The game uses the "PHYSICS" behavior
Here is where i got started learning about how to implement it.
https://www.scirra.com/tutorials/64/phy ... the-basics
In my game the ship has the physics behavior, when you press a key, it applies a force in a direction to make it fly, or turn .
If you go to your file menu in Construct 2 and click "NEW", you can choose a whole series of example programs starting with "Physics Basics" and others that explain forces, impulse, joints etc.
These all helped me to get going with physics.
I look forward to seeing something like your cool 3d robot flying around
