If your spot any missing FC, or you are the manufacturer who want to have your product listed here, feel free to let me know.

What’s a Whoop FC?

Whoop flight controller has a 25.5×25.5mm mounting pattern.

whoop flight controller fc 25.5mm mounting pattern

They all have ESC, FC, OSD integrated in the same board which is also known as AIO FC.

Some of these boards even have integrated radio receiver as well as VTX, which is ideal for those who want to save an extra couple of grams.

They are intended to be rotated 45 degrees when mounting in the frame.

What’s a Toothpick FC?

Toothpick is a type of ultralight FPV drone, they have skinny arms that look like toothpicks hence the name.

Whoop style FC has been around for years, and they were “borrowed” in Toothpick builds for their compactness. But manufacturers have been refining and tailored a specific type of FC just for the toothpick builds.

Toothpick style FC has the exact same mounting pattern (25.5×25.5mm) as whoop FC, but they are typically slightly wider to accommodate for the extra solder pads. Motor connectors are generally avoided due to theirs higher resistance, though it’s not an issue for the lower performance whoops.

toothpick flight controller fc 25.5mm mounting pattern

They also have more powerful ESC, with certain AIO board supporting 6S up to 55A.

The USB connectors are usually oriented horizontally, instead of pointing downward which is commonly done in tiny whoops.

Mounting Pattern

The real mounting pattern should be 1 inch (25.4mm).

But due to the lack of standard, you may see 25.5mm, 26.0mm or even 26.5mm from different manufacturers. The difference is small and so it shouldn’t cause problems when mounting in frames as far as I know, but it’s a good idea to stick with 25.5mm to avoid surprises.

Choosing the right FC for your build

Some of these whoop-style FC are designed for very specific purposes. Ask yourself these questions will help you filter the options down to a handful which makes it easier to decide.

  • Is it designed for whoops or toothpick frames? Some FC are designed specifically for toothpicks and tricky to fit in whoop frames
  • What LiPo voltage does it support?
  • ESC current rating
  • Motor connections – direct solder or “plug and play”
  • Integrated receiver and VTX
  • Extra UART for things like DJI Air Unit / Vista, GPS etc.

Here I will talk about some of the most interesting and iconic flight controllers.

Happymodel X12 AIO 5in1 ELRS FC V2.0

Happymodel X12 Aio 5in1 Elrs Fc

They didn’t sell this FC separately unless you get the Mobula6 or Mobula7. Now you can get this FC separate to upgrade your existing whoop or as replacement.

Happymodel DiamondF4 AIO with OpenVTX (ELRS / Frsky)

Creator: Gd Jpeg V1.0 (using Ijg Jpeg V62), Quality = 80

This FC is in the new model MoBeetle6. This is exciting for those who want to build a tiny whoop with ExpresLRS built-in. Problem with SPI receiver is, in order to update ExpressLRS you have to update Betaflight. The upside is it doesn’t take up an UART and it’s more compact.

Crazybee F4 Pro V3

Product Page: http://bit.ly/crazybee-f4-v3

Crazybee F4 Pro used to be an affordable board, but the latest V3 board requests a premium but does have its reasons. This is the latest and greatest for the micro brushless quadcopters offering an integrated RX for both DSMX and Frsky, a clean layout in a relatively light product.

It offers 2S-4S battery compatibility as well as standard whoop mounting, allowing for a wide range of uses in a variety of different sized and style micro quadcopters. If you are able to stretch the budget to this FC, this would be a very good choice.

Here is a detail overview of this FC, and all the changes since V1.

BetaFPV F4 AIO 2-4S V3 (12A / 20A)

Product Page

Although this board has 26x26mm mounting so it could be put on a 65mm frame, it seems that this board is designed exclusively for 75mm, 85mm and 95mm style whoop frames. The higher voltage support up to 4S LiPo would be better suited with lower KV motors and larger propellers, so you would be able to get all of the performance out of this board.

Be aware this board does not come with integrated RX, therefore you would need to connect your own. When it comes to brushless whoops, the added weight of an external RX doesn’t have such a negative effect as their brushed counterpart. Brushless motors provide more propulsion, so having to add an RX won’t be much of an issue – especially with the extra room that a 75mm tiny whoop frame would provide.

BetaFPV F405 2-4S AIO Toothpick FC

Product Page: http://bit.ly/33r3fXm

The GEPRC FC looks like a contender for the Crazybee F4 Pro V3 as it also accepts 2-4S. All of its features are similar except it doesn’t offer any integrated RX support, which shouldn’t be too much of an issue on something that can carry the added weight.

This downside is offset by its cheaper price coming in at £33.46 compared to the Crazybee’s premium price of £40. Both boards appear to be a very good choice, so it’s up to you to decide if you want an integrated FC or not.

iFlight Beast F7 H7 AIO

Product Page

The iFlight Beast AIO flight controller has two versions, the F7 and H7, they have similar specs with a few differences. The H7 is a faster processor and hence more future proof. But as for now there is little to none advantage of using the faster H7 MCU. Also, the H7 has more powerful MOSFET and higher current rating at 55A. Therefore the H7 is $20 more expensive than the F7. Both FC is powerful enough to be used on 5″ freestyle FPV drones.

One you could add to the list here is the BetaFPV F4 AIO ELRS 1S 5A V2 FC. Thid is similar to the Happymodel CrossF4 in features and shape (a cross). It is light, has serial as opposed to SPI ELRS thus decoupling ELRS code from Betaflight, comes with and without motor connectors. Doesn’t have a buzzer, but does have 8MB logger memory.

It’s a very well specified board for a whoop. However, I have had reliability issues (three out of four have failed). Not clear why. Maybe I’ve been unlucky, maybe not. I added some comments on this to your review of the V1 board (which doesn’t have serial ELRS) – see https://oscarliang.com/betafpv-elrs-f4-1s-5a-aio-fc/.

Kevin 23rd March 2023 - 4:30 am

I know you & your audience is primarily flashing betaflight but I was hoping to build a micro for Inav with a few parts as possible (it’s a micro!) Was hoping you’d cite FC’s available targets as well. Specifically I was looking for an AIO that I could load INAV to that had both a Baro & a ELRS. A pretty tall order, I know- but that’s how I ended up at this page.

João Henrique 31st July 2022 - 8:22 pm

Hi, Oscar! You make a very good job for the community, thanks!
My question is: I have an old Bugs B3 pro, without main board, laying around. 1800kv motors and 12amps escs are perfectly working. Can I use an AIO like Jhencu GHF411AIO, in it? Specs says it have a 40Amps esc, theoretically can handle with the 1800kv motors. Am I wrong? Thanks in advance!

Oscar 31st July 2022 - 11:05 pm

If it had 12A ESC before and it worked fine, then 40A ESC would be more than sufficient, in that case, yes, it should work.

gozeel 9th January 2022 - 2:10 pm

Hi oscar, nice to meet you. I have a Board Whoop lite brushed 1s. can elrs be installed?
and how?
Thank you in advance

Oscar 10th January 2022 - 12:26 pm

If there’s a spare UART available, then yes.

Juanma Granja 2nd January 2022 - 1:24 pm

Wonderful article.
I think there is a typo at item “14.-BetaFPV F405 2-6S AIO Toothpick FC”
Title points to 405, while you are describing “F722”.

Ive been working on a 40mm prop, 65mm wheelbase whoop and thought i had it all sorted then i picked up that the EACHINE board isnt 25.5 x 25.5mm..
its 28.5 x 28.5mm… which means my model needs to be redone, and it probably can only be achieved using inverted ducts. i do want to point out that the board is 28.5 x 28.5mm, which is really important as it means that the UZ frame isnt compatible with many others also.

_n345 3rd November 2021 - 2:49 pm

although i see blackbox in specs, it would be nice to have blackbox in the table.

What’s the difference in iflight’s H7 beast version 1 versus version 2. Is it just that with version to the use of jesc firmware is stable? Is version 1 flyable with the stock firmware?

CL Racing F7 Whoop AIO V3
Do you see a solution to fix a external Buzzer on that FC? How about with a UART?

X3 16th June 2021 - 12:42 pm

Thanks Oscar for what you do on this site !

Also, just to let you know tat BetaFPV released a 1S 12A Toothpick AIO :betafpv.com/products/f4-1s-12a-flight-controller

Oscar 17th June 2021 - 2:39 pm

Thank you, FC added to the list now.

Mike 12th June 2021 - 12:10 am

FYI . The Diamond F4 weights 2.94 g

Nikotttin 5th June 2021 - 11:20 pm

Just to tell people that I was one the unlucky bastards out there. Both of my 1S FCs burned in flight and after 5-10 flights. My JHEMCU
25a had an issue and never got recognized by my pc. Finally I’ve had soooo many crazybee F3 having the 5v regulator Breaking that I’m ashamed to say it…
I actually have an old box with old dead FC’s.
Lastly very happy to report that the JEHMCU play f4 1-2S is still working 1 year after buying it. Best one but also likely pure luck ?

Nikotttin 5th June 2021 - 11:21 pm

Gosh I meant to say the betafpv 1S… Apologies!

John Th. 1st September 2021 - 2:02 pm

I have to agree, on the BetaFpv AIO i received with the Tiny Trainer kit, 2 fc’s died on me. On the inital piece that came w the kit, there was an power issue. GetFPV sent yet another, all was good until i connected to BLheli32, changed direction of one motor, then 3 escs blew.

3rd FC to be delivered this week, im not hopeful. So i ordered a JHEMCU GJF11 Pro, which i have on another quad, in addition. I plan to not install the BetaFPV board or maybe keep it for a later build. Too much of a bitter taste left!

JuHu 5th June 2021 - 1:16 am

Don’t forget NBD Hummingbird f4 pro. It’s pretty unique.

Oscar 5th June 2021 - 12:02 pm

How did I miss that one? :D thank you!

Cerum 3rd June 2021 - 4:51 pm

There is also one from Darwin now. pyrodrone.com/collections/whoop-style-aio-flight-controllers/products/darwinfpv-15a-1-3s-f411-ultralight-whoop-aio

Oscar 3rd June 2021 - 7:07 pm

Thanks will add to the list.

Marc Frank 3rd June 2021 - 4:30 pm

i would avoid the hglrc zeus boards
i’ve had two in a row with cold solder joints

OJW 7th June 2021 - 12:55 pm

Agree – 2 fails for me. I was able return one that rebooted continuously. The other had a gyro fail after a few flights. Won’t buy any more of these.

SunnyRFF 29th November 2019 - 12:29 pm

So I’m not big into the OSD thing, and my DockKing has a basic one built in. So if I am not worried about updating that or other features, can I still configure F3 on and older version of BF, like 3.5 or even 4.0? Basically it’s just my goofing off around the house whoops, that I let friends and family fly, so as long as I don’t update the firmware, can I still go in and tweak things?

SunnyRFF 29th November 2019 - 12:21 pm

Why not? Just because you thought they’d lose popularity? No doubt brushless Micros and toothpicks are fun to fly and all the rage, but what about intermediate skilled fpilots, or kids/seniors or anyone that doesn’t feel the need to go balls out when they fly. Maybe they are happy flying indoors, or they live somewhere with crappy weather or they’re disabled and it’s hard for them to go outside. Think man, think.

Tom 1st October 2019 - 9:23 am

Could you please recommend me a brushless FC with i2c or with barometric sensor? Or should I use some bigger FC? I would like to build 1-2S brushless FPV tiny whoop with altitude hold (since it is for children with no experience, but we need to fly them outdoors) I have several Emax tiny hawks, but without the altitude hold its too compicated for them to use it. Since I am unable to find rxtx barometric sensor to add to tinyhawk, I would like to build something in betafpv 75.

Kosdon3200 24th September 2019 - 5:23 am

Love your site! I think you misspoke here and intended to say this about brushless:

“Brushed motors provide more propulsion, so having to add an RX won’t be much of an issue – especially with the extra room that a 75mm tiny whoop frame would provide.”

Keep up the great work!

Merrill 11th August 2019 - 5:52 pm

The Ailenwhoop Zero and Beecore Lite boards can be tuned, just not using Betaflight. They run a firmware called Silverware, which was originally made to allow toy quads, such as the E011, to fly acro. There are a few tutorials online. These boards are flashed the same way. I am not sure about the stock settings on those boards, but you may be able to tune the PIDs using stick gestures, as seen here – sirdomsen.diskstation.me/dokuwiki/doku.php?id=pidgesture.

I wrote an Eachine E011 firmware upgrade tutorial – instructables.com/id/Eachine-E011-Mods-Cheap-Tiny-Whoop/. This is my first acro quad, and I think it would make a great first whoop, especially for $20.

Gianpa 11th August 2019 - 2:59 pm

You killed it as always! You are the best!

MrCookie 24th January 2018 - 4:59 am

If you check alienwhoops v2 page, it weighs 3.5g

justAprop 29th August 2017 - 3:34 pm

Why still invest in a tiny whoop when there are so much good micro brushless quads? My King Kong GT90 performance better in every single way and it costs 2/3 of the price of a thiny whoop. Sry dude, but the end of the tiny whoop era is near….. ;-)

XeroPhane 29th August 2017 - 9:55 pm

How easy is it to fit a frsky reciever to your King Kong GT90?

Dave 7th September 2017 - 10:25 pm

Whoops fly really smooth indoors, whipping around the house, between chair legs, etc. They’re really quiet, nearly indestructible, don’t hurt when they hit someone, and they’re TINY. Brushless micro quads are fine, but more power and more speed isn’t always better. Whoops are a lot of fun. Sry dude, but the end of the tiny whoop era is nowhere in sight.

Michael Morgan 6th January 2019 - 7:37 pm

Sry Dude, tiny whoops thrive 1.5 years later. 255g mean anything? One local “hot shot’ “star” “ace” lost an eye flying into his own face. Sry I laughed. Thanks to “dudes” like this, the FCC is getting prepared to shut it down. We need better than clown farts to defend the hoppy. Idiots ruin so much.

Asterios Anagnostou 15th March 2017 - 4:42 pm

Hey everyone! A quick question. I’ve modified the heck out of my inductrix and the latest mod, to get more flight time, was trimming my props to two blades. It increased flight time by 1 minute, which was great, but now it oscillates like a paint mixer. Will one of these fc’s help me fix this issue? Someone mentioned on YouTube that it’s the p factor causing the oscillation, especially since I have 17k motors, and that you can tune the board to compensate. Which boards are the most user friendly for tuning and do you think this will work? Thanks in advance!

GomenKitfo 6th February 2017 - 4:43 pm

The Acro-woop is bad ass. I didn’t notice the weight difference. I did notice the board looks complicated as hell when compared to the BeeBrain. The receiver is also a add on board. The thing seems to suck an incredible amount of juice. I’m not sure the telemetry info is worth it to me. I have definitely experienced decreased flight time. So far the bee brain has been the best option for me

chris peters 13th May 2017 - 10:16 pm

Hey do you know how much you lost? I switched to the acrowhoop and dropped like 2 min.

Rich 16th January 2017 - 5:11 am

Theres also the boldclash queen spr f3 brushed flight control with built in frsky for only under $20.

NW 1st January 2017 - 9:35 pm

Thinking of using the Beecore, but what’s the best way to monitor the cell voltage?

Brandon 18th December 2016 - 5:16 pm

I got the beecore and built my tiny whoop. And I loved it it was great I loved flying around I had about 10 flights on it. Then all of a sudden anytime I plugged in the battery the motors just kept spinning up it didn’t matter if the transmitter was turned on or off armed or unarmed any kind of power going to it and the motors would just spend up. I can’t seem to get it to stop which means currently it’s not flyable. What can I try to get this thing back on the air? I’ve already gone back through the rebinding process and even reset the board but nothing seems to work. Am I doing something wrong or do I have a bad board?

Jason 12th January 2017 - 6:35 am

Blown FETS. Bad board now.

ido 16th December 2016 - 8:44 am

Great overview, I am looking into getting another FC for my tiny whoop.

I am seeing that all FC’s wont work with a EU version of Taranis, what options does someone with an EU Taranis have, without stating the obvious (flashing my Taranis with non EU firmware).

koss 10th December 2016 - 8:19 pm

Technically that’s not all the options — There’s the Makerfire – amazon.com/exec/obidos/ASIN/B01M72IXMU and This one supposedly fits and is very cheap gearbest.com/multi-rotor-parts/pp_590130.html?wid=21 maybe others?

Bob Corder 4th December 2016 - 12:19 am

How can I connect a Bee Core DSM FC to Beta Flight and get it to bind to my Skektrum DX6i TX?

François 4th July 2017 - 1:46 pm

Did you manage to add a spektrum DSMX satellite ?

ScottAllyn 21st November 2016 - 2:45 am

The BeeBrain works great in an E010 frame, with full access to the USB port with just a tiny bit of trimming. Simply trim the battery tray front stop so that a battery can slide in from either direction, then install the BeeBrain rotated 180 degrees so that the front of the frame is now the back. The USB port may still contact one of the top braces on the battery tray, but that won’t prevent a USB connector from going in… and a few swipes with a needle file will fix even that:



Oscar 22nd November 2016 - 2:02 pm

that’s good to know!
