Moving distances for Wave serpents help required?

[Cheds234]

I have just started up my eldar army again after a long period of sitting on the shelf collecting dust, and! now have the new copy of the rule book. Having read though and now played a couple of games i have been told that the fastest my wave serpent or a fast skimmer can move is 24 even if it has the star engines is this true??

I was also told that other rules for the eldar tanks and bikes and walkers arent worth taking either?

Am i just being advised incorrectly or are these horrible truths?

It's a fast skimmer as I recall, so you can move 24" flat-out. Note that you can also move 6" as if you aren't even moving, and 12" and still fire one weapon+def.
