Thanks guys! It was a fun build.
Gene, good idea on using parts from a Me-262 but I'm not sure how much was in common from the two aircraft. From what I understand the Germans shipped the Japanese a working jet engine but the U-boat that was bringing blueprints for the engine and the Me-262 was sunk. So the Japanese took the engine they had apart, figured out how it worked and back-engineered their own models. Their first jet engines were smaller than the German ones so the Kikka ended up smaller. I think the only thing Nakajima had of the 262 were a few photos so they designed the Kikka to look simular but the insides were pretty much entirely different.
The oddest thing to me is like the 262 the Kikka was supposed to be a bomber. It was designed to carry one 500kg or 800kg bomb. I can't imagine what such a heavy weight would have done to the preformance of the aircraft.
Nakajima also designed a second fighter along the same lines, the Ki-201 Karya (Fire Dragon) which was slightly larger than the 262. The first Karyas were slanted to enter production in December 1945.
As far as I know there is no model available of the Karya (I guess one could modify a 262???) and this is the only model of the Kikka around in 1/48th, I am not sure about 1/72nd.
