 The Vampire had a relatively good power/weight ratio and was reputedly quite maneuverable within the 400-500MPH range.Heavy use of the rudder was required at slower speeds, during which pilots had to be cautious during shallow turns to avoid stalls; this would be typically embarrassing rather than dangerous due to the relative ease of recovery, which was principally achieved via positive elevator application.At speeds in excess Mach 0.71, increasing levels of buffeting were encountered.
