Got to fly a 1936 Taylor J-2 Cub with one bladed Everal prop on Saturday:

He cranked with the nub end, pretty cool.

Lucky! Flying a 40 horse Cub with a single blade prop is on my bucket list.

Terrific video of a great aeroplane! It's good to see and hear some of these unusual engines and propellers still operational.
Thanks for posting.

Here's a good link to an article by the inventor:

So, is it free from vibration? Does it vibrate at one RPM more than another?

Wow! First time I see such a thing. How do you balance a prop like that? Does it hinder performance?

Got me a little worried there during the start.

He seemed to be a bit careless propping it just using the nubby end to turn it to the blade, almost like he did not ever expect it to start on the nubby end.

Gene's been propping airplanes for 70 years, he knows what he's doing. He was hamming it up a bit when it started, but that was all, it was hard starting and took a while to get going, had already worn out one propper.
Fouga23 if you look at the linked article it explains the balance and etc. Pretty ingenious. You can't tell any difference by flying it, but it is supposed to increase performance.
