Looks like he got his q's answered, but in case he comes back...this may help: I was told the other day the default mapped button for firing all the guns on bomber + your drones, that have proper angle on an nme is the letter "n"
One thing I was also told, was that you can jump from drone to drone instead of staying in the middle one and having a bandit remove them from the 4 & 7 o'clock positions. I don't remember what they said the command was though.
