I am not that interested in player designed ships myself, and apparently I am not the only one, otherwise people would surely have responded to your threads.
I have posted on several occasions about what I perceive to be gaps in the ship lineup.
For example I think that the Empire needs a medium pad multipurpose ship of similar capacity as the Python.
I also have commented on one or two ship designs and commented on what I don't like about them.
For example I think that the Clipper bridge is disproportionately huge and distorts the perception of the ship's size.
I also think that the bridge of the Cutter should have been moved to the middle of the ship on top of the hull.
And last but not least I think that the Vulture's pilot's chair is placed too low in the cockpit which causes visibility issues to the left and right. This is completely unnecessary, because the dome of the Vulture's cockpit is so huge that there is enough room to move the pilot at least one meter higher up in the cockpit.
So to make a long story short: I am not interested in new ships designed by players, but I would love to redesign a few serious flaws in existing designs.
