The bf109 was a wonderful "boom n zoom" fighter
The definitive answer to the Spitfire stall.
The Daimler Benz engine used by the Bf109 as stated previously was Fuel injected. Thus when pushed into a dive resulting in negative g, the 109 would simply power away from any british fighter following. This was the standard German tactic to escape a persuing fighter & is well documented in most books written by pilots on both sides.
The Hurricane suffered from the same problem as the Spit by the way.
Due to the use of a carburettor on the Merlin engine, when the same manouver was attempted the fuel rose to the top of the floatbowl, resulting in temporary fuel starvation. The tactic used by Spitfire pilots to alleviate this was to roll the aircraft onto its back then push the plane into the dive in the inverted position, thus retaining positive g in the fuel system. In the heat of combat a difficult manouver that was rarely successfull. This was cured by the fitting of a Diafram in the floatbowl that kept the fuel in place and power on. To this day pilots flying the spitfire try to avoid negative G as a matter of course.
Cheers, Wolftone.
Ps. Haynes, the car & motorcycle workshop manual people do a very interesting 'workshop manual' covering the Spitfire. ISBN 976 84425 462 0. Library of Congress control no. 2007931175.
