Am hearing that Diatone has gone out of business, too bad as I really like their products. This Mamba MK4 F405 mini is my favorite for light 3" builds so I got several to tide me over till something better comes out.

I’ve had so many issues with my mamba fc’s. They are cheap but it’s not worth it. There are better options on the market.

I have a couple Mamba ESCs that have been going strong almost 2 years now, hopefully their FCs have the same durability as their escs, only time will tell. I do like the build quality, if I were being picky it'd be nice if there was one more socket for RX....and if the pads were labeled. Updated without issue, usb-c is a plus. LED indicators is nice addition.
