What about the speed limit on the Corsair?Not exactly. There's no ship-specific fudge factor for jump range like there is for shield strength or speed. Given the mass of the ship and the class of the FSD, the maximum jump range is determined for every ship based on, I'm sorry to say, maths.
It's extremely unlikely they'd break that convention just for one ship after a decade, especially since other ships before now have suffered quirky characteristics because of it – people don't realise that some ships have bad jump ranges because increasing the FSD class would've given them absurdly OP range instead.
The only granularity is in the mass, but if you're fixing cargo capacity your control over even the mass is somewhat limited.
They do have one freedom with the Panther-Clipper that they don't normally have: there's no Class 8 FSD, so in theory they can add it and give it any stats they want. I doubt they'd deviate from the established pattern of FSD stats by class, though. You can guess the Class 8 FSD stats by trend line and quickly see how absurd it'd be for the Panther-Clipper to carry an immense amount of cargo.
Add to all that, the person you're responding to details that thruster classes have maximum masses – and we already have Class 8 thrusters, so 5040t is the absolute maximum (and rules out Dirty/Clean which reduce it) and 3360t the 'optimal' for that class of thruster. Optimal isn't as much of an issue as they have fudge factors for speed and handling that let them get where they want to, but maximum is a hard line.
What about the Corsair's mass lock?
Is that math?
