I was curious about this as well; how does one engine drive contra rotating propellers? Unlike below where this cool machine has a separate engine for each prop:

The little information I have been able to find shows them to be fascinating in both design and execution, and once I get a bit more info, I’ll tell this story at a later date.

It would be interesting if someone could find and post a cross-section view of how a single engine drives the pair of Curtiss Electric contra-rotating blades.

But I guess it was a highly modified Curtiss P-36 making it an XP-42.

Which I thought looked like this:



The single model was tinkered with constantly in many ways, I'm sure.
For example the addition of the moveable horizontal stabilizer.

Here is one from the same era but not a Curtiss.. If anyone cares to chase there tail around lookin' for it...



The aircraft is 205 a few times already. Not shown from this view, though.

Looks like a variety of engines were tried out in the Vultee.

Also known as the model 48 with the same cooling problem that bedeviled the XP-42, initially.... it's all so cornfusing:
