This add-on contains five hot air balloon vessels based on the Vessel Builder configuration files for Orbiter 2016. Maybe it will work with some later Orbiter versions too.

The add-on author: misha.physics
The Vessel Builder author: fred18

INSTALLATION:
1) Download and unpack the Vessel Builder add-on (only if you do not have it yet):
https://www.orbiter-forum.com/threads/vesselbuilder-for-orbiter.36956/
2) Unpack this add-on.

There is a scenario with all hot air balloons located in the "Hot Air Balloons" directory.

CONTROLS:
Use the following default commands on numpad:
"0", "." for hover engine, "1", "3", "2", "8", "4", "6" for ROT RCS mode, "1", "3", "6", "9" for LIN RCS mode.

Use "F8" key to switch between the 3D cockpit and standard 2D cockpit.

Textures are used only for a basket, so you can change colors of balloons by editing the corresponding MSH files.

Use the Scenario Editor to create a new vessel. There are five hot air balloons in /VesselBuilder1/HotAirBalloons directory:

1) BlueYellowRed
2) Classic
3) Germany
4) Green
5) Ukraine

www.orbiter-forum.com

You can leave your comments/ask questions on the forum.

Thanks everyone for your help!

(These hot air balloons were released on the Vessel Builder configuration files at the request. Later, I am going to release these hot air balloons based on Lua as part of a larger add-on.)
