Hmmm, I guess by definition of the lift crystals, they cannot do that, and from the sounds of it, neither can the trim crystals.

Why wouldn't they? Not being argumentative here; I genuinely don't see why they wouldn't work in all three dimensions.

Because to turn a ship left/right you need to give the crystals the ability to move sideways (not just up-down). And if that's the case, then this means you can actually use the crystals themselves to move the ship forward.

Think of them as the attitude thrusters on a space vessel: they can move the ship, but they tend to provide a few orders of magnitude less thrust than the actual propulsion system. They're the reason I admit I'm making assumptions about the attitude crystals: any airborne vessel needs to have a way to change its attitude in three dimensions and not just move.

The difference, I think, is that the trim and Lift crystals are not actual thrusters, they are anti-gravity pumps. They can tilt a vessel by applying less lift to a port-side trim crystal than the starbard-side, but the forces are always acting only in the vertical plane in direct opposition of natural gravity, and so they cant actually apply force in a horozontal direction. I think the horozontal rotation (ie "Yaw", for those that dont want to look it up like I had to :p) comes from teh interplay of the "Control planes" (wings) and the asymetric pulling from the various Etheric Webs.
