Henschel Hs P.75
This 1941 aircraft design was to be a possible successor to the Messerschmitt Bf 110 heavy fighter. Although of a unusual configuration for that time, there were advantages (and disadvantages) to its rear wing/forward canard construction.
The Hs P.75 featured a tapered fuselage, with the slightly swept-back wings being mounted mid-fuselage and set back to the rear of the aircraft. The widened fuselage was designed to house the Daimler Benz DB 610 engine, which were two DB 605 engines joined side-by-side, just aft of the cockpit. These were the same engines that the Heinkel He 177 used, and were found to be prone to overheating and catching fire. Due to this development, they were changed in 1942 to the liquid-cooled, 24 cylinder Daimler Benz DB 613 engines (two coupled DB 603s) that produced 3500 horsepower. Both engine configurations were to drive contrarotating propellers (to offset tourque) of a 3.2m (10' 6") diameter via an extension shaft. There were a pair of swept-back canards located on the nose of the aircraft, that were to serve the purpose of elevators. The vertical tail unit was mounted beneath the fuselage, so that it could act as a tail bumper upon takeoff so that the propellers would not strike the ground. Since the propellers were located at the rear in a pusher configuration, a tricycle landing gear arrangement was chosen. Fuel was contained in three tanks, one in each wing and one behind the cockpit. A single pilot sat in the cockpit which was located about midway along the fuselage, and four Mk 108 30mm cannons were mounted in the nose.
The advantages of the pusher propeller/forward canard design was that it opened up the pilot's view, plus the weapons installation was much simplified and could be concentrated. The disadvantages would be engine cooling plus an ejecction system or propeller jettison would have to be designed for the pilot to safely exit the plane in case of an emergency.
This basic design was realized in several WWII aircraft designs. Although good results were obtained with a model in the windtunnel, this design was not followed up.

The Curtiss-Wright XP-55 Ascender (company designation CW-24) is a 1940s United States prototype fighter aircraft built by Curtiss-Wright. Along with the Vultee XP-54 and Northrop XP-56, it resulted from United States Army Air Corps proposal R-40C issued on 27 November 1939 for aircraft with improved performance, armament, and pilot visibility over existing fighters; it specifically allowed for unconventional aircraft designs. An unusual design for its time, it had a canard configuration, a rear-mounted engine, swept wings, and two vertical tails. Because of its pusher design, it was sarcastically referred to as the "Ass-ender". Like the XP-54, the Ascender was designed for the Pratt & Whitney X-1800 engine, but was re-designed after that engine project was canceled. It was also the first Curtiss fighter aircraft to use tricycle landing gear.

Sai Ambrosini SS.4
The SS.4 was a single-seat fighter of all-metal construction with a canard configuration wing with twin fins mounted on the wing trailing edges, retractable tricycle undercarriage and short fuselage with rear-mounted engine driving a pusher propeller.
The pilot was accommodated in an enclosed cockpit in the centre of the fuselage forward of the two fuel tanks and aft of the armament in the nose. Visibility from the cockpit was excellent to the sides and front, but restricted to the rear by the large main wing, engine and large twin fins positioned at approximately the half-span position. Flying controls consisted of elevators on the trailing edges of the canard fore-plane controlling pitch, rudders on the large fins controlling yaw and ailerons on the main wings to control roll. Pitch trim was set by adjusting a trim tab on the starboard elevator.
The moderately swept, tapered, high aspect ratio wings had no sweep on the trailing edge and a cut back to give clearance for the propeller, with the large fins with rudders extending past the trailing edge at the ends of the cut-backs, to ensure enough moment to give adequate control and stability. The delta fore-plane was of low aspect ratio with the elevators sited below the trailing edge similar to the method used by contemporary Junkers aircraft like the Junkers Ju 87.
The engine was a powerful liquid-cooled Isotta-Fraschini Asso XI R.C.40 engine capable of 960 hp (720 kW) driving a three-bladed metal propeller. The engine was cooled by two radiators either side of the fuselage in ducts just behind the cockpit. Fuel for the engine was housed in two fuel tanks located mid-fuselage along with an oil tank.
Armament was to be two 20 mm (0.787 in) cannon and one 30 mm (1.181 in) cannon, clustered in the nose.

Canard designs are my love and joy, and I wish IL-2s inventory of them would rise even further! within the BAT I have currently the J7W and the Paulus Dragonfly canard designs, but I wish for these to be added within the modpack/game! Do tell me what you think about this and if someone would make them, I'd be forever grateful!
