A Fully Charged episode on Electroflight, an early-stage project to build a fully electric racing plane that can exceed 300 mph. It features two motors driving contra-rotating propellers.
HN points to it in electric aviation threads for how small electric motors enable contra-rotating props.

If you're interested in the electrification of flight check out this episode of Fully Charged: ▶ this video Its kindof like a "roadster" for the sky. I was really impressed by the contra-rotating prop opportunity that becomes possible because of how small electric engines are (for their power).
> There have been several battery-powered human carrying aircraft. Most are scaled-up quadcopters Umm.. wat? Afaik most serious attempts for electric (battery-powered) aircraft have been fairly conventional fixed-wing designs. As you seem to like youtube videos, here are couple: link from Airbus link Siemens link Pipistrel ▶ this video Electroflight I think the Pipistrel one is actually already shipping today.
The most recent episode if "fully charged" was also about a prototype electric acrobatic plane: ▶ this video It reminded me of Tesla's evolution, where they found a niche where they can apply the benefits of electrics and rethink some basic elements of the platform most notably in the double propellers.
The most recent episode of Fully Charged [1] looked at a 100% electric racing plane currently in development that uses two electric motors to drive two counter rotating propellers at the front of the aircraft. [1] ▶ this video
