In easyfly lots of things can be modified (see also topics about changing bitmaps). http://www.ipacs.de/ubb/biggrin.gif
For each airplane exists a parameter file in the directory \easyfly\aircraft, e.g. cap232.dns.

Modifying parameters like ca and cw (aerodynamic values) causes a different behaviour of the plane. Let's make an example:

The Discus glider rather seems to fly like a 2 meters slope racer than a 4 meters thermal soarer.
Modify these lines in discus.dns:
Fuselage.Ca = 1.706980; --> 17.06980
Fuselage.Ca0 = 2.380000; --> 23.80000
Fuselage.Ca1 = 0.595000; --> 5.95000
The flight feeling will be distinctly different.

One more example is to slow down the speed of the Cap by increasing the cw of the fuselage:
Fuselage.Cw0 = 0.2000; --> 1.0000
Fuselage.Cw1 = 0.2000; --> 1.0000
Fuselage.Cw2 = 0.2000; --> 1.0000

Ok, these were first tests and will probably not give an excellent result. The values and all the parameters are not yet examined in detail, but it is clear now that the user can modify the flight model. Perhaps there are some more people interested in trial and error. http://www.ipacs.de/ubb/smile.gif

Of course, you also have a safety copy of your files. Do not blame me for any crash of your aircraft! http://www.ipacs.de/ubb/wink.gif
