--
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.

Default Controls

Shift+E and Shift+Q - Start and Land.
Up and Down Arrows - Increase and Decrease flight height.
Shift+L - Floodlight (at night).

If you have the remote control in your armor grid:
Shift+G - Open the remote control panel (there is also a small button in the top left corner).
Shift+F - Send the nearest helicopter to you.

Known issues

• Landed collider and smoke may be slightly out of place.
• You may get stuck when exiting the helicopter before it is fully landed. Simply enter and exit the vehicle again to get freed.
• Helipads aren't surface-aware... Keep that in mind when playing mod such as space exploration
• Underlying shadow is different in landing automatically vs manually
