Realistic methods of propulsion without friction involved

I'm working on a hovercraft type vehicle which hovers off the ground and thus has no friction. My question is, what method of propulsion should I use to ensure that this acts "real"?

Because I have no friction, my method of propulsion also has other problems. For example, right now, my hovercraft can take an 85 degree angle no problem and fly off the top of a ramp extremely fast; this isn't realistic. How could I fix it?

Thanks, Chad

Hi Chad, have you tried experimenting with dynamically adjusting the drag of your object?

You haven't given enough information. Start by showing how you accomplish your frictionless hovering.

@Zylar I get the inverse of the distance of my hovercraft from the ground and AddForce that amount to a rigidbody gameobject connected to my hovercraft by a fixed joint.

@Dendro No, I haven't, thanks for the tip.
