Please Mission_bug, if you have one little time, make the franke HS-129A:
Maybe you can use the Si-204 engine and HS-129B model.
Henschel began detailed design work in January 1938, giving the new aircraft the designation P.46. The official designation Hs 129 followed in April, and the first visual mock-up was completed in May. A construction mock-up was ready by late July, and by August the design was finalised. Its weakest point was the Argus As 410A-0 twelve-cylinder inverted-vee air cooled engine, which didn’t provide enough power for the new aircraft. Argus had claimed that they would provide 465hp, but in use they only produced 430hp.
The Hs 129 V1 made its maiden flight on 26 May 1939. A number of changes were made after this first flight, before on 24 June the first prototype was damaged in a crash-landing.
By the autumn of 1939 both designs had been subjected to trails. Neither was particularly impressive - both suffered from a lack of power and poor visibility, but the Henschel machine cost a third less than the Focke-Wulf design, and so the RLM decided to place an order for the Hs 129.
Two more prototypes were built, both of which were delayed by shortages of key equipment. In the case of the V2 one propeller mechanism caused the first delay, but then an entire engine was taken to repair the V1, and the V2 didn't make its maiden flight until 30 November 1939. Even after both of the first prototypes were flying the test programme suffered from the unreliability of the engines. At the same time the weight of the aircraft was increasing, and its performance falling. The aircraft was particularly difficult to pull out of a dive, and on 5 January 1940 the V2 was destroyed when it failed to pull out of a dive.
The V3 didn't make its maiden flight until 2 April 1940. It was used to test the improved Argus As 410A-1 engine, which was still unreliable. This aircraft was damaged in June 1940, and was out of service until March 1941, leaving the V1 as the only flying prototype.

The A-0 aircraft went to Erprobungskommando 129, a special unit formed to bring the type into operational service. They had first seen the aircraft on 19 November 1940, when they criticised it for being under-powered and having very limited visibility. Henschel wanted to move onto a new larger aircraft, the P.76, but this would have caused unacceptable delays, and they were instead ordered to fit captured French Gnome & Rhône radial engines to a number of completed A-1 airframes to produce the first Hs 129B.
Hs 129A-0
The Hs 129A-0 was the first pre-production series of the aircraft. It was similar to the prototype, but had the 20mm MG FF cannon replaced by two belt-fed MG 151/20 cannons, which were much more effective. It retained the two 7.9mm MG 17 machine guns of the prototypes. It was powered by two Argus As 410A-1 engines, which finally provided the 465hp promised for the A-0 engines.
The main problem with the Hs 129A was the terrible armoured cockpit. In an attempt to reduce the amount of 75mm glass this was given two very small front windows, in a 'V' configuration, and surrounded by very heavy frames. The sides and roof of the cockpit were solid metal.
Hs 129A-1
By the summer of 1940 Henschel had received an order for 12 A-1 production aircraft, later increased to 16. Work on these machines began in June 1940, but they would never be completed as A-series aircraft. In September 1940 it was decided to abandon the A-1, and attempt to fit captured Gnome & Rhône engines to the almost-complete airframes, to produce the B-0.
