Unfortunately, you cannot drive a scarab in any of the halos. You rarely even see them in halo reach.
yes.
Yes, you do.
You cant
NO, you need a flash drive for everything.
OK first that first answer was someone who NEVER! played HALO (WHICH IS AWSOME BY THE WAY!!!) you can't drive one in halo without modding. BUT maybe in Halo Reach you can >: )
Falcon, Banshee, Longsword, Pelican, and phantom
you need an xbox hard drive
unfourtuneatly you cannot drive a scarab but i know there is a glich when you are speeding with a mongoose with a friend on your back with a rocket lancher you then shoot the ground after coming up a hill towards the scarb and with some luck and a couple of tries your on then kill every one on it until it is just you leftand your friend now if you both go to the same place on the scarb ie the side it starts to turn in that direction have fun i think there is a video on you tube just type in how to drive a scarab(dont go for hacks)
You can install Halo Reach to your hard drive like any other Xbox 360 game, however the game must be in the disk drive in order to play the game.(but if you have to put the disk its a waste of time to installing it)
Nothing

Yes you can drive/fly the falcon on halo reach , there a 2 types : one with a turret on the front and 2 machine guns for passengers , then the other one has no turret - just machine guns for your friends to fire.
