Check the listing for details. Apollo 11 Saturn V F1 Rocket Engine Model, 1/48 Scale. Condition: New. Listed at 32.99 USD. Presented for your consideration, a model of the most powerful single-chamber rocket engine ever built: The mighty Rocketdyne F1 that sent men to the Moon atop the Saturn V. It took five of these, with 1 1/2 million pounds of thrust each, to get the Saturn V off the ground, with a fuel efficiency of four inches to the gallon!It's difficult to envision the size of these engines, so I've provided a tiny astronaut to make the scale more understandable. You can almost fit an entire Apollo Command Module into the nozzle skirt. Scale is 1/48. About 5" tall on it's stand. Fully assembled as shown. See the last picture for the basic specs. Made of 3D printed plastic, it will have visible layer lines. Includes stand, mini astronaut, and laser-etched label. Quarter for size comparison; not included.
