Well, one of the places you have gotten to is the stop the PE and paint, or try and paint around fragile PE?
Because it's Hiryu, you do have an advanatace fr not having a lot of galleris ans serach light platforms with Chestnut linoleum decks.
However, becasue it's Hiryu, you are facing the need to mask and paint the disruptive deck pattern. Which is likely death to installed rails given the number of colors required.
But, there is a very real possibility you need a different deck color than the sides--thhis is a bugabear most of the time. As you either have to brush paint or mask
And "complete" 1/700 aircraft--LOL. They now come as microscopic kits unto themselves. Separate landing gear, PE to make canopy frames, struts, nona-decals, the works.
Do not even browse shapewaps for the AA fit, they will exist. And they will tease you with their teen, microscopic, beauty. Or for crew, for that matter, which will come in blocks of a 50 or a hundred at 1/700, and far easier to deal with than PE crew.
It's a rabbit hole. To Alice's Looking Glass, and the Red Queenawaits within and a Cheshire cat laughing at you the whole time.
