SpeedyBee F405 V4 Flight Controller Stack: 4 in 1 30x30 Stack with 55A ESC Board, Wireless Betaflight Setting, Black Box, Barometer for FPV

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

Been absolutely flawless. bluetooth support is a life saver when you forgot to save / apply a setting at home and just need a quick tweak. crashed soooo many times from being a noob and never had a single issue.

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
