To illustrate the controlability issues of the Griffon engined Spitfires with the small tail surfaces.

From the Pilots Notes of the Mark XIV and XIX, Griffon 65 or 66 engines.

Para 49 (i)

"When ever possible open the throttle slowly up to +7lb/sq. in boost only. This is important as there is a strong tendency to swing to the right and to crab in the initial stages of the take off run. If much power is used tyre wear is severe. +12lb/sq. in boost may be used at heavy load and should in any case be used on becoming airborne to minimise the possibility of lead fouling of the sparking plugs, but +7lb/sq. in boost is suffficient for a normal take off"
