Not sure how they could’ve made this little system any better. I’ve had consistent success with this tiny stack on 4 builds now. Very reliable and best price on the market. Speedybee is the Shiznit!

This was my first drone build. This package kicks butt. Be sure to run the capacitor where they recommend it. Very straight forward. I have purchased a few.

I've heard so many good things about this so I gave it a try. For some odd reason the fc would not power at all via the ESC harness - only unless I plugged it in via USB. I repair drones/flight controllers as a side gig and have never had this happen. Hopefully the replacement will work ok.EDIT: Replacement worked, but was super fiddly and would either not power the fc properly or spin certain motors. I found it was due to the wiring harness. I don't know what's wrong with it, but it took a lot of unplugging and replugging the harness to get everything to work finally. It seems secure but I'm a little worried that one crash will cause problems again.

Great stack with bluetooth features. Makes it easy to change settings without dragging a computer along.

Who needs F7 processes when 405 works just as good or not better. I really love the battery level lights on the side indicator and the LED pads on the corners for added lighting under your kwad. SD card slot on the FC for Blackbox log is genius. Speedybee is the only company that puts affordable product on the expensive hobby we love.

That was a big unfortunate setback especially when I was building a quad for a client of mine, & right when they received the quad it was great UNTIL, they turned it on, & attempted to go into beta flight. So, I got it replaced. Now all is well, still though it made my life a whole lot harder, & also upset a good client of mine.
