I am betting Liberty is speed 3 because of CrackenI think it may be faster but less maneuverable. It has more engines.
I don't know. I can't really see the back of the Liberty...
... and as it is, the MC80 Home one has a butt-ton of Engines for its Speed 2....
You only need one engine to reach Speed 3. This is known.
Won't affect it anyway, Cracken is small or medium only.
