No time building a DIY tiny whoop? You can just buy one off the shelf. Here is a roundup of some of the best Tiny Whoops on the market.
Tiny Whoop FC are divided into brushed and brushless depends on the type of motors they are running. Here is an in-depth discussion on the differences in brushless and brushed tiny whoops.
Here is the comparison table of all the brushed whoop FC, click FC name to see detail.

We didn’t include many flight controllers with F3 MCU because that’s no longer supported by the latest Betaflight firmware. However we’ve given Honorable mentions to the iconic few.
The stand-out brushed whoop flight controller for me would be the Beebrain Lite purely because it allows for smart audio and have Betaflight OSD. Unfortunately, it appears that you can only buy this FC as a package hence the steep price.
As an alternative, I really like the BetaFPV F4, but only if you’re using Frsky or DSMX receiver. That’s because it comes with integrated receiver that either support Frsky and DSMX. You could solder up an external RX to it, but that only adds weight and complication on something where every gram counts.
For those flying Flysky and want an integrated RX, BetaFPV offers an F3 board but it is becoming outdated, hence why we didn’t include it on the list. Beecore V2 is another good option but again it uses the “old” F3 processor. It is however one of the cheapest whoop FC’s and does have support for all integrated receivers, as well as BFOSD.
Some trends with the newer FC’s are emerging.
F4 is becoming the standard due to the bloated Betaflight codes and features. Nearly all FC’s now have integration of Betaflight OSD, as well as SmartAudio so you can change VTX settings in the OSD with your sticks. Turtle mode is still limited, (only the Nanowhoop FC and the Eachine Turtlebee F3 support it) so we can’t expect this to be widely adapted just yet.
I think integrated RX’s that support all the main transmitter types are quite essential, because I feel as if external RX’s complicate builds on such a small level and add weight. But for some it may not be as big of a deal and allows you to use whatever RX you feel like, so it is really based on what you want to do with your whoop.
For me, the ideal FC should have at least one UART for SmartAudio, integrated RX, supports Turtle Mode and BF OSD, an F4 processor and high rated MOSFET’s for durability. We have not reached this standard yet but hopefully one of the manufacturers will try and achieve something similar to this.
It is also worth noting that higher rated MOSFET’s normally are not only more reliable, but also have lower internal resistance, which allows for a more responsive and powerful feel from the motors. This, in theory, allows for a greater flying experience, hence why this was used for a point of comparison on the table as it can be quite a big deal in the brushed FC’s.

The Beebrain Lite is feature packed as explained in my review. This FC has a good reputation, so buying one of these wouldn’t be something you regret if you have the budget for it. One disappointment with this board though is that it only come with Frsky integrated receiver, therefore making it less accessible to everyone that doesn’t fly Frsky.
This FC appears to only be available in a bundle with a VTX and FPV camera, which might put off those that already have an FPV setup and are just looking for the flight controller.

The Beebrain V2 is an older brother of the Lite, and is in need of an update as it still uses an F3 processor. However, it does also support SmartAudio and Betaflight OSD so if you don’t mind slightly older hardware this might still be a good choice as we reviewed it here. This FC supports Frsky and DSMX so it is more accessible than the Beebrain Lite .

The Alienwhoop offers good flight characteristics and has built a reputation for being the “KISS of the whoop FC’s”. This FC is set up right out the box to fly how ‘NotFastEnuf’ and ‘MontiFPV’ (pilots) intended, with “powerful MOSFET’s” to aid in your flying ability.
However, this FC has no USB for you to connect to the computer, so fine tuning is not possible. It also requires an external RX so will add to the weight of your Tinywhoop. It is only 2.6 grams however, so it is one of the lighter FCs on the list. It also does not have OSD, which is a bummer for me personally.
Eachine Turtlebee F3
Product Page: http://bit.ly/31ojAdy
This FC offers a variety of integrated RX’s and is on the cheaper side of the whoop FC, making it a good buy for people with a tight budget.
Its biggest strength is the fact that it’s one of the few FC’s on the list to have turtle mode (alongside the Nanowhoop). Turtle mode allows you to flip the quad back over in a crash, instead of having to get up and get it every time you crash somewhere around the house or in a race.
If this FC offered higher rated MOSFET and smart audio (as well as an F4 processor), it would have easily been one of the best whoop flight controllers on the list.
Beecore Upgrade V2.0
Product Page: http://bit.ly/2KkqP0f
The Beecore is for people that aren’t fussed about having the latest and greatest flight controllers. It’s very cheap, offers support for most transmitters, has an OSD and is pretty light-weight. It may have an F3 processor and lack some other useful features, but for the price you cannot really complain.
BetaFPV F4 Brushed FC
Product Page: https://amzn.to/2YQnEFD
BetaFPV has made a name for itself in the Tinywhoop industry for having some of the most cutting edge micro quad components and BNF kits. They offer good products for a good price, and always try to stay on top with constant new releases of their products.
However, they appear to be slacking with their brushed FCs as they only offer support to Frsky and DSMX with this particular FC, making it less accessible to other users such as Flysky.
One strength of the BetaFPV F4 is that it claims to be using 30A MOSFET’s. If that wasn’t a typo, it’s a massive overkill considering brushed motors used in Tiny Whoop typically only draws 2-3A. Higher rated MOSFET is more robust, and allows for better control of the throttle with a more responsive feel.
I would really love to see BetaFPV to have this board support more receiver options, as well as adding Turtle mode to the list of features to justify for the slightly more premium price that they are asking.

The Alienwhoop is regarded by the tiny whoop community to be one of the best flying flight controllers, hence its big premium.
The Alienwhoop v2.1 offers an overclocked F4 processor and what they described as “overkill MOSFETS” to try and be the best flying FC for brushed whoops that money can buy. However we couldn’t find out what the MOSFETS are rated to, I can only assume it’s something similar to what the BetaFPV F4 did there?
However, just like the Alienwhoop Zer0, it doesn’t offer any integrated RX support, so you will have to solder up your own, and decide if the added weight of an external RX is worth the supposed “incredible flight characteristics”.

The Beecore Lite is an extremely basic tiny whoop flight controller, only offering an integrated RX that only supports ‘Bayang radio protocol’ which is used in a lot of toy RC remotes. If you own a Jumper radio or multi-protocol module, you can actually control it with it.
It has no USB so you change any of the settings. But if you have a transmitter that is able to connect, it would make an extremely cheap and easy build at only £13 for the FC.
Eachine Beecore VTX
Product Page: http://bit.ly/2MJWLwP
Yes, it has VTX in the name, but it’s actually a whoop FC.
This FC tried to do something different and I commend its attempts. Instead of having an integrated receiver like a lot of other whoop FC’s do, the Eachine Beecore VTX has an integrated video transmitter which supports SmartAudio.
This would give you a lower profile whoop as you would only need a tiny camera and you could lie your external RX flat on top of the FC, making for a very low-profile stack.
However, most of the cameras for Tiny Whoop usually come in the form of “AIO” (all in one), where there is VTX attached to the back of the camera. Therefore, your camera options are limited to nano FPV cameras, such as the Runcam Racer Nano.
Here is the comparison of all the brushless tiny whoop FC:
Brushless whoops have more or less the same features as brushed whoop. One extra thing we need to look out for though is the voltage support, since brushless motors can be powered by much higher voltage than just 1S LiPo.
All of the popular Brushless whoop flight controller nowadays have the same MCU’s and gyro combo, i.e. F4/MPU6000, supports DShot600 ESC protocol and all have the option to use Betaflight OSD. The reasoning for this is because the Brushless micro scene is fairly new (much newer than the brushed micros), so they are all using the most recent hardware to base their FC’s on, which happens to be the same processors.
The standout FC in this category is the Crazybee F4 Pro V3. You are paying a premium for this FC, not only it’s one of the latest, but it has the most features and support up to 4S. It is relatively light (4.3g) and offers support for integrated Frsky and DSMX RXs. Not only it’s a great Tiny Whoop FC, it’s also great for a toothpick style micro quad.
As for people flying 1S and 2S on a typical 65mm tiny whoop frame, the BetaFPV boards seem like the standard choice. The Beecore is slightly cheaper and is essentially the same board, but offers no integrated radio receiver options (Betapfv offers a Frsky option).
BetaFPV F4 AIO 12A
Product Page: https://amzn.to/2Mazx3q
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 style frames and up. 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. 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.
I believe this FC would be best suited for a toothpick style frame to get the most performance out of it.
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.
GEPRC GEP12A-F4 V1.1
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.
BetaFPV F4 1S
Product Page: https://amzn.to/2Kty9XE
This FC is a standard choice when making a 65mm Tiny Whoop. Its relatively cheap, comes with all the features that you would expect from something at this price range and has a Frsky integrated RX. I would have liked to see more integration for other RX’s for something that is at this price range and is so widely used to improve its accessibility to people that don’t use Frsky transmitters.
BetaFPV F4 2S
Product Page: https://amzn.to/2YVrTji
This FC is essentially the same board as the previous “BetaFPV F4 1S”, but allows for the use of 2S batteries as well as 1S, and offers Futaba as the addition RX option. Its slightly heavier but its beefier hardware gives you the freedom of choosing either 1 or 2S power, and is more reliable even running on 1S, allowing for more powerful builds if you feel the need to.
Beecore BL F3
Product Page: http://bit.ly/2KHz6dt
The Beecore is the cheapest flight controller for brushless tiny whoop on the list. The low price may be down to using older generation hardware and not including any integrated RX support. It does however have Betaflight OSD and the ability for SmartAudio, so if you aren’t worried about what type of processor it uses, and want to build a brushless 1S micro on a budget, this is the board for you.
