<h2>Hi Steemians!</h2>
Since 2 years I am developing aircrafts for an open source flight simulator: 
<a href="www.flightgear.org">www.flightgear.org</a> Flightgear is free and runs on windows, linux and mac.

Iljushin 76 MD some vehicles, hot air ballons and a roziere ballon.

Searching a flight simulator for free and realistic in flight-dynamics I found this one and after a while I started to improve some things, ending up as developer with my own hangar.

<h3>How to make an aircraft in a short overview</h3>
- Get the model from any free model page or taking an existing one from the 650 (!) in flightgear.
- 3D modeling with blender, programming in nasal and xml
- Researching everything about the aircraft on the net, saving pictures, manuals etc.
- Moving the main surfaces (rudder, aileron, elevator, gears, flaps, slats, spoiler)
- Making a lot of test flights and step by step improving the FDM (flight dymanics of model)

- Getting more things animated: up to 180 instruments in the cockpit, switches, lamps, doors
- Making it popular by anouncing it to the newsletter and in our world wide comunication tool Mumble, also getting tests done by other players.
- Trying to fix each problem as soon as possible, so that the fun can start.
- Making more animations like paratroopers, fuel trucks, payload loading and unloading
- Asking others to make liveries and updating every step on git.

As it is open source we get nothing from it, just better aircrafts and a lot of fun by making flights together,
