What the title says.

I want to make a flying vehicle. I made the physics, they envelop the vehicle well and everything's fine. Except for the fact that such vehicle doesn't move at all.
The vehicle type is "alien fighter", as the banshee, and it has properly set animations, speed and acceleration settings. The problem lies within the physics tag, since it works with the physics of the banshee. But I don't know why, with my physics, it doesn't move at all. Is there any comprehensive tutorial about physics? How do they work, how you troubleshoot problems and so on? The only one I've seen was pretty much straight forward with little to no useful informations, and it didn't event cover flying vehicles.

Found this.

This tutorial doesn't say anything at all about physics. The creator used a physics tag he already had.

Oh man, I know the answer for this but my crappy English won't let me express it :/
I'll post some pics later

Please yes. I can't stand my sabre grounded like that. I got other physics tag to work mainly because of luck, but never understood the mechanism behind.

Edit: flying vehicles, in order to fly, MUST have exactly two powered mass points. Any other number cause the vehicle not to fly at all; it's interesting to note that there is no need for these powered mass points to be actually referenced by any mass point: it's just enough for them to be there.

The problem, now, is that the saber flies, but it trembles. Like, it shakes when turning.
