Currently the Xi'an, at next to no speed, has barely any maneuverability which just isn't right considering the dual fans providing rotation force when using Q/E controls.

More importantly, when at full speed, stopping the Xi'an is an exercise in frustration due to the lack of control surfaces preventing high-speed maneuverability. Why on earth weren't they included in the tail section which is very capable of fitting them? At least include an airbrake. Please.

Additionally, when hovering, if you zero the thrust the vehicle suddenly jars. Uncertain if this is a bug or part of feature.
