The Me109E relied heavily on its cannon armament, 2 x 20mm cannon in each wing, secondary armament was 2 x 7.92mm machine guns above the engine. The ammunition for the 109E's cannons was limited to only 60 rounds per gun - so the pilot needed to be accurate to make his rounds count, obviously a hit by a cannon shell was more devastating than the .303 browning bullet fired by the 8-gun spits and hurricanes, but the respective total armaments of the 109 and the Spit pretty much balanced each other at the time.
Anton, I don't want to labour this point for much longer as I very much respect the work you and your colleagues have put in bringing this sim to the console market , and believe you me I'll be spending many as many hours in the Fw-190 as the Spitfire variants, but is there any chance of the Spit Mk1 being added as a DLC in the future ? A Battle of Britain campaign really needs the right key aircraft
