Wheel Constraint Setup on Plane causing it to fall through map?

Hello, all!

I am having an issue where my plane deletes itself once it hits the map. I’m assuming it’s being flung. This is an example of what’s happening (Gyazo GIF):


This is how I have it rigged.

If I disable the springs, the plane doesn’t fall. Below is how they are setup

I figured out if I set the Damping to 50, the plane doesn’t fall through the map, but it doesn’t sit well with the wheel arms. When I increase it to 100, it falls through the map.

My Wheels are CanCollide true, but my Physical Wheels (cylinder that covers the wheel) is set to false.
