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.

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.

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.

This FC is a standard FC for a 1S 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 as well as a 25mW VTX. It’s a very convenient and low profile FC to use if you care about weight and space.

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.

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.

GEPRC GEP12A-F4 V1.1

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

Whoop and Toothpick Flight Controllers Round Up
Whoop and Toothpick Flight Controllers Round Up

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.
