LOL @ the RCXD kills. They are annoying, but not much different than the Predator on MW2 other than being easier to get (3K vs 5K). The team I play with prefers the Spyplane, as it definitely returns more team kills than one RCXD car.

My normal combo (I mostly play Hardcore TD)
AK47u sub-machine gun, iron sights, suppressor
Strela launcher (usually ditch this one ASAP for weapons laying on the ground)
Ghost Pro
Slight of Hand Pro
Marathon Pro
frag, nova, claymore
Spyplane, Care Pkg, Chopper
