Momentum and inertia are completely alien mechanics to starwars as a whole.
Starwars consistently makes the stupid fast and agile ships (fighters/interceptors) capable of slow sharp turns, when in reality they shouldnt ever be able to do that without applying huge g-forces on the pilot. People seem to think that stuff only applies in the atmosphere...no thats airflow (which affects HOW you turn, doesnt affect the effects of turning).
The super blazing fast ships shouldnt even have 1speeds technically, and a 2hard should be red if its there at all, but they have access to a 4bank/turn. Flipside, the freighters should be complete 1-2 speed access with ease, but they are outran in the blink of an eye. If you are moving slow, you can do a sharp turn, anybody that drives a CAR knows that. If you are whizzing at top speed, if you try to do anything more than a wide turn youre going to spin out of control (or in the air/space, flatspin and suffer huge g-forces).
This right here. Don't apply real world logic to star wars. It doesnt work. But we also have the X-wing and tie fighter games that show that the MF and firespray could keep up with the smaller ships just fine. So no reason to change large ships just cause of the real world thing.
Nah, not really. The X-Wing games portrait even X-Wings as slugfest and YT-1300 and YT-2000 are an exercise in patience. They have a max speed of iirc 75MGL (or 100 with all energy to the thrusters) while interceptors have a default max speed of 110 MGL and go up to iirc something around 140 to 160 mgl. Turn-rates are leaps away from each other too. And some of the Advanced experimental fighters even reach over 200 mgl. The Freighters are sluggish and can not just outrun TIE-Fighters. Superior flying at the other hand, having pilots who actually still navigate better in the dense superstructures of the Death Star or through asteroids while TIE-Academy pilots just crash into stuff. Now that is totally based on pilot skill. Lando flies successful into the Death Star despite being in a YT-1300 and not because he is in such a heavy ship. Though those two quad-laser cannon turrets should do plenty of extra damage too, like being able to fire your pwt 3 dice attack twice per turn. ,-)
Lando also do knock the Dish off of the top of the ship and Nien Nunb calls him on it. So yes he is an excellent pilot but it shows that it was difficult and I doubt they were flying at break neck speeds.
