Did you know you can also use your sparrow as portable explosive C4? I've actually used this before to kill the starting mobs at the Sepkis boss arena. Edit: Pulling down on the joystick while in the air on your sparrow increases hang time. Another edit: seems a lot of people do not know that the new Tumbler sparrow actually has tricks other than flips. Use the d pad in mid-flight, and you will see :)
