They are so popular that we have seen one at some point. They can be fixed wing or rotarywing, and are classified according to the number of engines, the most common being the 4 engine or rotary wing quadcopters, although there are also 6 and 8 engine or hexacopters and octacopters, respectively

Their use should not be underestimated, it involves risks for operators or pilots and the environment where they are used, for this reason it has been improved and continues to review the regulations related to the responsibility of owners, pilots, organisations that use them, associations or organisations linked to aeronautical safety.
Among the most frequent uses are:
(a) Transmission and/or recording of images, for advertising purposes, panoramic views of sporting or cultural events, traffic control, exploration and evaluation of areas of difficult access, surveillance and security functions, rescue and;
(b) Data capture for precision agriculture and process control, among others. More recently, it has also emerged as an option for parcel and package delivery.
Drones have proven to be very useful and continue to evolve, so it may be attractive for you to venture into this area. If this is your case, remember that formal training as a drone pilot is essential.
The proper and responsible use of technology makes all the difference.
See you soon dear ProjectHope friends!
