How to make a quadcopter, hexacopter fly?

Question

Do it yourself

I decided to collect this miracle with a friend.
Before implementation, there are 2 unresolved issues, maybe you know where to find a solution?
1 . What is the best control system to choose?
1.1 It is possible via wi-fi, in such cases it will be possible to control it within a radius of up to 2 km.
1.2 Radio control, there is about 10 km.
2.3 Satellite (well, this is a perversion of course)
2.4 Through the Internet
2 . What software is needed to make it fly?
Or go freelancing, then who to look for?
Of course, a hexocopter is better, but a quadrocopter is simpler.
Thanks

Answer 1

There is no answer here, I went further.
Well, thanks for the company!

Answer 2

if you ask such questions, you do not have your "2 unresolved issues", but nothing at all. Zero without a stick.
Hurry to the specialized forums! Frame, motors, controllers, power supply, device firmware, control equipment, telemetry, fpv ..
And this is just the tip of the iceberg!
you can add to dimonchik2013 's answer , for example, multocopter ru or rc-design ru

Go to the store, buy and fly ;-)
Radio-controlled models (there are also a lot of links to articles here on Habrahabr).
