The toy version of the FANG is a armed gyrocopter, which looks a little to fragile to really do anything useful.
I found a couple of helicopters from Matchbox that I am going to use as FANGs. To me they look a little less gimmicky and less likely of being shot down with a slingshot. I still need to add a couple of rockets or pods to the weapon mounts. They will be used for terrain or placed on magnetized flight stands to buzz around the board.
I also picked up a bunch of Airfix 1/76 Landrover trucks. That I painted up as transport trucks to get the troopers around and a ambulance that was converted to a communication van.
