(adsbygoogle = window.adsbygoogle || []).push({}); So I recently unlocked the UCAV, oh boy.
This one of the hardest things in the game to be useful and do something with.

UCAV is pretty good it a flying bomb.
Same controls as the SUAV so inverted controls, but with a deadly pay load.
You need to hit people head on in order to kill them until you unlock the air burst mode that said if you exit it acts like the air burst.
My biggest tip is to exit near a target and let it explode.
Won't instant kill anything but does disable most things.

Next up the range it pretty decent at about 400m.
Fires straight up into the air before going in a straight line.

Another bit of advice is to aim it in the direction you wish to land over turning it.

Attack jets
I found jets pretty easy once you get used to the camera my best tip is not to boost at all. I did change the controls so that fire is L2 or L1.
