a push. You will also find a GPS in some drones, and they help the drone to maintain coordinated and precise flights and landings.
Parrot’s new Mambo is different. Unlike most other mini drones, this one is actually designed specifically for kids. In addition to a boatload of motion sensors and advanced autopilot software that keeps the drone stable, Mambo also comes with a handful of attachments that make it more fun and engaging than a basic quadcopter. Inside the box you’ll find a cannon attachment, 50 foam cannon balls, and a grabber arm that can clamp and carry small objects.
I placed a request on Volunteermatch, where organizations connect with potential volunteers.

Similarly, having a few extra batteries won’t hurt, especially if you want to use the drone for extended periods of time at a go. Most drones over 50 have batteries that are available in six pack sets, with a charger also found within the set. These batteries can give you an average flight time of between 5 to 10 minutes before recharging, or replacing them if you don’t have a power source near you. Also note that battery time is usually affected by blade protectors, as well as when there’s a camera attached to the machine.
The drones we review are ready-to-fly models, so you can use them right out of the box. In most cases, you'll need to bring your own Android or iOS device to view the camera feed in real-time, but we've reviewed a few models that stream video directly to a remote control. We don't cover racing, industrial, or agricultural aircraft here—our focus is on aircraft intended for aerial imaging and videography.
Many manufacturers mount cameras inside the body of the drone. This is acceptable for casual photography, but if you want more professional results, consider adding an external camera mount, or gimbal. Gimbals allow you to place your video or still camera in front of the drone body, away from the vibrating motor and rotors. Gimbals can swivel and pivot, providing you with additional control over your imagery.
