Commander Boof's BEAST on a Prop Dyno

I had to weigh it down with about 134 tons of lead because it keeps taking off without it. It even has rubber pads to add friction, yet it still keeps sliding. Because of this, I added a seat and made the entire frame tungsten, and built a kind of rollcage around the seat, so you can pilot this not-a-sled from inside it! Sure, its heavier than a train, but that's fine, right? RIGHT? Its got 12 propellers stacked inside each other at a 2:1 overdrive, and I added a clutch to help you get the massive prop assembly spinning. This is more akin to a motorjet than a propeller aircraft engine, given the propellers are stacked like the compressor stage of a turbine engine, just far, far larger than any jet engine ever made. Seriously though, Commander Boof made a meaty engine, "props" to them, eh? Eh? That was a good joke, come on! I thought it was funny!
