So basically the new Desdi is a Pinto with a JATO booster welded to the boot?
: D More like a seagoing warship with a few Saturn-Vs strapped to it.
So Overtuned Drive Systems increase max speed but decrease maneuverability? De-orbiting space stations does need a lot of thrust, after all (from my KSP experience hehe)
It's a hullmod that increases all engine damage taken by 200%, and incurs 25% greater CR loss from hull damage during combat.
The Desdinova is much less maneuverable than before, but that's done through stat changes and ship system changes. It has much more inertia, but speed is mostly unchanged, meaning you will actually go further on one Arcjet charge than before, especially if you hold W and don't strafe.
The other main change is that it's way more durable. It gained 1500 hull and 100 armor.
Ramming can be quite viable with the Desdinova now due to its increased mass. You can push annoying ships out of the battle if you flame them out first, even a Hammerhead can be sent hurtling quite far away.
