I explore in an A rated Orca, with engineered FSD I get 42.5 ly or nearly 45 when low on fuel. She flies beautifully, and with a grade 1 power plant mod she skims nicely. The flight model is beautiful and the bridge is elegant and easy on the eye, much better than flying a ship from a cage hanging of the front of it. Got loads of internals too.
Orca's cockpit view is mediocre for comprehensive exploration though, since there's no view down and not much view to the right. You're supposed to be looking at what's OUTSIDE the bridge, not INSIDE of it.
Did they ever fix the Orca's cargo scoop? I remember it being completely broken/useless when I first tried mine out.
