Rounding the Last Turn?

Progress is happening fast now, with the whole Aircraft Department pitching in. Plus, our engine-making friends in Ohio have hit a major milestone by starting up the engine for the first time! Here’s a video of big moment… this is a sound that no one has heard for decades!

That massive engine tops 478 cubic inches, weighs nearly 300 pounds, and produces a whopping… 75 horsepower. Yes, apparently technology marched on and left the poor Roberts Engine behind. For a modern comparison, the 2013 Corvette Z06 has a 400-pound, 427ci engine that produces over 500hp! But hey, in 1914, this was the cutting edge.

Keep in mind this engine was built from scratch! Casting, milling… we had no existing engine, only a 4-cylinder reference model. Steve Littin and his team really produced a work of art! Have a look:
