Official: the next model that I will master for Fantastic Plastic is the Project Pluto nuclear ramjet cruise missile. The next model was *supposed* to be the “2001” Space Station V, but I’m separated from my references for that. But the Pluto stuff I have on hand.
Currently undetermined is the scale. 1/72 is the obvious choice, but 1/48 might be possible as well. Some measure of “cutaway model” will be inevitable, due to the wide open nature of the inlet and nozzle; a full cutaway with all the innards is unlikely, but possible at larger scales. If you have a preference, leave a comment.
