The LAPCAT M4 is a study by LAPCAT (Long-Term Advanced Propulsion Concepts and Technologies) for a 337-foot-long hypersonic commercial aircraft created as a proof of concept for new engine types, as far as I know, this is the only physical model in existence of this aircraft, I guess I get a world record now >:D

FINALLY!!! ANOTHER 1:400 SCALE MODEL!!!! this model is, like my other models at 1:400 scale, unlike my other models, however, requires assembly, I would use superglue to glue the 2 pieces together, this model I painted since I didn't have the light blue filament I needed, I just painted it, though admittedly, I do have normal blue, just darker, feel free to use AMS (I actually encourage anybody who has the system to use it), I encourage you to add pictures of your model if you printed it, as I would love to see how your turned out! also, mentioned this earlier, but as far as I know, this is the only physical model of this aircraft in existence, we should give more light to these kinds of planes that barely get talked about and don't even exist in real life! :D thank you for taking time out of your day to read this silly little message :)
