Rigidbody mass not affecting inertia

Hi, I’m working on a 3D game with a hovercraft.

They work as a rigidbody using apply_central_force to move. The hovercraft’s mass is 450 kg, yet when a 0.1 kg rigidbody is dropped the hovercraft will rebound ridiculously far as if hit by a freight train!

I would expect the hovercraft to barely register such a collision due to having a comparatively much higher mass. I also have the issue of not being able to push light objects either despite the mass and speed difference indicating it should be otherwise.

Is there something about the physics system that could be causing this unintended ignoring of mass?
