in previous incarnations of flightsim I have noticed that the aircraft just don't want to spin.it is as if the aerodynamic model simply treats teh wing as one surface that stalls as a whole. For example, if you are in a steep turn and stll it, it just drops the nose as a whole and there is no tendancy to drop a wing, even if a goodly boot of rudder is applied. it would seem to me as though it just has a model that it applied to the whole wing as one surface and ignores yaw effect. its noticable that in amnouvers such as wingovers, the over banking tendancy that exists in the real world doesn't seem to apply - again as if it is simply calculating the lift of the wing as a whole.now, in 2004 i have founda couple of planes that want to spin - the corvair and super decathalon. I notice however, that other planes do not spin - even ones that I know do well in the real world.Anyone know the technical low down on this (eg. is it something that was introduced in fs2004, is there something about the aircraft model - such as modelling as two seperate wings)just to put in context - I'm not some jumped up spod who's read about aircraft spinning but doesn't know what its like int he real world. I'm a ppl holder with a couple of hundred hours, own shares in a couple of planes - including a de havilland chipmunk which is a true joy to aerobat and spin (yet the model I have for fs2004 does not). I also fly gliders - which they don't let you go solo until you have done a fair bit of spin training.

The without doubt best "spinning" models to date, are from RealAir Simulations. The designer/programmer spent well over a year with FS2002 models to perfect spins, recovery's, and all out rudder use, such as snap rolls & hammerheads. This was the goal & not a side effect; and the spin flight dynamics as well as side slips beat anything, in any desktop simulation that I know of. With the release of FS2004, Microsoft made some programming changes, which also required RealAir to do some re-programming.As to myself, I've spun & recovered many times in a Pitt's S2B. It was one of those things we just liked doing after a few hours of aerobatic training.http://www.realairsimulations.com/L.Adamson

cool... always fancied a go in a pitts.the chipmunk it a joy to fly, but its more the gentle/gracefull aerobatics. I'l have a look at this site.thanksandy
