It's released under the same, MIT license as the original mod.

Summary

Tired of walking or waiting for trains? This quality mod adds a helicopter to the game.
Comes with custom animations and sounds, a machine gun, a rocket launcher, helipads and a remote control.
The energy consumption is very high, high-energy fuel is recommended.

Adds a new research that you have to unlock before you can build it.
Ideal for getting from A to B quickly, exploring the map, building islands and nuking biters from the sky.

API

Other mod authors can register their own helicopter through an API so they behave the same! README
