3DR Solo Built-in Nut Upgrade Propellers - MR SL 10x4.5 Set x4 Black

I placed the order and it was here before I knew it.

If you have a Chroma Blade 4k and need propellers, these not only 100% fit, they outperform the originals. So happy to be back in the air again.

These props... They RULE. I started using them with a 3DR Solo (which comes with its own props) and upgraded to these. I can see a difference in power consumption (which I guess owes to their greater pitch), I can hear a difference in motor RPM, and the copter generally tends to handle better, kind of like a car does with upgraded tires. I recommend them to anyone asking, since the benefits are obvious.
