One of the most important things to do before you fly your drone out is to understand the basic laws in your country. You can’t fly, near airports and military bases, so check before you head out.
You cannot fly one within 150 metres of a congested area. Similarly, you cannot fly one within 50 metres of an individual. Also, if you are doing any flying for commercial reasons, you’ll need a licence.
You can’t fly a drone in the rain , and you must not fly through clouds. Sunshine and rain are easy to spot, but wind speed is harder. Drones vary a lot, but typically if wind is below 28mph (45km/h) then most drones will fly.
How long you can keep a drone aloft is limited, due to the limits of battery technology. At present, you can expect to get around of 20 minutes’ lying time per charge. Professionals keep it to around ten and carry many spare batteries that they swap in for the rest of the shoot. The best at present are Lithium Polymer (LiPo).
