My Orca is currently parked at the Shipyard since I don't have the credits for a Re-Buy.. so won't fly it again until I have... I'm down to flitting about in a grubby Cobra again!..
Build wise, mine is your standard Trade in Style Orca, A-Grade on Thrusters, FSD, Distributor and Power Plant.. 5A shields, 144 cargo, discovery scanner and a small vehicle bay just because landings should be done in style too!.. (Now I need a red carpet addon to the vehicle bay and some shiny hubcaps for the buggy!)
I have a Size 3 beam laser on gimball, and two turreted size 2 pulses for self defence. One A-grade shield booster, 1 PD turret and two chaff launchers to frustrate those clipper pirates that one cannot just boost away from.
As for Ramming and the FAS, I met one of those on my Grand Tour of the Rares Producers... a CMDR in a FAS, (or possibly Dumpship, but I think it was a FAS after all, I found is CMDR page online and it said FAS), anyhow, he was blockading Xihe when I came there to get those rare robots. He went bumper car at me in the landing bay and told me to leave Xihe. Can't have such behaviour here, thought I and went outside to recharge my shields, then I came back. He came flying at me at speed, and we made a well-nigh head on high speed Ram-on-Ram outside the station.
It did neither of our ships much good, both lost shields and took serious hull damage.
Unfortunately he won the shooting match that ensued, after all, I did not have armour since I wanted max jump range, he probably had armour... so one re-buy later I can't afford risking the Orca again.. so therefore re-enter my trusty old Cobra.
