While each mode is unique and important to understand, most of them still provide the basic function of flight-stabilization and assistance tool. For instance, OPTI typically features an Optiflow sensor within the drone, which is a downward facing sensor capable of identifying patterns on the ground and helping the machine to maintain a straight position.
It is important to understand the warning about wind because wind is the most likely cause of serious problems with these drones. The drones in this category do not fly well in the wind because their motors are not strong enough. It is easy to lose them in the wind, so do yourself a favor and do not attempt to fly them, especially up high, if there is even the slightest wind outside. It would be better to fly them indoors if it is a windy day.
While the Mavic 2 Zoom will still set you back £1,099, that is £250 less than its brother, which makes choosing between the two a tricky choice. While it lacks the one-inch sensor, 10-bit HDR video and adjustable aperture of the Pro, its image quality is still excellent and more than good enough for epic YouTube videos. That spare change could also be put towards a spare battery or a ‘Fly More’ bundle. Whichever way you go, the closely related Mavic 2 Pro and Mavic 2 Zoom are the best all-round drones you can buy right now.
Go for a model which has easy-to-find spare parts even from your local store. It’s highly recommended that you should have at least an extra pair of propellers, apart from the ones already on your drone, including the appropriate tools needed to replace them when they accidentally break down. Furthermore, there should be sufficient protectors available for your quadcopter, so as to prevent damage both to the device and injury to people or property damage in case of any clumsy flights or landings.
Yuneec also has a model with a Micro Four Thirds camera. Its Tornado H920 is a huge drone with six rotors and room to hold three batteries, giving it an unheard of 42-minute flight capability. Its CGO4 camera is essentially a custom version of the Panasonic GH4, a favorite of many a terrestrial videographer. It doesn't record uncompressed video like the Inspire 2, but it's less expensive.
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.
