Already got the dragon working. All I had to do was add the flags "player_allowed" and "default_player_ship". Aside from that, and modifying the weapon banks to allow for Shivan primaries with player controled ships (no weapon diffrences, just enables player use), it's the same dragon the computer uses. It moves the same, speed is the same, and weapons are the same.
And there is no way I'd allow an advanced starfighter, like the dragon, to reach a top speed of 95mps (with burn, bleh).
Oh, beware though, by default, shivan primaries are weak, which I guess means that you have lots of allies

But not too many.
[EDIT] Unless I can figure out how to remove weapon banks, the Seriphem and Nephilim will likely not be use, due to the weapon's in the HUD not showing anymore then 2 primaries and 3 missile banks. May not be a big deal, as they'd have only bombs, but you can't see, nor switch them. [/EDIT]
