Flying a drone manually is fun, but there are some manoeuvres that are virtually impossible to fly smoothly. Circling an object or person, for example. You’d need to constantly change the balance of forward/backward and left/right inputs to fly the circle in the first place, then simultaneously keep rotating the camera by just the right amount to keep it pointed at the centre of the circle. Anyone who can do that perfectly is either a drone genius or has way more than the usual number of hands.
The DJI Go app offers a range of intelligent flight modes – aka autonomous flying. But a third-party app, Litchi, goes even further: it allows you to program your flight path in Google Earth before you even leave home. As soon as you arrive on site, just load the pre-programmed flight and hit Start.
