The first job on this kit is to decide what options you're going to fit. Booster rockets, undercarriage, hung from a bomber, etc. Meng have thoughtfully given each option half depth holes which you can drill out from the inside.

I'm fitting one with the booster rockets sitting on a dolly and one with wheels. I've decided to make both models at the same time, but probably only enter one in the competition. One is going to be a well worn Japanese fighter, and the other a 'what if' type aircraft, mainly to amuse Jess. See if you can guess the what if scheme before I apply paint that will give it away
One thing I did notice about the kit. This plane was never built. It was a development of the Ku-2 & Ku-3 swept wing, tailless gliders that the Japs were developing, but the project was cancelled before the powered version was built. It seems to be fairly well documented that it was supposed to be powered by a ram jet, possibly based on the HeS 001. I can't find any pictures of that particular engine. However, the kit has turbine vanes on the intake and exhaust on the engine. That is clearly wrong as a ram jet doesn't have any vanes.
I did think about leaving the vanes off, but then the cockpit would show through the intake. Clearly the drawings that were found needed a bit more development work as the pilots feet were dangling in the engine

Anyway, plan B is to cut the vanes off the intake disc, and then paint it matt black. I'll leave the exhaust fan off completely and paint the inside of the fuz matt black too. I think that will look slightly more authentic.
