Note: FlightGear is highly configurable through editable XML files. You are free, and encouraged to, make changes to aircraft flight models and any other feature you wish to change for your personal satisfaction or to share with other FlightGear users. The flight model is not defined in a binary file. It is easy to modify (given enough knowledge). Although the install is binary, most of FlightGear's system is open to configuration through XML files and NASAL scripting.
