Speedybee F405 V4 Flight Stack - $70 For All Of This!

[@Joeyzoom]

I've been flying the v3 all summer and have been enjoying it. I'm glad SpeedyBee continues to innovate and produce quality products for a very reasonable price. I know others have mentioned concerns about their ESCs catching fire, but I've never had an issue. Cheers 🍻

[@MAGAblackNeegeering]

Mine caught fire today. Very disappointed. I’ve built plenty of quads. No reason for it.

[@chriscflint]

Just ordered one from your link and free shipping to Australia, wow. I have the V3 on another 7"build and it is fantastic and very well made, thanks.

[@testpilotian3188]

Someone at Speedybee has a sense of humour with that price…

[@Loki_Morningstar666]

Speedy Bee has the F4 V3 on sale on their website to clearance them out so it would be a good time to pick one up cheap for a spare or a budget build

[@MTB_FPV]

I've got 2 of these in my bando bashers and they've been flawless.

[@circlearoundtheworld]

using the f405 v3 as my first drone , so far so good!

[@MCsCreations]

Fantastic review, Ian! Thanks!!! 😃 SpeedyBee is just killing it lately! Really valuable hardware, even for wings!!! Stay safe there with your family! 🖖😊

[@AerialWaviator]

Great overview Ian. Regarding video title, I'd suggest using "F405" vs. "F4", as may storefronts use "F4" to refer to F411 flight controllers. F411's lack UARTs, working memory, etc compared to F405's. While Speedybee doesn't list Ardupilot capability on it's website, the v3 is listed as compatible hardware on ArduPilot/ArduCopter docs/wiki. Having bario/compass support makes this F405 stack. It would be nice if Speedybee actually stated ArduPilot compatibility (forthcoming) for this F405 v4. Perhaps this FC stack could be inspiration for your next arducopter build, as we also have a number of HD video options available going into 2024?

[@MadRC]

Thanks and done.

I have gotten 5 of these since August each ordered separatedly , but the wing edition which was about 38€ incl. 19% VAT and shipping. Great value, great packaging and full set of accessories which means even the presoldered cables. I like them a lot and prefer those over the Matek fixed wing F405 - the old one and even the new one cause Matek asks now for the new edition (they had not delivered FC for over 2 years) over 58€ China is not under INFLATION, but 5% deflation so their costs are decreasing and that allowed SpeedyBee to go this way for new products. Matek is just taking what they think the people in the west under inflation pressure should be willing to pay after they had not delivered for over 2 years. Great experience so far. At least for the fixed wing edition. But be aware they are expecting export sanctions for drones and even flight controllers where it is not clear if this will only hit the western countries cause I had asked about that topic. We usually need 20 each year for holiday camps and therefore had to fill up our stock so we avoided to order 5 at once to not be hit by sanctions and ordered every week one after the previous had been shipped. With 4 guys and 5 weeks we have gotten the 20 we need. Shipping was about 5 days once you got the dhl number (EU), fastest shipping in the whole industry from a manufacturer or vendor in China that has no EU warehouse. Extraordinary fast and reliable.

[@cinemoriahFPV]

You didn't buy any of these they just released this version.....

[@pottyputter05]

​@hersheyfpv3501 ok, you aren't that stupid, right?

[@neilfpv]

I have the SpeedyBee F7 V3 flight controller. It's amazing! Recently I bought SpeedyBee F405 V3 stack. I have a recent upload about it which I did some review and LOS. It's an amazing stack! Great video review Mads Tech!

[@michaelwhouse46]

Well that explains why they"ve been selling the f405 v3 for $10 off. I stocked up and bought 3 of those and 3 of the f4 mini. A guy can never have too many stacks. I've been using the v3 in 4 different quads for quite a while and love them. For the $$$ you can't beat them, and with Bluejay not only do you get bidirectional dshot, but cool start up tunes.

[@h2o40fpv]

Wow this speedybee its really doing it amazing really there is no more to look around 😊

[@Chillin-fpv]

I hope the f7 v4 isn't far behind. I love my speedybee stacks. Just so easy to work on. Everything is clearly labeled. Just so good!

[@cinemoriahFPV]

F405 is actually superior in some ways more like more flash memory than F722

[@Chillin-fpv]

No... no it's not.. the only thing I can think of it being better would be the price.

[@AerialWaviator]

While F722 can have higher clock speeds, it has less working memory, and fewer i/o capabilities. Features that mater if used for a purpose other than racing, or a freestyle build, particularly if using a FC OS like INAV, or Ardupilot that have larger memory footprint and offer additional features. F405's have a large number of UART's, i/o protocols and PWM channels.

[@Chillin-fpv]

@@AerialWaviator are you just guessing? Cuz a few Google searches will give you the correct information..

[@Chillin-fpv]

The only thing the 405 has over the f7 is more memory that's it.

[@Halfrightfox]

I have no idea how they're making a profit on this. $70 is fantastic

[@rcfreakamit]

Great review, looks nice. Sadly I couldn't see in their documentation whether or not the 9V BEC (aka VTX) is ON/OFF switchable via an AUX channel, as some other stacks (not too many) do. IMHO this is a really nice feature to have.

[@MadRC]

Sadly no it’s not got that.

[@flat-earther]

Speedybee wrote in the product page _The F405 V3 FC faced compatibility issues with certain microSD cards, with a few even occasionally affecting the stable OSD display._ But doesn't the v3 have the issue with any microSD card because the OSD and blackbox shares same SPI bus? Do you think speedybee is dishonest here, not saying the truth, downplaying the issue and not admitting they made a design flaw in the v3 board?

[@divingfalconfpv4602]

what barometer? mine isnt working well. think betaflight didnt find it right with auto

[@skshahed9185]

how can i change the defult 24khz pwm frequency to 48khz

[@gloriousquads]

I love it. I just dont like the heatsink on escs much. It really limits the motor wiring options for neat look. Otherwise Im happy with both F7 and F4 v3 of Speedybee products

[@sahilmansoori3511]

Will it fly fixed wing if flashed with inav?

[@erikvf7]

Hello Ian! I heard some people had some issues with the O3 shutting down during flights when powered directly from the onboard BEC of this FC. Do you know anything about it?

[@breckfreeride]

Would it work in a wing with a single motor?

[@Ipsissimus]

Can I use this to build a Cinewhoop?

[@redreefbud]

Great video 😁 very informative. Keep them coming. I would love to test some stuff if you want to send it my way 😁 just got integra goggles and 03 unit. Speedybee master 5 v2 frame. Supernova 2207 1980kv motors, gemfan 51466v2 props (bumblebee yellow) 😁

[@Picit13]

will this work ok for a semi long range 10" running a 6S? I am just getting into FPV after years of box-drones, I am running a boxer radio and 10" frame but that is as far as I am so far.

[@ArshaansEdits]

Hi! I actually need a suggestion, should i go with the Speedybee F405 v4 or the Speedybee F7 v3 flight controller

[@MadRC]

Either will be fine. The F4 is a great controller overall

[@redreefbud]

I started with the speedybee f7v3. My first diy drone. Built a master 5 v2 with supernova motors. Hooked up the f7 stack and it would not recognize receiver. Tried 2 different brand new ones. Radiomaster rp3 to go with my new boxer radio. And then a happymodel diversity dual antenna. Anyways couldn't get it to work so ordered a f4 v4 today 😁 hoping i can get that to work. Do you think the 2 esc are interchangeable? I think something was off with the firmware of f7 and superbee app. Idk. I tried to flash firmware or changed msp and now no lights or anything. Something does beep when powered on but not like before. Think the flight controller is gone. Hence the f4 😉 hoping v4 will work better with app. Any tips or things i should do? 😁

[@cleitinFPV]

can it fit in iflight evoque frame?

[@MadRC]

Yes absolutely

[@muchthump]

Wonder how long it will take to comebout with the 20x20 version. Appreciate the beefed up esc. That was definitely in need of an update.

[@grandpa_stanley7813]

Well the 20x20 f405 one just came out like a month ago, it looks kinda sick

[@AerialWaviator]

From last month, Ian looked at this 20x20 with a $60 price tag. kzbin.info/www/bejne/h6i3h2eAhblkfrM

[@ebjamville]

Thanks If only it had a can bus - for relatively cheap RTK.

[@gabrielnunes159]

Hello my friend! Thanks for your great video! One question: I have the F405 V3 and try to use blackbox with SDCard but no sucess. I tried to change the settings, use BF 4.4.X, 4.3.X, 4.2.X but nothing worked... I tried both SDHC 8GB and SDXC 64 GB... Format them to FAT32 with 4096, 8192, and all kb possible... I also did a partision with only 2GB on the cards but no sucess... Any ideia what may be happening, and how I can fix it and finally use the blackbox? Thank you so much in advance, BR.

[@husseinalsweid5062]

Hi, i sill have the issue with the SD card. or should i use the from Speedybee recomanded 8GB SD card? does anyone has the same issue and can help me here please?

[@leonardocastaneda904]

a newbie here, whats bidirectional d-shot?

[@lowdashfpv]

DSHOT is the protocol that the flight controller and ESCs use to communicate. It used to be one-way, with the FC sending commands to the ESC and that was it. Bidirectional DSHOT allows the ESC to now send telemetry back to the FC as well. It helps with some Betaflight filters and such. In regular BLHeli firmware, bidirectional DSHOT isn't supported. It's only in BLHeli32, which mandates faster, 32bit processors on the ESCs themselves instead of the 8 bit ones like on this stack. IIRC, the BLHeli devs said it couldn't be done because of resource constraints on the 8bit processors. After a while, the BlueJay (and another, JESC, I think), came out and implemented it, proving it could. Some manufacturers still ship BLHeli on their ESCs, but most can simply be reflashed to BlueJay to get that functionality.

[@TheDarkstar826]

They need to fix this board again. The cutout for the fpv camera is not compatible on some frames. For examples: Apex EVO 5" FPV Fram, Steele 5 or Similar style. Issues: 1) You can't have press nuts underneath the board because the 8 pins connector(Esc) is landing on top of the press nuts. 2) The stack height is wrong. the website said 16.1mm. You also need to add the USB C height as well. if you have press nuts underneath the board and your frame usable space is 21mm(H). You are screw. All they need to do is fix the 8 pins connector. They need to move it forward. That's all. lol

[@artifixprime]

Is there a reason why they wouldn't ship with Bluejay? I think JHEMCU do this with some of their AIOs

[@MadRC]

Honestly I don’t know. It is odd.

[@ShadowOppsRC]

5 inch i bought used and has dead fc is getting this stack.

[@MekataniDrone]

I hope the V4 works good on INAV. V3 are not so good on INAV. Betaflight build is good tho

[@Fly_High_FPV]

I'm hearing alot of issues with that gyro...4 people today mentioned problems

[@markitzero7408]

What kinda issues? I have 3.

[@Fly_High_FPV]

@@markitzero7408 tuning problems

[@MrLootshoot]

@@markitzero7408 working for me also

[@cinemoriahFPV]

Unless they did something magical, the ICM42688P gyro has been historically garbage for use in flight controllers... Im skeptical and waiting for BBL data...

[@stefansekej3047]

I was just thinking the same thing. Didnt JB and blunty butcher that gyro?

[@MadRC]

It needs a good clean power source like this FC has and there has been tweaks to the filtering in BF as I understand it. As such today it’s deemed one of the best option.

[@Fly_High_FPV]

Confirmed, have heard 4 reports today of pilots with issues with this gyro

[@cinemoriahFPV]

​@@Fly_High_FPVThat's what I suspected 😔

[@cinemoriahFPV]

​@@MadRCI disagree, the BMI 270 is the best option.

[@LehtusBphree2flyFPV]

I'm disappointed with speedybee I ordered 3 of they're latest stacks out of 3 one worked the others are connected to transmitter but won't work when you arm the drone. The first one that worked was fine and then without any crashes the ESC stopped working. But cheap get cheap crap

[@rgglenn150]

my friend bought 2 stacks of the v3. 1st one has desyncs.. 2nd one has motor twiching. Didn't event fly properly. Just hovers and drops off the sky. I guess esc quality is bad

[@LehtusBphree2flyFPV]

@@rgglenn150 their new batches are on point now. Seems to be when a company rushed a new product out that send all the bad ones out then see the complaints then fixes the problems for the 2nd batch. Speedybee f stack are getting better and better at this price point. Now other companies are following this trend. Goku is making cheaper stacks now but no Bluetooth built in.
