It's a Knights of the Air Kit. I worked for them for about a year, back in the early eighties. I never saw any of the kits fly. The company was bought from a guy in California and was previuosly called World Jets. I might have done the glass work as that is my specialty. Good luck, with it as I said I never saw any of them fly. The two heavy blow moulded items are supposed to be the fuel tanks that went into the wings. I have heard of afew of the U-2's and the F-20 that have flown but never the Mig.
