I haven't try to fly or test with my CF props, still waiting my new QR plates from Dronehi.re company same as LP plates and cheaper.
I use the Dronehi.re plates. They work fine, but I do not like the way they operated their company (the testimonials on their website are 100% fake and they are terrible at managing customer information, for example, they once sent out a mass email without BCC'ing the recipients so I basically have a list of all their customers now).
How do you like with your set up on 1448? Stable or responsive>
I love it. I have some issues sometimes with the prop hitting my X5 mount because of the length but no issues so far (over 250+ flights).
Very stable, quieter, higher top speed and acceleration. Responsiveness, I'm not too sure, it feels the same as the stock props to me.
Just be even more careful now because these blades WILL hurt someone really bad when spinning.
