What steps will reproduce the problem? 1.1.take any YASIm helicopter and put it on the ground with engine stopped\r\n2.1.just look- depending on the fdm config you see it imemediately, or after some time. But you will see it.\r\n\r\n1.2. Start the engines\r\n2.2. just look What is the expected output? What do you see instead? I expect, that the helicopter will rest on the ground without moving. Instead it moves more or less to he right or left. Depending on the settings faster or slower. \r\nWhen Engines are started, the heli will begin to turn- in reality even then it keeps without moving. What version of the product are you using? On what operating system? win32, GIT August 2010. It has been reported for every system and for a long time now (>4 years) Please provide any additional information below. The strength of the movement seems to depend on:\r\n- distribution of the ballast: Bo105 is a good example for keeping the movement small.\r\n-Approach speed: the lower the better. But: it will sink into ground quite fast after adding some weight.\r\n-Friction-factor: setting high even increases the movements.\r\n-compression and spring: the higher, the better. But unrealistic for a metal skid....\r\n\r\nThere was once a try to solve this, but never heard again from it....\n\n_Original issue: http://code.google.com/p/flightgear-bugs/issues/detail?id=155_"}}
