   How to control fall rate in Bullet API
  I am not sure how to control the fall rate of an object in bullet when its a dynamic object. Would I use calculateLocalInertia()? I tried various values, e.g. (0,1000,0)  and (0,-1000,0)  no luck.Thanks!   
  Nevermind I see you can set the gravity in the setGravity() of btDiscreteDynamicsWorld.BTW how can you delete a post?
