Using these on my 2.5v tricopter. Any ground contact results in instant snaped prop.
This would be ok at 20cents a prop not a $1.20 a prop.

lightweight and easy to mount. I had to drill the center hole out to 6mm, still enough plastic left for my prop adapters to mount. be careful, even a simple blade of grass will shatter one of these.

These props are terrible.
They are full of casting imperfections, flex terribly and are badly balanced. They feel like they would break with light use. If you could even get them to fly reliably. Avoid.
