The adoption of the Rolls-Royce Griffon engine provided the Spitfire with a significant increase in performance, but not without presenting Supermarine designers and pilots converting to the aircraft with a few challenges. Installation of the new engine in the existing Spitfire airframe required a redesign of both the front and rear sections of the aircraft and the use of a distinctive five bladed Rotol propeller. Pilots used to flying Merlin engined versions of the aircraft would find the Griffon turned in the propeller in the opposite direction and whilst the earlier aircraft tended to veer to the left on take-off, the Griffon powered machines would veer in the opposite direction if the pilot forgot and applied their usual corrective inputs, their first flight could be a particularly short and uncomfortable one.
