love these props

Works great

Full disclosure: Gemfan is one of our team sponsors, but I found and bought these on my own and this is entirely my own opinion. I got them for a 5" ultralight build with 2004 motors. I actually had some concerns that even though the build was lighter, a thin prop with a shallow pitch wasn't going to give me the speed of my usual 5146.5s. But I was dead wrong about that. These props bring a surprising amount of power and durability. Especially for a T-mount. Nonetheless they are paper thin and super light. As a result even my 2004 motors spool up almost instantly. Giving the drone both top speed, but also an incredible quickness. My FPV image gets blurry when I punch them hard. After a few hard flights the blades take a permanent curve from their own vortex. So you know they're working. Definitely the best prop in its class for ultralight builds. I've stocked them for the rest of the season. Buy them with confidence.
