How to assemble a quadcopter capable of flying up to 50 km?

Question

Do it yourself

There is an idea (and financial opportunity) to create a flying device that, according to GPS data, can transport (by air) up to 5 kg of weight. The total distance that needs to be "covered" is 700 km, you can make 15 copters with a range of 50 km, or one "aircraft" that will fly this distance without refueling or recharging.
I am ready to consider investment options, purchase of prototypes, testing and other things.
I will be glad to receive feedback [email protected]

Answer 1

drone to help you!

permission to fly will be difficult, if not impossible, to obtain.

Answer 2

such a long-range will be the size of a car. like in the movie avatar)
the plane is more energy efficient.
and problems with the law are very likely, tk. such a device is essentially like a cruise missile comes out. with corresponding options for bad use.

Answer 3

No copter can fly far, because it’s not easy for us to fly between cities on airplanes, and not on helicopters.

Answer 4

Answer 5

In my opinion, it is unrealistic to construct such a thing with a quadric , because it is controlled by GPS. But you can think about this issue, since it is a very interesting topic. I think that even if this is possible, the device will not be so compact. It will be interesting to try ...

Answer 6

In my opinion, this is only possible with a nuclear power plant. Accordingly, its minimum possible dimensions, taking into account the power per unit mass, will dictate the minimum size of the device.
PS Maybe then a tiltrotor, and not just an n-copter?
