Stumbled upon this issue when a Smaller, Lighter ship was manoeuvring SLOWER than its bigger counterpart, despite it being Longer, Significantly Wider, and being the same height. The ONLY difference between them is that the smaller ship has its core DIRECTLY at the front of the ship to use the core as the main camera through the ship's bridge. The Larger ship had its core more centred, and thus was able to pivot faster.
{F6888}
50 blocks front
{F6890}
25 blocks front, 25 back
{F6892}
40 front, 40 back.
Considering that people were given complete freedom on where to put their cores, it is wrong that they are being punished for placing them in certain locations, especially ones not centred to the ship. IE, Twin-Fuselage designs with the core on the left, and a gun in the right "pod" of a ship.
