Cargo multicopter

[cargorotors]

Hello friends!

My idea is cargo copter. I want develop model, that can move 15 kg to 3 km. distance.

I want to ask you to suggest me something according to my questions:
1. What motor better to use? How to choose?
2. What frames are the best? How to choose?
3. What flight controller better to use?
4. How to calculate flying time and choose battery?

And etc.

Can you advise me somebody, who can help me to develop this model?

Thanks!
