Papercraft working V12 engine cranks, lights up

Mack sez, "Is your papercraft-fu strong enough to tackle the 595-page manual that tells you how to build this V12 engine model with moving cranks and pistons and LEDs that "fire" to indicate an ignition or exhaust cycle?

Gather your strength, grasshopper. I can tell by your bug-eyed gape that you are not yet ready."
