Cinewhoops are funny machines that usually don’t function properly...or as you would want them to. Finding the right spec motor, props and ducts will dramatically improve performance. As of the pandemic of 2020, there are a couple ducted 3” props on the market. We found this specific prop to be particularly good on motors that can handle the load. 1506 motors will handle the prop but we really recommend an absolute minimum of 1508/1607 with this prop. On high load quads such as a cinewhoop and especially ducted quads, props tend to start feeling similar. Given it’s very aggressive nature, this prop has a bit more control feel than less aggressive options. Because it’s designed to be in a duct, it’s not really less efficient either depending on the duct being used. Maybe the most odd feature of this prop is that it feels surprisingly good as an open air 3” prop as well…

This prop is a fantastic match for the FPVCycle Cinewhoop motor coming soon

3” props

I like those best for cinewhoop

Great props but the 5 blade is better

Nothing wrong with these props except the 5 bladed now exists for ducts and I like that one exponentially better.

Quiet and powerful little prop.

I'm pretty sure these are the "standard" 3" ducted props. They are quiet, touch, and seem efficient enough. The first tests I did with the cloud 149 1300mah 4s I was getting a little over 8 minutes flight time. With a GoPro session that dropped to 5 minutes.

Duct prop goodness

It works nicely, not much to be said as I feel the ducts have more influence on the flying characteristics than the props themselves. With the stan ducts they're a tight fit. I was nervous that I might burn an ESC trying to "bed in" the props to the ducts as they had quite a bit of interference but on the 2203's it was fine. I'll look forward to trying other duct props but these are a solid first effort.
