Control The Speed & Strength Of Dynamics

Hi All,

I am applying dynamics to a complex mesh (helicopter). It has lots of parts. I want all the pieces to fly aprt. I have set the radius, mass and center for all the pieces. They do fly apart, but in a non-realistic way. I also have setup some parts with a collision sensor, controller and actuator to influence the rotation.

I am wondering, is there a way to control the overall speed and strength of a dynamic simulation?:spin:
