SpeedyBee F405 V4 BLS 3-6S 30x30 Stack/Combo (F405 FC / 8Bit 55A 4in1 ESC)

It is surprisingly durable - crashed my 5 inch drone and afterwards one of the motors started to twitch. I thought that it was the end of the esc, but it turned out to be a dead motor.

Just built a new 5in with this stack and I couldn't be happier with it. the price also makes it a no brainer to use.

I use these in my apex freestyle builds. They are conveniently laid out for the components to be soldered to. And in my experience I’ve had no issues at all. And I run them hard. Rain, snow, (though I don’t recommend it). Never had one fail from crashing or other wise. Esc is top notch as well, hundreds of full throttle rips for several seconds. And at the price? It’s the best.

Have this stack on 2 of my 5” setups.

I have a few 60 Amp Stacks and these things are awesome! 🤯They are very durable and perform amazingly! Love the Bluetooth app too, for quick modifications in the field! I highly recommend these among many others. Just watch out for salt water, lol! This is the one quad I turned into a Cormarant! Don't do that! 🤣

The price is great for a budget build, the issues from the v3 were resolved. No problems with the fc so far, but a tiny component on the esc broke somehow... I asked the speedybee support about it, they couldn't tell me the name of the part, so I have to buy a new one, won't be a speedybee this time...

Edit: heard about from issues with the esc from others aswell, on a budget you can get the fc but I dont recommend the esc

Easy to solder, good features and price.

And one day the built in Bluetooth might save your day.
