 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.
