Units flying height

I don't know what happened to my topic..
So, the question was: when a flying unit with Movement Heignt = 0 comes over a ramp (such as Ramp Naga Small), its flying height increases a lot and not even triggers can reset it to 0.

Is there anyway to prevent it, without changing the movement type?
Thanks in advance,

Fly height is the unit's height above the terrain. When the unit goes over a ramp, the terrain height increases. Let's say a unit has a fly height of 50 and is on ground that is 0 units high. The unit then goes over a ramp which is 25 units high. The unit will now be 75 units high. You're thinking of the unit's height above the ground, not the unit's fly height. If you want to lower a unit below the terrain height, you can always give it a negative fly height.

There's something called a flyover height in the object editor. Set that to zero and I think your problem is solved.

hum... I didn't explain my problem very well but Relyte's suggestion solved it ^^
I menat that when the unit got over the ramp, its flying height increased only over the ramp, and in a huge scale, so it didn't touch the ground (it was flyer just to remove collision with ground units).

But that's because the Fly-over Height of the Ramp Naga, that was 200

Thanks both!
