drones

I'm looking for advice on adding drones to my T3D game. I already have the AFX kit.
The drone needs to act like like a turret gun in that it has a gun and needs to shoot at hostile enemies that come within range. The drone normally hovers in base guarding it.
the drone can be called by a player on a map who is looking to capture a remote point. When called the drone will fly from base to a set location(capture point) where it needs to stay for about a minute while the capture occurs. During this time it can be shot down by enemies which would halt the capture.
So drones need to fly, shoot enemies, and be shot at.
it also needs to broadcast a power feed either positive or negative so that if i'm a friendly near it I get a positive power feed, negative power feed if I'm a enemy.
Additionally drones can be called to any part of the map to provide power and firepower. The player, in this case a client controlled tank, call them by toggling a keyboard command.
There will be multiple drones per team, around 6-10.
I'm not sure where to start on this. Should I be combining AIPlayer with FlyingVehicle, any out of box solutions for this, modify the sci-fi drone in AFX, etc....
I can try coding this from scratch but as I usually do, looking to reuse work to save time and effort.
Hope that helps explain what I'm looking for.
Suggestions appreciated, thanks!
