 According to Mason, the controls of the Vampire were considered to be relatively light and sensitive, employing an effective elevator arrangement that enabled generous acceleration from relatively little control inputs along with highly balanced ailerons that could achieve high rates of roll.In comparison to the elevator and ailerons, the rudder required more vigorous actuation in order to achieve meaningful effect.Pilots converting from piston-engined types would find themselves having to adapt to the slower acceleration of turbojet engines and the corresponding need to moderate rapid throttle movements to avoid instigating a compressor stall.
