Corvus Blackstar support

As per picture really. Anyone back up their Corvus with other flyers or is it just not worth it?

Not really played yet as need to learn rules and finish off army. I have a Corvus to paint and just wondered whether investing in a couple of flyers / speeders to support haha.

Is it just a case of fly in, drop off squad, try get a shot off, blow up? Or do you get some hit and run chances?
