SpeedyBee F405 Mini BLS Stack w/ 35A 3-6S BLHeli_S 4in1 ESC - 20x20mm

Just works!

Used mine in a 3 inch freestyle build, the only thing that I'm missing is a couple more LED pins

I used the SpeedyBee F4 Mini on my first build, a Grinderino. I am still very "green" in the hobby, and can't say 100% how it flies to others. But for me it's awesome. it has sooo much more power and response than any of the other quads I fly. I was lucky enough to get this stateside, before the prices went up earlier this year. And honestly glad I snagged two😅 I will definitely be using another in Grinderino #2! The only negative which isn't with the board itself really. Is that the pads are pretty small and it takes patients and precision when soldering it up. I used a SpeedyBee practice board right before soldering this, just to be sure I didn't make mistakes 😁
