I have not built those but I just finished Trumpeter's JS-3M. It was a nice build but there were a couple
minor inaccuracies and 2 issues with the instructions;
1) some items were illustrated upside down.
2) A couple parts shown in place were not identified.
Neither of these are major but caused some head scratching for a miniute.
Gather your resources/pics and, most important, have fun!
