this is the Falcon Mk II, it is an upgrade from the Mk I version in the following ways: 
Maneuverability, the maneuverability has been improved by adding surface area to the pitch control surfaces.
 theres also a wing infront of the inlets, you could put a pitch control surface there, but i havent seen its maneuverability improve by doing that.
