  Make sure that you Motion Analysis option is selected. Simulate the "Real World" as much as you can. Apply the gravity in one direction only(usually down). Apply a motor on a part that you want to move(Rotary, Linear or Path), apply Material, Friction and Contacts to the parts and apply Force in the desired directions.

  I hope this helps.

     ill jus check out all that you've mentioned . I've used Motion Analysis oly . I've added gravity in the downward direction alone . I applied the motor in the middle ring and added a rotation about its axis . I've applied material . I haven't friction or contacts or force ! Are these the reasons for the error ? ill jus try it out :)

  I have created a realistic motion study and animation video of this model. Please check it out to see if the results is what you were expecting. I believe it is fairly accurate.

     Hey martin . i jus checked out the animation n saw tht its jus what i expected . But i think you have reached that by capturing frames . But what i wanted was for a motion study to mimic what will actually happen to the gimbal due to the force of gravity ! i want the same thing that you brought up with your animation to happen in motions study ! thanx for tryin :)

     Hi Amos,
     In this new SW model I used the motion analysis function for animating. Normal gravity applies to this model and the motor is turned on for about a second, after that the rotation speed degrades normally over time due to mechanical friction. Air friction is the only missing element in this model. Maybe there is a way to mimic air friction but I'm not certain. Not sure if this what your looking for but best of luck to you.
