SpeedyBee F405 Mini Flight Controller Stack board 3-6S 20x20mm Built-in Bluetooth with 35A BLHeli_S 4in1 ESC Board Support Wireless Tuning

love speedybee, Its a bit hard to solder since it's a mini board but i was able to manage, definitely should've gotten a normal size stack specially since this was my first time building but i was able to manage, just get a practice board or take your time and get a good soldering iron and flux! DO NOT underestimate having flux and a good soldering iron that gets to the right temp.i also love that speedybee has a wifi module on them so you don't need to use a USB and wirelessly connect to the their app that's basically betaflight

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.

The SpeedyBee F405 Mini is a solid option if you’re looking for a budget-friendly stack. The built-in Bluetooth makes wireless tuning super convenient, and it’s nice not having to plug in a USB every time. Performance is decent, and it does the job for smaller builds.That said, it’s not the most durable stack out there and feels more like an entry-level option. Good for the price, but if you want something long-lasting or heavy-duty, you may want to spend a bit more.

This is my go-to stack. It's reliable, hardy and space saving. I've run it on heavier 5in quads too, just upped the cap to a 50v to help with any spikes that might happen on high throttle. But for my 3 and 4in this is what I reach for a new build.

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!

I put this in my geprc baby croc 5" and paired with some 2105.5 2650kv hglrc specters and the thing rips. Didn't expect to get 100mph with a 1500mah 4s either..

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.
