I think the 400i is too slow for its size, Specifically it's acceleration forward, maneuvering, and reverse/stoping. When flying the 400i it feels like it's heavier than it actually is, it feels like a 600i it terms of maneuverability. The 400i supposed to be faster and more maneuverable than the constellation and corsair(what they said on ship talk) but it doesn't feel like it. I think the maneuverability of the ship should be buffed a bit.
