Depending on how much your miniatures weigh, these Topgun Dogfight Flight Stands should work:

As you can see, they permit virtually any attitude of climbing, diving, and banking flight to be represented, including even inverted maneuvers. They have five antenna sections, and extend from 7" – 22" in height.
I've used them with the diecast metal, Titanium spacefighters, for Star Wars and Battlestar Galactica battles, so they should work for your minis.
Magnets are used for attaching the minis to the tips of the stand's antenna, which also have magnets.
I sell them in matched polarity sets to make gaming easier.
They're also great, as you can see, for aerial wargaming with miniatures in 1/72, 1/100, 1/144, 1/200, 1/300, and yes, even in 1/600th scales.
