Wow, Condor looks good since the last time i saw it, is it a bit realistic? Maybe Rotty knows?
For soaring condor (and silent wings) are much more realistic than MS FS. The flight dynamics are very good (planes do not only spin or show wing flutter at high speed, but the spinning/flutter behavious is depending on weight, ballance, altitude and how long you stay in the situation. Sometimes with a fully loaded glider you will not be able to exit a spin or the spin stabilizes if you stay in it longer and it becomes more difficult to recover). The lift model is very good and features thermals, ridge lift, adiabatic lift (depending on how high the sun i standing) waves etc. Thermal strength is also depending on the surface (fields, grassland, forrest).
If you are into soaring, I can recommend this sim.
