Since our last talking, i have tried to rebuild from 'souvenirs'
the FDM YaSim model which was for me a _big problem_ the result with the
CVS release is good. Better than before with an older fgfs release (9.4 ??)
So now, in addition to the usual retractable gears,
with _gear_ which define several contact points, i get a good position of
the aircraft (mains gear-up).
Thanks and Sorry for my _certitude_; i was not up to date.
