I have ALL of the major sims and FS One is definitely NOT a "great one", both in terms of graphics nor in sim realism.

It sounds like you didn't really get too far into Realflight.

I had high hopes for FSOne, given that they touted fluid dynamics modeling (Ala X-Plane ). In actual practice however the models did not respond nor behave like their real life counterparts.

Of all the planes FSONE models the Alpha 40 ALMOST gets there, but in the end still falls short of real life behaviour even with a lot of adjustment of the plane.


I ( still own ) a good number of the planes in FS One ( hence my purchase ) but discovered that the physics just didn't cut it, forgetting about the abysmal graphics... though it had a wonderful initial user interface for the novice.



Of the big sims, Aerofly 5.5 and Realflight 5.5 best imitate the behaviour of real life planes with a bit of tweaking on both.

The latter does the best job, but the upgrade from Aerofly Deluxe to Aerofly 5.5 gave the sim physics approaching that of RF5.5. They are starting to "feel" quite similiar.

RF5.5 models and permits tweaking of minutae that impact the physics of the planes and helis that unfortunately AF5.5 still does not, but the latter is coming along nicely ( and it does very well on non-high end machines due to the more efficent OpenGL implementation versus DX ).


The user created planes in RF5.5 in many cases are far more accurate than the same planes in FSOne... which is why I've seeen magazine articles explaining and teaching 3D techniques with user created RF5.5 I've worked on.

Aerofly 5.5 still doesn't have airfoil stalls quite right and an improvement in that will IMHO make a big difference... ( if we could only get a better and more diverse physics editor in it too and add a bit more second order modeling...).

BTW: for some reason one thing RF5.5 does a poor job with is co-axial heli modeling, but that's a minor point.
