I'm a bit concerned about the physics model of flightgear. Are there certain physical limitations built into the sim, that makes paraglider physics impossible to model? I'm thinking particularly about the pendulum effect. Of course, everything is possible when you have access to the source

[Flightgear-devel] Paraglider model

2004-02-27 Thread Gunnstein Lye
Hi all, (I'm new to this list, my apologies if this is the wrong forum for my questions.) I am a paraglider pilot who have been toying with the idea of modelling a paraglider in a flight simulator. I made a model in X-Plane first, but had to give up because X-Plane was too limited to be able
