Group 8 for forward firing .303 brownings (yes, xml modded bullet mass, fire rate, velocity, and calibre)
Group 1 for rear Vickers K machine gun (7 second reload after 60 rounds fired), and camera 2 acts as rear gunner sight.
This is a replica of the Blackburn Skua, sorry about the lack of paint job, but I simply don't have the skill and would love to see a successor with camo. however, I have used xml modding to get more realistic performance and gun fire rates and reloads on the rear gun. The speed is approximately 5mph faster than the real version, but everything else is the same. Thanks to Skua for the excellent roundels, and to Mrwhiskers85 for the cockpit section, taken from his excellent Westland Lysander (predecessor to this aircraft).

Now here is some background info taken from Wikipedia

The Blackburn B-24 Skua was a carrier-based low-wing, two-seater, single-radial engine aircraft operated by the British Fleet Air Arm which combined the functions of a dive bomber and fighter. It was designed in the mid-1930s and saw service in the early part of the Second World War. It took its name from the seabird.

Skuas were credited with the first confirmed "kill" by British aircraft during the Second World War: a Dornier Do 18 flying boat was shot down over the North Sea on 26 September 1939, by three Skuas of 803 Naval Air Squadron, flying from the aircraft carrier HMS Ark Royal. An earlier victory by a Fairey Battle on 20 September 1939 over Aachen, was later confirmed by French sources. On 10 April 1940, 16 Skuas of 800 and 803 NAS led by Lieutenant Commander William Lucy, flying from RNAS Hatston in the Orkney Islands, sank the German cruiser Königsberg in Bergen harbour during Operation Weserübung, the German invasion of Norway.
This was the first major warship ever to be sunk by dive bombing, indeed the first major warship ever sunk in war by air attack.
