Why my Physics Thrusters aren't working?

Hello !

I’m new with Unreal Engine, but I’m following this tutorial about creating a space flight simulation (Create a Space Flight Physics Simulator in Unreal Engine 4 - YouTube).

In order to achieve that, I worked with physic thrusters, to move my pawn. So I placed them as it is explained in the tutorial (see attached photo : how I placed them and how I configured them). And I configured everything right (I think) in order to make them work : the thrusters are parented with my static mesh, whitch is on moveable, I have simulated physics on my mesh.

I’ve created a Blueprint which is activating my thusters when I press certain keys.

But the fact is that nothing is working : the ship is not moving at all, even if I check “Auto activating” for the thursters.

The configuration I made.

Am I missing something ? I don’t understand why this isn’t working ?

Could someone help me please ?

Thanks !

Changed the thust strength, it works now ^^ sorry !
