Hi Alex,

if you only apply the torque force once to your object, it is like a single impulse and you might not get the result you need.
This is not an answer to your question but you need to apply the force over time (several frames).

If you and a few friends try to push a car until it runs, you need to apply your forces more than just a second to make the care move...

It is the same with GameStudio Physics.

Say you apply a force of 500 to an object with a mass of 10.
If you have a very high frame rate, the force is applied for just one frame and has less effect to your object as it would have if you had a low frame rate.

Your solution has to take this into account.

My solution was to lower the force and to apply it for several frames.
Dougs hint helped me in that case.
