I did pretty well with two Hessian standards mounted on top and bottom, then two pulses on the wings, and two BR's on the cheeks. It was rather gnarly and powerful. The two cannons were for taking apart NPC's while the heavier guns took out players. All in all, it worked. The Heimdall is stupidly agile, so you can joust bombers and even VHF's.
"THE HULL HAS BEEN BREACHED AND THESCIENCEIS LEAKING OUT!"
The loadout that Akura mentioned is good, however....
With 2 Pulses and rest Cerbs you will be able to kill any gb, or any trader, but you wont be able to do much damage to small craft. Sure you could kill an occasional noob bomber or jousting fighter, but not more than that.
With all primaries, you will still be able to take on gb's and traders and you will also be able to do more damage to small craft. Its just that taking on gb's would take a bit longer then taking them on with Cerbs.
I don't shoot backwards with it, because it has few guns and I suck at it anyways:D
So I use 3 pulsed and 3 razors. Even if the powerplant is kinda meh, it worked...I killed both other heimdalls with setups like cerbs or prims, and hydras, so...
Oh yeh, also rheinland gunboats...you can simply fly circles around them:lol::lol:
