Drones are used for a variety of applications such as search and rescue, inspections, security, surveillance, scientific research, aerial photography and video, surveying, cargo delivery, and the like. Further, drones can be used for personal transportation, i.e., manned drones. Mostly drones will be autonomous and battery-driven because battery technology, which is becoming cost competitive and improving rapidly, enabling batteries to store more energy while decreasing in size and weight of the drones. In addition, some drones comprise mainly a single unit with a pilot or a passenger inside the drone. This type of drones could be adequate for limited flying time using heavy batteries and inefficient propellers and rotors. Each drone type may not be compatible with others from different manufacturers. A prior art, US 2016/0167775 Al of Joniot Jaques, discloses a drone comprising: two contra-rotating annular propellers defining a plane therebetween which is referred to as an equatorial plane and is assumed to be horizontal, means for driving the propellers, a load arranged below the equatorial plane, and means for moving the load relative to the equatorial plane, an enclosure referred to as an upper enclosure filled with a gas or a gaseous mixture having a density of less than 1 and arranged essentially above the equatorial plane, and an enclosure referred to as a lower enclosure filled with a gas or

, DK 180724 B1 a gaseous mixture having a density of less than 1 and arranged essentially below the equatorial plane, the load being placed inside the lower enclosure. However, above- mentioned prior art fails to teach or disclose, a drone comprising: one or more ballasts are slidably positioned underneath the seat/seats, stretcher, cargo hold, wherein the ballasts are configured to slide on one or more lower curve ring rails by an additional electrical motor for attaining the center of gravity into the allowable range, thereby forcing the rotors, gearbox, electrical motors, basket, and the circular shell structure in a sideways angle to strafe left and right, wherein the ballasts comprise a cargo for people, wherein the additional electrical motor is connected to the lower curve ring rail via a gear.

In the light of above-mentioned problems, there is a need to provide a drone for a pilot or a passenger and allows to execute an optimal flight path using a control system or flight controllers. There is also a need to provide a drone having simple design, flying stability and capable to fly long hours using batteries and also allows for flexibility, convenience, and is standardized so that the drone may be widely utilized while decreasing in size and weight.
