Info
achikawa submitted a new proposal designed to meet the same requirements as the competitive Nakajima Ki-87. The new aircraft was a single-engined single-seat high-altitude fighter of conventional design with laminar-flow wings and featuring a pressure cabin mounted in the fuselage behind the wing trailing edges. The aircraft was to be powered by a fan-cooled turbosupercharged 2,400 hp Nakajima [Ha-44] 12 eighteen-cylinder radial, rated at 2,450 hp for take-off, 2,350 hp at 1,100 m (3,610 ft), 2,200 hp at 4,400 m (14,453 ft) and 2,040 hp at 11,000 m (36,090 ft), and driving a six-blade propeller, and the wing-mounted armament was to include two 30 mm (1.18 in) Ho-105 cannon and two 20 mm (0.79 in) Ho-5 cannon. The proposal was accepted by the Koku Hombu which ordered one static test airframe, three prototypes and eighteen pre-production aircraft under the designation Ki-94-II. The first Ki-94-II was scheduled for completion on 20 July, 1945, but eventually was completed two weeks behind schedule. The six-blade propeller planned for the Ki-94-II was not ready in time, and it was decided to begin testing of the first prototype on 18 August, 1945, by temporarily fitting a four-blade airscrew. A second prototype, intended to be fitted with the six-blade propeller, was under construction, but the end of the war prevented it from being completed, while the first aircraft was still being readied for its intended maiden flight three days later.

Hope this is OK, - here is my take on the RS Models 1/72 Tachikawa Ki-94-II. I also have the 1/72 resin kit of the Ki-94-I from A+V Models in the stash.
