SpeedyBee F405 V4 Flight Controller Stack: 30x30 Stack with 4in1 55A ESC Board, Wireless Betaflight Configuration, Blackbox, Barometer for FPV

It's fairly easy to learn. We've come a long way since the KK.2 boards.

I’m really liking the SpeedyBee f405v4. It’s easy to setup. I’m adding to this review because the ESC turned out to be defective. One of the four motors would run intermittently. I contacted Amazon support and they’re sending me a new stack. Great customer service! I hate having to desolder all my work but it’s worth it.

Bought this as a budget friendly Stack for a 5” 6S drone. Got it all set up and went to fly it and sounded like I had a dead motor. Got motor replaced and issue persisted. I received a bad ESC. Got the Stack replaced through Amazon and installed the new one, which is the pictures in the review. I left no room for error and this failed me yet again 2 times in a row. Had the drone up for about 10 seconds, heard the same noise I had before and boom. A 3ft long flame came out the bottom of the drone and instantly followed with sparks and fumes until I could get my battery unplugged. Fried pretty much everything on my drone aside from my motors. Brand new Caddx Vista gone, brand new RP2 gone and brand new Stack gone. Ruined a lot of money I put into this build. Not happy with this product and I do not recommend it at all. Go with a mamba stack if looking for a stack. Never had issues with them. Would give 0 stars if I could. It doesn’t even deserve 1

I used this on my first custom built fpv drone because it was “plug and play” with the DJI O3 air unit. The price on Amazon is slightly higher than the price on the SpeedyBee website, but the delivery time is like a month on the website so I’d recommend you buy from Amazon for the much faster shipping

I am on my second board and the SMD components keep blowing. It could be from a small short in a crash but is not durable whatsoever. They gave me a new one for free but it did the same thing. If it were me, I would go with someone else. Although, when the board works, it's amazing. (Just is not durable)

Love this product have them in all my quads. Did receive a messed up one but that's does happen you will get that with any product.For the price and how quick you get it you can't go wrong

Many crashes. Still working

Flight controllers are awesome especially for the price but the speed controllers are hit or miss. Sometimes you get a really good one that will last years sometimes you tap a stick with a prop and a fet explodes.
